TL;DR

A strong Performance Test Engineer resume combines workload design, scripting, systems analysis, observability, and business decisions. Use a simple reverse-chronological layout, lead with relevant evidence, quantify only measured outcomes, and tailor terminology to each posting without copying unsupported keywords.

Key Takeaways

  • Lead with performance engineering outcomes and system depth, not a dense inventory of testing tools.
  • Write experience bullets as scope plus action plus technical mechanism plus measured result or decision.
  • Use exact job-description terminology only where your experience genuinely supports it.
  • Show workload modeling, script quality, observability, bottleneck analysis, and stakeholder communication as one workflow.
  • Replace every illustrative metric in a template with a measured, explainable figure or an honest qualitative result.
  • Give early-career projects production-like controls, including authorized targets, functional checks, telemetry, and limitations.
  • Tailor the summary, skills order, and strongest bullets for each role while preserving a simple ATS-readable structure.

A strong Performance Test Engineer resume example proves that you can design valid workloads, generate correct traffic, diagnose system constraints, and turn evidence into release or capacity decisions. It should not read like a list of JMeter listeners, cloud services, and monitoring dashboards. Hiring teams need to see what you tested, how you tested it, what you learned, and what changed because of your work.

This guide includes a complete fictional resume, bullet formulas, early-career and senior variations, an ATS tailoring method, and a runnable k6 portfolio sample. Every number in the fictional example is illustrative. Replace it with a metric you personally measured and can explain, or use a precise qualitative result.

The target is an honest interview-generating document. A keyword can help matching, but unsupported claims usually fail technical drill-down.

TL;DR

Resume area Include Avoid
Headline Target role and strongest specialty Looking for opportunities
Summary Experience, systems, core tools, outcomes Generic passion statements
Skills Grouped role-relevant technologies Every tool ever opened
Experience Scope, action, mechanism, evidence, decision Task-only job descriptions
Projects Objective, workload, environment, results, limits Public-site load tests without permission
Metrics Measured figures with explainable baselines Invented percentages and vanity counts
Format Simple headings, readable text, consistent dates Columns, graphics, and critical text in icons

The fastest improvement is to rewrite the top six bullets so each demonstrates a performance engineering decision rather than a responsibility.

1. Performance Test Engineer resume example strategy for 2026

Performance roles increasingly overlap with software engineering, site reliability, platform engineering, cloud, data, and DevOps. A resume should therefore communicate both load-testing craft and system reasoning. The exact balance depends on the posting. A JMeter-heavy enterprise role may value Java, protocol support, distributed execution, and detailed reporting. A cloud-native team may emphasize k6 or Gatling, code review, CI, containers, metrics, traces, and infrastructure behavior.

Start with a target-role scorecard. Extract required outcomes, protocols, languages, tools, platforms, observability systems, databases, and collaboration expectations. Mark each as direct evidence, adjacent evidence, learning project, or unsupported. Your strongest direct evidence belongs in the top third of the resume. Adjacent skills can appear when clearly framed. Unsupported keywords should not be added merely for ATS matching.

Choose one professional identity. Performance Test Engineer | API and Cloud Workloads | k6, JMeter, Grafana is clearer than QA | SDET | DevOps | Scrum Master | AI Expert. A broad career can still be represented through selected evidence, but the reader should understand the role you want within seconds.

Read the posting for seniority signals. Execute scripts favors hands-on tool evidence. Define strategy, influence architecture, capacity planning, or mentor requires ownership and cross-team decisions. Use the performance engineering career roadmap to identify missing capabilities, then represent only completed work on the resume.

2. Show what a hiring manager is actually evaluating

A hiring manager looks for a chain of competence. Can you translate business behavior into a workload? Can you implement reliable scripts with dynamic state and data? Can you prove the generator and environment were valid? Can you read client and server signals? Can you distinguish observation from bottleneck hypothesis? Can you communicate a decision and work with developers to verify improvement?

Your resume should reveal that chain across multiple bullets. One bullet may explain workload modeling from approved traffic data. Another can show reusable script engineering and functional checks. A third can show correlation of latency with database pool wait or queue backlog. A fourth can show a controlled rerun after a code or configuration change. A fifth can show CI feedback and governance.

Depth also appears through nouns and boundaries. Reduced response time is vague. Compared checkout p95 and completed order throughput across identical steady intervals, then correlated increased database connection wait with the regression is credible even before a result is stated. Add the actual measured outcome only if you own and understand it.

Hiring teams also assess safety. Performance tests can disrupt systems, consume cloud budget, trigger third parties, and create data. Mention authorization, abort controls, environment coordination, generator monitoring, or test-data lifecycle when relevant. These details differentiate engineering work from simply increasing thread counts.

Finally, they assess communication. Include examples of release recommendations, capacity findings, architecture reviews, defect reports, or dashboards that supported an owned decision. Avoid claiming sole credit for a multi-team production improvement.

3. Choose an ATS-readable resume structure

Use a reverse-chronological structure for most candidates: header, target headline, summary, skills, experience, projects when useful, education, and relevant certifications. One page can work for an early-career candidate. Two pages are reasonable when an experienced engineer has relevant depth. Do not compress ten years into unreadable text to satisfy a rigid one-page myth.

Use standard section headings such as Summary, Technical Skills, Professional Experience, Projects, Education, and Certifications. Keep contact information as real text. Avoid placing critical content only in headers, footers, icons, images, or decorative charts. A simple single-column layout is safest for parsing and human scanning.

Dates should be consistent, for example Jan 2023 to Present. Locations and work modes are optional unless useful. Use conventional job titles, and add a clarifying parenthetical only when an internal title would confuse an external reader. Never silently promote yourself from Tester to Lead.

Order sections by evidence strength. An experienced engineer normally puts professional experience before education. A career changer with a strong recent performance project can place Selected Performance Engineering Projects after the summary and skills, then show prior transferable experience. A new graduate can lead with skills and projects if employment is limited.

Export to PDF only after checking text selection and extraction, unless the employer asks for another format. Keep a clean source document and a plain-text version. Name the file professionally, such as FirstName-LastName-Performance-Test-Engineer-Resume.pdf.

4. Write a specific headline and evidence-based summary

The headline should match the target role and one or two differentiators. Examples include Performance Test Engineer | API, Database, and Cloud Workloads, Senior Performance Engineer | Capacity, Observability, and CI, or QA Engineer Transitioning to Performance Testing | JMeter and SQL. Do not use a senior title unless your actual scope supports it.

A summary needs four ingredients: level or relevant experience, system or domain scope, strongest methods and tools, and the outcome you enable. Keep it to three or four lines. Avoid first-person pronouns if the rest of the resume uses fragments, and avoid traits that have no evidence.

Weak summary: Hardworking performance tester with knowledge of many tools and excellent communication skills seeking a challenging position. It consumes space without differentiating the candidate.

Stronger summary: Performance Test Engineer with 6 years in API and transaction platforms, designing k6 and JMeter workloads from production traffic models and correlating results with application, database, and Kubernetes telemetry. Experienced in capacity baselines, CI regression checks, and controlled bottleneck experiments that support release decisions.

Every phrase creates an interview obligation. If you say production traffic models, explain the source, cleaning, time window, and assumptions. If you say Kubernetes telemetry, explain the metrics and a real finding. If you say capacity, explain criteria and configuration. Remove any phrase you cannot defend under three follow-up questions.

Tailor the summary last, after selecting experience bullets for the role. That ensures it summarizes evidence actually present in the document.

5. Build a focused technical skills section

Group skills so both a parser and engineer can understand them. Useful categories include Performance, Languages, Protocols and APIs, Observability, Data, Cloud and Platforms, and Delivery. The categories should reflect the role, not a universal template.

Example:

  • Performance: k6, Apache JMeter, workload modeling, correlation, parameterization, thresholds, distributed execution.
  • Languages: JavaScript, Java, Python, SQL, Bash.
  • Protocols and APIs: HTTP, REST, WebSocket, gRPC where genuinely used.
  • Observability: Prometheus, Grafana, OpenTelemetry, application logs, distributed tracing.
  • Data: PostgreSQL, Oracle Database, query plans, connection pools, Redis.
  • Platforms: Linux, Docker, Kubernetes, one relevant cloud.
  • Delivery: Git, GitHub Actions or Jenkins, code review, test-result retention.

Do not rate yourself with stars, progress bars, or percentages. Java 80% has no stable meaning. If proficiency matters, demonstrate it in experience or projects. Separate hands-on experience from exposure through placement and wording rather than an elaborate legend.

Keep tools current but do not delete valuable foundations. HTTP, SQL, Linux, workload modeling, and measurement transfer across tool changes. Place exact posting terms when accurate, such as Apache JMeter rather than only JMeter, but avoid repeating the same keyword in every section.

Remove office software, generic Agile vocabulary, and basic tools when they crowd out relevant depth. A senior resume should not devote equal weight to defect tracking and workload architecture.

6. Convert responsibilities into high-signal experience bullets

Use this formula as a prompt, not a rigid sentence: scope and risk + your action + technical mechanism + measured result or enabled decision. Begin with a strong accurate verb such as designed, implemented, modeled, correlated, isolated, validated, integrated, optimized, led, or mentored.

Responsibility-only bullet: Responsible for executing performance tests using JMeter and preparing reports.

Stronger bullet: Modeled checkout and refund demand from approved peak-hour analytics, implemented JMeter API scenarios with per-user data and correlation, and delivered a release report covering latency distributions, completed throughput, errors, and database saturation.

Outcome bullet with an illustrative metric: Isolated connection-pool wait as the immediate limiter during a controlled step test; partnered with service and database owners on a configuration change and verified a 24% increase in completed throughput at the same error criterion. Use 24 percent only if that is your actual measured result with a comparable baseline. Otherwise write verified higher completed throughput at the agreed error criterion and explain the evidence in an interview.

Vary the story across bullets. Include workload modeling, script engineering, environment and data, observability, investigation, improvement verification, CI, and collaboration. Repeating executed load tests with different project names does not demonstrate growth.

Keep the most relevant and impressive bullets first under each role. Older positions can have fewer bullets. If confidential details matter, describe scale qualitatively, such as high-volume transaction service, and retain the engineering mechanism. Never substitute invented precision for protected information.

CERTIFICATIONS
Include only current, relevant certifications you actually hold.

Why this example works: the summary establishes scope, the skills are grouped, and the bullets move from model to script to diagnosis to decision. It includes tool keywords without making them the story. It also states an illustrative measured comparison with the necessary baseline conditions.

What it still needs before use: real contact details, real employers and dates, exact personal scope, measured figures, relevant technology, and tailoring to a specific posting. Do not copy the fictional metric, adoption count, mentee count, or system domain.

8. Adapt the resume for early-career and career-change candidates

An early-career resume can prove process even without production scale. Build a service locally or in a cloud account you control, ideally with a database and observability. Define an illustrative objective, architecture, workload assumptions, test data, safe limits, monitoring, and limitations. Run a smoke check, baseline, controlled step test, and one hypothesis experiment. Publish sanitized scripts and a short report.

A useful project bullet is: Built a k6 arrival-rate study for a containerized catalog API and PostgreSQL database, validating functional responses and generator delivery while correlating latency with connection-pool and query telemetry. Add an outcome only after performing the work. Created 500 test cases is less valuable than a smaller project that demonstrates experiment validity.

Career changers should translate adjacent evidence. A functional QA Engineer may have API automation, SQL, production investigation, CI, test data, and release communication. A developer may have profiling, benchmarks, concurrency, database optimization, and observability. An operations engineer may have capacity, incidents, dashboards, cloud, and automation. Reframe truthfully around the performance decision, not a title you did not hold.

Keep unrelated history concise but do not erase it if it explains transferable skills and chronology. A customer support role can demonstrate incident evidence and stakeholder communication. A data role can demonstrate distributions and SQL. Use the summary to explain the transition and projects to prove recent hands-on ability.

Avoid public-target load tests. A GitHub repository that shows you generated harmful traffic is negative evidence. State ownership or authorization in the project documentation and include configurable safety limits.

9. Show senior and lead-level scope without vague leadership claims

Senior performance engineers influence architecture and decision systems. Bullets should show how you established strategy, governed criteria, improved shared capabilities, led capacity or resilience work, coached others, and changed design before late testing. Led performance testing activities is too vague. Name the consumers, decision, technical mechanism, adoption, and result.

Examples:

  • Established a risk-tiered performance strategy for eight services, defining per-change component checks, scheduled representative workloads, capacity reviews, artifact retention, and owner-based triage.
  • Facilitated an architecture review of synchronous fan-out and retry behavior, resulting in a bounded-load experiment and an agreed backpressure design before release implementation.
  • Migrated three teams from shared GUI-authored scripts to reviewed code-based workloads through a compatibility period, pilot, documentation, and comparative signal checks.

Use your real scale. Do not copy eight services or three teams. Adoption is meaningful only if you explain who used the capability and how signal was protected during migration.

Senior resumes should also show judgment about when not to run a large test. A component benchmark, query experiment, or production metric review may answer a question faster and more safely. This demonstrates cost awareness, not lack of ambition.

Include mentoring with technical substance. Coached engineers becomes stronger as Reviewed workload models and analysis reports with QA engineers, focusing on open versus closed behavior, generator validation, and observation-to-hypothesis separation.

10. Add a runnable portfolio artifact

A repository should let a reviewer reproduce a safe result. Include prerequisites, target ownership, architecture, seed data, configuration, execution, thresholds labeled as illustrative, telemetry, cleanup, report, and limitations. The script below is a small k6 smoke workload for an authorized local API. It uses one virtual user and a fixed number of iterations to validate wiring before larger work.

import http from 'k6/http';
import { check } from 'k6';

const baseUrl = __ENV.BASE_URL;
if (!baseUrl) {
  throw new Error('set BASE_URL to a service you own or are authorized to test');
}

export const options = {
  scenarios: {
    smoke: {
      executor: 'per-vu-iterations',
      vus: 1,
      iterations: 5,
      maxDuration: '30s'
    }
  },
  thresholds: {
    checks: ['rate==1'],
    http_req_failed: ['rate==0']
  }
};

export default function () {
  const response = http.get(`${baseUrl}/health`, { timeout: '3s' });
  check(response, {
    'health status is 200': (r) => r.status === 200,
    'health body is not empty': (r) => String(r.body || '').length > 0
  });
}
BASE_URL=http://localhost:8080 k6 run smoke.js

Checks in k6 record results, while the checks threshold makes a failed check affect the final process status. This script is not a capacity test and should not be presented as one. Its resume value comes from the larger project around it: documented contract, safe execution, subsequent workload model, system telemetry, controlled findings, and reproducibility.

Link a clean repository from the header or project. Pin or document tool versions, keep secrets out of Git, and provide sample environment variables. Include a result artifact small enough to review and queries or dashboard definitions where possible. The JMeter versus k6 guide can help explain a deliberate portfolio tool choice.

11. Use metrics without inventing evidence

A metric needs a defined baseline, measurement method, boundary, interval, and guardrail. Improved performance by 40 percent is ambiguous. Was it median or p95 latency, completed throughput, compute cost per transaction, test duration, or analysis time? Were errors and workload held comparable? State the measure that informed a decision.

Good resume metrics can include completed throughput at an agreed criterion, operation latency, error rate, queue drain time, resource cost, suite feedback time, investigation time, supported services, adopted teams, execution frequency, or prevented incident class. Not every bullet needs a number. Architecture risk identified before implementation and a clear release recommendation can be valuable qualitative outcomes.

If a number is confidential, use relative or bounded language approved by your employer, or describe scope without scale. If it was never measured, do not estimate after the fact for the resume. Instead of reduced test time 60 percent, write restructured setup and balanced execution to shorten feedback while preserving first-attempt signal, then be prepared to explain available evidence honestly.

Do not confuse generated requests with useful capacity. Executed one million requests says little without operation mix, success, time, environment, and result. Similarly, number of scripts or defects can reward volume rather than value.

Keep a private evidence sheet for each metric: source, calculation, dates, baseline, comparison, your contribution, caveat, and confidentiality status. This sheet makes interview answers consistent and prevents accidental overclaiming.

12. Tailor keywords and bullets for ATS matching

Copy the job description into a working document and highlight exact role title, core capabilities, tools, languages, protocols, platforms, domain, and leadership verbs. Match each item to resume evidence. Use the employer's common term where it is accurate, for example performance testing, load testing, workload modeling, Apache JMeter, k6, SQL, Grafana, or Kubernetes.

Place high-value matching evidence in the headline, summary, skills, and recent experience without repeating unnatural phrases. A parser may recognize keywords, but a hiring manager needs context. Grafana in skills plus a bullet about correlating service and database dashboards is stronger than listing it six times.

Do not hide keywords in white text, paste the whole posting, or add a technology you have only watched in a video. For an adjacent tool, describe the transferable skill and a real learning project. If you used Gatling but the role names k6, keep Gatling experience and mention a completed k6 portfolio rather than rewriting history.

Tailor bullet order. For a database-heavy role, move query plans, SQL, pool analysis, and data distribution upward. For a platform role, emphasize code, CI, containers, observability, and shared libraries. For a consulting role, emphasize discovery, workload agreement, stakeholder reports, and parallel client contexts.

Use a final text extraction check. Search the exported file for target keywords and confirm dates, bullets, and contact details remain in reading order. ATS optimization should improve clarity, not turn the resume into a keyword document.

13. Run a final quality checklist before applying

Check truth first. Can you explain every tool, metric, scale claim, and design decision? Does each job title and date match your records? Are current certifications actually current? Have you removed customer names, secrets, sensitive architecture, and confidential figures that you lack permission to share?

Check relevance next. Does the first half page show the target role, strongest matching skills, and two or three outcomes? Are recent bullets ordered for this posting? Does the document demonstrate workload, script, observation, analysis, and decision? Remove low-value repetition and generic responsibilities.

Check technical precision. Use latency, response time, throughput, concurrency, arrival rate, utilization, and saturation correctly. Say supported a bottleneck hypothesis unless a controlled experiment established stronger evidence. Do not claim exactly-once delivery, zero defects, or production parity casually.

Check writing. Use consistent tense, punctuation, dates, capitalization, and tool names. Present current-role bullets in present tense only for ongoing responsibility, and past tense for completed achievements. Avoid personal pronouns, filler adjectives, and unexplained acronyms. Read aloud once.

Check delivery. Test links, extract text from the PDF, inspect on desktop and mobile, and use a clear filename. Keep an editable master, the tailored version, the posting, and your evidence sheet together. The API Test Engineer resume example can help if the role blends API automation and performance responsibilities.

Finally, compare the resume to likely interview questions. If the document says capacity, workload modeling, k6, database analysis, Kubernetes, or leadership, prepare a project explanation for each. The resume is an agenda you hand to the interviewer.

Interview Questions and Answers

Q: Can you explain the performance improvement on your resume?

Define the baseline workload, build, environment, data, interval, and criterion. Explain the observation, supporting system evidence, controlled change, and comparable rerun. Name your contribution and any remaining limitation. If the number was a team outcome, say so and identify your work precisely.

Q: Why did you choose k6, JMeter, or Gatling?

Connect the choice to protocol support, team language, code review, existing ecosystem, distributed execution, reporting, skills, and migration cost. Acknowledge alternatives. The answer should show that workload validity and analysis would remain necessary with any tool.

Q: How did you derive the workload model listed on your resume?

Describe approved traffic sources, observation window, business-operation mapping, sessions or arrivals, mix, think time, data, peaks, geography, and assumptions. Explain how you validated delivered load and which production differences limited the conclusion.

Q: What was your hardest bottleneck investigation?

Start with the customer or system symptom and run validity. Walk through the timeline of latency, throughput, errors, and saturation, then show how evidence narrowed hypotheses. Finish with the controlled experiment, decision, result, and what you still could not prove.

Q: How do you prevent performance tests from harming an environment?

I secure authorization, schedule with owners, define demand bounds and abort conditions, isolate third parties and data, validate with smoke load, monitor the generator and system, and keep an operator ready. Cleanup and cost controls are part of the plan.

Q: What does your CI performance bullet mean in practice?

Explain which checks run at each cadence, how stable the environment is, how thresholds or baselines are governed, and what artifacts remain. Describe triage ownership and how product, test, environment, and baseline changes are distinguished. A failed gate should not be retried invisibly.

Q: What would you change about your portfolio project?

Choose a real limitation such as unrealistic data, one generator, missing trace context, short duration, or an environment unlike production. Explain how it affects conclusions and the next experiment you would add. This shows judgment better than claiming a perfect project.

Q: How do you work with developers after finding a regression?

Share reproducible workload and evidence, separate observation from hypothesis, and review the request path with owners. Agree on a discriminating change, rerun comparably, and report both improvement and tradeoffs. Avoid handing over a screenshot labeled slow with no model or context.

Common Mistakes

  • Filling the summary with generic traits rather than system and outcome evidence.
  • Listing every performance tool with no project that demonstrates depth.
  • Copying illustrative metrics from a template or estimating numbers after the fact.
  • Describing only execution tasks and omitting workload design, validation, and analysis.
  • Calling correlation proof of a bottleneck without a controlled follow-up.
  • Confusing virtual users, arrivals, concurrency, and throughput in bullets.
  • Using number of requests or scripts as a success metric without business context.
  • Hiding unsupported keywords to manipulate ATS matching.
  • Publishing a portfolio that load tests an unauthorized public target.
  • Exporting a decorative PDF without checking text extraction and reading order.

Conclusion

Interview Questions and Answers

Can you explain a performance improvement claimed on your resume?

I define the baseline workload, build, environment, data, interval, and criteria, then explain the observation and system evidence. I describe the controlled change and comparable rerun plus my personal contribution. I also state remaining limitations so the number is not interpreted beyond what was measured.

How did you build the workload model in your project?

I used approved analytics or explicitly stated assumptions to define arrivals or active users, operation mix, timing, data, payloads, and peaks. I mapped requests to business operations and validated achieved demand at the server. Any production difference remained documented as a limit.

Why did you select your performance testing tool?

I considered protocol support, team language, review workflow, existing libraries, data and correlation needs, execution mode, reporting, and migration cost. I can explain the alternative I rejected and its strengths. The workload and analysis method remain more important than the brand of tool.

What is the strongest bottleneck finding on your resume?

I start with the validated run and user-visible symptom, then correlate latency, throughput, errors, and relevant saturation on a timeline. I explain how evidence narrowed the hypothesis and how a controlled comparable experiment tested it. The answer includes outcome, tradeoff, and uncertainty.

How did you make a performance test safe?

I obtained authorization, agreed on schedule and demand limits, isolated third parties and data, set abort conditions, and rehearsed with smoke load. I monitored generators and the system throughout and had owners available. Cleanup, retention, and cloud cost were planned.

How do your performance tests run in CI?

I layer fast controlled checks per change and schedule representative workloads in suitable environments. Scripts, builds, configuration, data, baselines, and artifacts are versioned. A failure enters an owned triage path that distinguishes product, test, environment, and baseline rather than rerunning automatically.

How do you validate load-generator health?

I monitor CPU, memory, network, connections, scheduling, errors, and dropped work, then compare planned with achieved business operations. Distributed runs also require consistent configuration, data partitioning, time, and aggregation. A configured rate is not evidence that the target received it.

What would you improve in your performance portfolio?

I name a genuine limitation, such as narrow data distribution, one generator, short duration, missing traces, or a nonrepresentative environment. I explain how it constrains conclusions and propose the next controlled experiment. A specific limitation shows stronger judgment than claiming completeness.

How do you communicate a regression to developers?

I provide the objective, comparable baseline, workload, environment, validity checks, observation, and reproducible artifacts. I separate the observation from the suspected mechanism and work with service owners on a discriminating experiment. The final report includes improvement, tradeoffs, and remaining risk.

Why should we hire you as a Performance Test Engineer?

I connect business demand to reproducible system evidence and engineering decisions. My value is not only generating load, but validating the experiment, diagnosing across layers, and communicating limitations clearly. I support that answer with one concise measured project rather than a list of tools.

Frequently Asked Questions

How long should a Performance Test Engineer resume be?

One page can suit an early-career candidate, while two pages are reasonable for experienced engineers with relevant depth. Prioritize readable evidence over forcing a rigid length, and remove repetition or unrelated detail.

Which skills should be on a performance testing resume?

Include truthful skills relevant to the posting, such as workload modeling, k6, JMeter or Gatling, scripting, HTTP and APIs, SQL, Linux, observability, databases, containers, cloud, and CI. Group them clearly and prove the most important ones in experience bullets.

How do I write performance testing achievements without metrics?

Describe scope, action, technical mechanism, evidence, and the decision or risk affected. Use a qualitative result when no reliable number exists, such as enabling a release decision or isolating a retry mechanism, rather than inventing precision.

Can a fresher create a Performance Test Engineer resume?

Yes. Build a safe project against a service you control, with a documented objective, workload, data, checks, telemetry, baseline, controlled experiment, report, and limitations. Projects can prove the method when production experience is limited.

Should I include both JMeter and k6 on my resume?

Include both only if you have genuine hands-on evidence. Order skills according to the target role and use experience or projects to show depth rather than listing tools with no context.

How do I make a performance testing resume ATS-friendly?

Use standard headings, a simple single-column structure, real text, consistent dates, and accurate terminology from the posting. Match keywords to evidence and verify that the exported document preserves text and reading order.

What performance testing project should I put on GitHub?

Use a local or authorized service with a database and telemetry. Include reproducible setup, synthetic data, safe workloads, functional checks, generator validation, dashboards or queries, one controlled comparison, a report, and explicit limitations.
