Senior Engineer - QA

• Test Automation: Design, develop, and maintain scalable automated test suites using Python and frameworks such as Robot Framework, PyTest, and Playwright.
• API Testing: Own automation for REST APIs, including functional, integration, contract, negative, authentication, and end-to-end scenarios.
• Performance and Load Testing: Design, develop, and execute performance, load, stress, and endurance tests to evaluate application behaviour under varying workloads.
• Performance Test Scripting: Build and maintain reusable performance test scripts using tools such as Locust, JMeter, or k6, with a strong emphasis on code-driven performance testing.
• Performance Analysis: Analyse response times, throughput, error rates, resource utilisation, and latency percentiles to identify bottlenecks and performance degradation.
• Root Cause Investigation: Collaborate with developers and infrastructure teams to investigate performance issues across APIs, services, databases, and distributed systems.
• Performance Benchmarking: Establish performance baselines, define measurable acceptance criteria, compare results across releases, and identify regressions before production deployment.
• CI/CD Integration: Integrate functional automation and performance smoke tests into CI/CD pipelines, enabling early detection of regressions and faster feedback.
• Framework Engineering: Improve automation framework architecture, reusable libraries, test data management, parallel execution, reporting, and test reliability.
• Test Strategy and Planning: Define test coverage and approaches for new features, identify quality risks early, and determine appropriate functional and non-functional testing requirements.
• Troubleshooting and Debugging: Investigate complex failures using application logs, API traces, monitoring dashboards, and performance test reports.
• Code Reviews and Mentoring: Review automation code, promote coding standards, share technical knowledge, and support the development of junior engineers.
• Quality Reporting: Communicate test coverage, automation health, performance trends, bottlenecks, and release risks through clear, actionable reports.
• Cross-functional Collaboration: Work closely with developers, product managers, DevOps, and US-based engineering counterparts to align on quality goals and delivery priorities.

• Bachelor's degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience.
• 4–8 years of hands-on experience in software testing and test automation, including substantial experience with API automation.
• Strong programming skills in Python or Java, with the ability to develop clean, reusable, and maintainable test code.
• Strong hands-on experience with at least one automation framework, such as Robot Framework, PyTest, or Playwright.
• Solid understanding of REST APIs, HTTP protocols, authentication, schema validation, and integration testing.
• Strong practical experience in performance and load testing, including designing workloads, executing tests, interpreting results, and investigating performance bottlenecks.
• Hands-on experience with at least one performance testing tool such as Locust, Apache JMeter, or k6.
• Understanding of key performance metrics, including response time, throughput, requests per second, error rate, concurrent users, and p90/p95/p99 latency.
• Experience analysing performance test results and correlating application behaviour with logs, monitoring metrics, database activity, or infrastructure resource utilisation.
• Experience integrating automated tests into CI/CD pipelines using tools such as GitHub Actions, Jenkins, GitLab CI, or equivalent.
• Proficiency with Git, including branching, pull requests, and code review workflows.
• Strong analytical, debugging, and problem-solving skills, with the ability to work independently and take ownership of deliverables.
• Good written and verbal communication skills, including the ability to explain technical findings to cross-functional stakeholders.
• Willingness and availability to attend regular meetings with US-based counterparts during evening hours in India, depending on team and project requirements.
• Ability to work onsite in Bengaluru.
