Key Responsibilities

• Strong understanding of performance testing tools such as JMeter, LoadRunner, and Gatling.

• Convert NFRs/SLOs into measurable test objectives (throughput, p95/p99 latency, error budgets).

• Build realistic workload models including concurrency, think time, data mix, caching, spike/soak patterns, and canary strategies.

• Define environment parity and test data strategies to ensure credible results.

• Design scalable JMeter scripts with correlation, parameterization, data feeders, and custom logic (JSR223).

• Execute load, stress, spike, endurance/soak, capacity, and baseline tests across services and UI/API layers.

• Create reusable components/utilities to speed up authoring and reduce maintenance effort.

• Integrate performance suites into CI/CD pipelines (Jenkins/GitHub Actions) with automated thresholds and budgets.

• Establish performance release gates (pass/fail criteria, canary checks, rollback triggers) and lead go/no-go decisions.

• Publish and maintain the performance release checklist (warm-up, ramp-up, data hygiene, isolation, noise control).

• Leverage APM/observability tools (Grafana, Prometheus, Datadog, New Relic, Dynatrace, CloudWatch) to correlate metrics with test KPIs.

• Perform bottleneck analysis (CPU, GC, threads, DB query plans, caches, Kafka/queues, downstream dependencies).

• Produce clear performance reports with trends, variance against budgets, and actionable tuning recommendations.

• Validate environment configurations (instance types, autoscaling, TLS, caches) and eliminate client-side bottlenecks.

• Enforce warm-ups, steady-state validation, and repeatability, flagging any noise sources.

• Maintain baselines and flakiness detection for performance test results.

• Lead/mentor a small team when required (code reviews, coaching, establishing standards).

• Collaborate with Dev, DevOps, DBA, and SRE teams on triage, tuning, and verifying fixes.

• Drive post-release performance verification (canary checks, observability reviews) and participate in incident retrospectives.

Must-Have Qualifications

• 7–10 years of experience in performance engineering for web services and distributed systems.

• Strong, hands-on JMeter expertise (advanced correlation, JSR223 scripting, custom functions, backends/listeners).

• Solid knowledge of HTTP/REST, TLS, concurrency, caching, connection pooling, and asynchronous patterns.

• Proven experience integrating performance tests into CI/CD and enforcing SLO/threshold-based gates.

• Skilled with APM/observability tools and infra/DB analysis (GC, heap, thread dumps, slow queries).

• Scripting experience in Java, Groovy, or Python for utilities, data generation, and JMeter extensions.

• Strong communication skills with the ability to translate data into insights and influence release outcomes.

Nice-to-Have Skills

• Exposure to cloud platforms (AWS/GCP/Azure) and container environments (Docker, Kubernetes).

• Experience with protocols (gRPC, WebSocket) and Kafka throughput/latency testing.

• Strong understanding of DB performance (indexing, query plans, connection limits across MySQL/Postgres/NoSQL).

• Awareness of security–performance interplay (ciphers, WAF/CDN) and edge/CDN caching strategies.

• Experience with service virtualization and synthetic data platforms.

End-to-End Performance Release Ownership

You will:

• Define and enforce performance budgets through CI gates.

• Run canary performance checks and validate stability with live metrics before full rollout.

• Document go/no-go decisions with supporting evidence (APM dashboards, logs, charts).
