We are seeking a hands-on Performance QA Engineer to help ensure our platform is fast, scalable and reliable under real-world load. In this role you will design and build performance tests using Grafana k6, establish the baselines and thresholds that define acceptable performance, and use our Grafana observability stack to explain why a system behaves the way it does.
You will work closely with engineers, product managers and DevOps to embed performance into the development lifecycle — contributing to shared standards, integrating performance checks into CI/CD, and giving teams an evidence-based view of release readiness.
Key Responsibilities
• Design, develop and maintain performance test suites using Grafana k6, covering load, stress and benchmark scenarios.
• Define thresholds and performance baselines from business and operational goals and detect regressions against those baselines.
• Contribute to test strategies, test plans and acceptance criteria alongside developers and product teams.
• Analyze results using the Grafana observability stack (Loki, Grafana,
Tempo, Mimir) — correlating metrics, logs and traces to identify bottlenecks and reach root cause.
• Build and maintain Grafana dashboards and alerts for performance signals.
• Integrate performance tests into CI/CD pipelines (GitHub Actions) so performance signal arrives early and is trusted.
• Create and execute manual and automated test cases where necessary to validate behavior under load.
• Identify, document and track defects, and follow through to timely resolution.
• Own test data management and workplace setup for performance runs.
• Report performance status, risks and actionable recommendations clearly to engineering peers and stakeholders.
• Contribute to the team's shared standards, scaffolds and playbooks, and advocate for performance as a first-class quality attribute.
Required Qualifications
• 3+ years of experience in software testing, QA engineering or performance en
