QA Engineer

• Architect and lead enterprise-grade performance testing frameworks across multiple distributed systems, APIs, SDKs, and service integrations.
• Design, execute, and interpret performance, load, soak, and stress tests that simulate real-world concurrency and traffic behaviors.
• Build reusable performance harnesses using modern tools such as JMeter, k6, Gatling, Locust, or LoadRunner Enterprise, and integrate them into CI/CD pipelines.
• Author and maintain the Performance Testing Runbook — a detailed operational guide covering environment setup, load profiles, KPIs, and performance sign-off criteria.
• Instrument systems for observability, leveraging APM and monitoring tools (Datadog, New Relic, Grafana, Prometheus, ELK, OpenTelemetry) to trace and correlate test results with backend telemetry.
• Perform deep-dive bottleneck analysis at every layer of the stack — network, API, cache, database, and compute — identifying contention, saturation points, and tuning opportunities.
• Work directly with backend, DevOps, and SRE teams to benchmark system capacity, analyze regressions, and validate optimization hypotheses.
• Integrate performance metrics into CI/CD, enforcing data-driven go/no-go gates and providing clear visual reports on trend lines and performance drift.
• Mentor and influence QA, automation, and infrastructure engineers in the art and science of performance engineering.
