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

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 securityperformance 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).
