Technical Requirements (Tech Stack)

  1. Performance Testing Tools
  • Expertise in JMeter: Advanced scripting, custom samplers, and Groovy/BeanShell scripting.
  • Expertise in LoadRunner: Proficiency in Web HTTP/HTML, TruClient, and Web Services protocols.
  • K6 or Gatling: (Optional/Plus) Experience with modern "as-code" performance tools.
  1. Observability & Monitoring
  • APM Tools: Hands-on experience with Dynatrace, New Relic, or AppDynamics to monitor transaction snapshots and code-level hotspots.
  • Infrastructure: Ability to analyze metrics in Prometheus & Grafana.
  • Log Management: Proficiency in searching and visualizing logs via ELK Stack (Elasticsearch, Logstash, Kibana) or Splunk.
  1. Systems & Infrastructure
  • Architecture: Deep understanding of Microservices, Load Balancers (NGINX/F5), and Caching layers (Redis).
  • Cloud & Containers: Familiarity with Docker & Kubernetes (K8s) monitoring (pod health, resource limits).
  • Databases: Ability to identify slow queries and understand indexing in PostgreSQL, MySQL, or Oracle.
  • Workload Modeling: Analyze production usage patterns (via Google Analytics or logs) to create realistic performance test scenarios.
  • End-to-End Testing: Design and execute Load, Stress, Endurance, and Scalability tests.
  • Bottleneck Diagnosis: Analyze Thread Dumps, Heap Dumps, and Garbage Collection (GC) behavior to identify memory leaks or locking issues.
  • Shift-Left Performance: Integrate performance tests into CI/CD pipelines (Jenkins, GitLab, or Azure DevOps) for automated performance gating.
  • Capacity Planning: Provide recommendations on hardware/cloud resource scaling based on test results.

Soft Skills & Qualifications

  • Analytical Mindset: You don't just report "the system is slow"; you find out which line of code or which database query is the culprit.
  • Communication: Ability to explain complex technical bottlenecks to non-technical stakeholders.
  • Experience: 3+ years in Performance Testing/Engineering or Software Development.
