Senior JMeter Engineer (8–10 years) 

• Own, refactor, and optimize Apache JMeter test plans (HTTP(S), WebSocket, JDBC, JMS) for core business journeys.
• Design realistic workload models based on production analytics (concurrency, think-time, arrival-rate, traffic mix).
• Plan and execute load, stress, soak, spike, and scalability tests; define pass/fail criteria aligned to SLAs/SLOs.
• Adopt and extend Grafana k6 where appropriate; standardize common libraries and thresholds across tools.
• Automate test execution in CI/CD (GiTLab/GitHub Actions/Jenkins/Ansible) with environment provisioning and artifacts publishing.
• Correlate results across APM/logs/infra metrics (Grafana/Prometheus/Elasticsearch /AppDynamics) to isolate bottlenecks.
• Champion NFRs (performance, reliability, resilience) and advise architecture on caching, connection pools, and capacity.
• Create executive and engineering-level reports with clear insights, trends, and remediation recommendations.
• Contribute to Synthetic User Monitoring by codifying critical API and UI probes and alert thresholds.

• 8–10 years in performance engineering with 5+ years deep expertise in Apache JMeter.
• Hands-on with Grafana k6 (scenarios, thresholds, checks, distributed runs).
• Strong scripting skills (Groovy/JS/Python/Bash) for parameterization, correlation (RegEx/JSONPath), and custom plugins.
• Proficiency analyzing server-side metrics: CPU, memory, GC, threads, connection pools; network and DB diagnostics.
• Experience with distributed load generation (on-prem), container-based runners, and test data strategies.
• Ability to translate business flows into performance test designs and to present insights to senior stakeholders.

Nice to Have

• Experience with Kubernetes/Helm-based test environments; service virtualization.
• Knowledge of resilience testing/chaos experiments and reliability engineering practices.
• Security/perf interplay (TLS, cipher selection), and browser-level RUM/Synthetic correlation.

Soft Skills

• Strong analytical thinking and methodical root-cause analysis.
• Excellent written and verbal communication; clear executive reporting.
• Mentoring mindset and collaborative approach with Dev, Ops, and QA.
