Performance & Load Testing design, develop, and execute performance test suites using Gatling and/or Locust to validate system behavior under high-throughput, high-concurrency conditions

Automate build and maintain robust automated test frameworks using Python and PyTest, ensuring high coverage and fast feedback loops

Understand the Product proactively learn functional and business domain knowledge to independently create meaningful, well-targeted test cases that go beyond surface-level validation

Non-Functional Testing contribute to scalability, reliability, soak, and stress testing to ensure services meet production-grade SLAs

API Testing validate RESTful APIs for correctness, error handling, data integrity, and contract compliance

Debug & Investigate trace test failures across distributed services and cloud infrastructure; collaborate with developers on root cause analysis

Collaborate work closely with developers, product owners, and cross-functional teams to define acceptance criteria, identify edge cases, and shift quality left

CI/CD Integration integrate automated test suites into CI/CD pipelines for continuous quality validation

Report & Communicate produce clear test reports, defect analyses, and quality metrics; flag risks early and advocate for quality across the team

Document maintain test plans, test cases, and testing documentation to ensure traceability and knowledge sharing
