• Design, modify, and optimize performance tests using J-Meter, Gatling or similar tools (Intermediate to Expert level).
• Create comprehensive performance test strategies, test plans, workload models, and execution frameworks for complex distributed systems.
• Identify root causes of performance issues, guide development teams to fix those rather than their symptoms.
• Execute and oversee performance, load, and benchmark tests; provide timely analysis and status reporting during active release cycles.
• Publish comprehensive performance test reports and communicate findings to DevOps and development teams for triage and resolution.
• Support team management in prioritizing backlog items.
• Translate business requirements to user stories and actively seek feedback from stakeholders.

• Expert-level performance engineering execution experience with demonstrated ability to lead performance initiatives.
• Demonstrated leadership in pushing teams towards better quality software and helping team members develop simpler, more robust test designs.
• JMeter, Gatling, Taurus, or similar load/performance testing tools: Intermediate to Expert.
  • Design, modify, and maintain complex performance test scripts.
  • Experience with BlazeMeter (or similar) as an execution/orchestration platform for test runs and result analysis.
• Java code comprehension for performance analysis: Intermediate.
  • Create performance test scenarios aligned to application behavior.
  • Understand why specific code patterns can cause performance issues.
• Appium/Selenium for UI performance testing.
• SQL and database performance tuning: Intermediate to Expert.
  • Prevent slow queries and optimise SQL for faster execution.
  • Identify bottlenecks, including locking/contention.
  • Recommend query improvements and indexing strategies.

  • Understand use cases when to use one vs other with implementation examples.
• JVM fundamentals: Intermediate.
  • Memory leaks: what they are and how to troubleshoot.
  • Garbage collection (GC) impact on latency and throughput.
  • Optimize JVM configurations for improved application performance.
  • Conduct heap dump analysis and performance profiling.
• Observability and monitoring tools: Intermediate (hands-on).
  • Practical experience with Elastic/Splunk/Datadog (or equivalent).
  • Ability to query application logs in Elastic/Kibana and write KQL (or equivalent queries).
  • Extract and analyze information related to performance (memory, CPU, latency, throughput, etc.).
  • Correlate application logs with performance metrics to identify root causes.
  • Create dashboards and alerts for proactive performance monitoring.
• Tools Familiarity: Linux, Jira, Git, GitHub, Jenkins, GitHub Actions, IntelliJ/Eclipse, SSMS.
