Core Responsibilities

Primary Functions

  • Design, implement, and maintain robust automated test suites for web, mobile, and backend services using industry-standard tools and frameworks (for example Selenium, Cypress, Playwright, Appium, JUnit, TestNG, pytest), ensuring tests are reliable, maintainable and run as part of CI/CD pipelines.
  • Own test strategy and test plans for feature releases and major product initiatives, defining acceptance criteria, risk-based testing approaches, and coverage goals aligned with product and business priorities.
  • Develop and execute automated API and integration tests (REST, GraphQL, gRPC, SOAP) using tools like Postman, REST Assured, Newman, or custom frameworks to validate service contracts and detect regressions early.
  • Integrate automated tests into CI/CD pipelines (Jenkins, GitLab CI/CD, GitHub Actions, CircleCI, Azure DevOps), ensuring deterministic results, parallelization, flaky test handling, and clear pipeline gating for deploys.
  • Lead end-to-end regression testing efforts and maintain a prioritized regression suite that balances fast feedback with comprehensive coverage for critical user journeys.
  • Implement performance, load and scalability testing (JMeter, Gatling, k6, Locust) to validate system behavior under expected and peak conditions, analyze bottlenecks, and work with engineering to remediate issues.
  • Collaborate with product managers, software engineers, UX designers, and support to translate user requirements and edge cases into test scenarios, acceptance criteria and measurable quality goals.
  • Drive test data strategy and management, including synthetic data generation, anonymized production-like datasets, database state setup, and test environment orchestration for reliable repeatable testing.
  • Perform root cause analysis on defects and production incidents, author clear technical defect reports, streamline triage workflows, and maintain a lessons-learned backlog to reduce recurrence.
  • Design and implement observability for test runs (logs, metrics, screenshots, video capture for UI tests) and integrate test results with reporting dashboards (e.g., TestRail, Allure, Xray) for traceability and SLA tracking.
  • Create and maintain a test automation framework or contribute to shared frameworks (framework libraries, reusable helpers, test harnesses) to accelerate onboarding and reduce duplicated effort.
  • Evaluate, recommend, and pilot new test tools and technologies (commercial or open-source) that improve test coverage, reliability, speed or developer experience.
  • Enforce quality gates and release criteria across staging and production promotion, including automated smoke tests, canary validations, and rollback triggers.
  • Mentor and coach engineers and QA peers on test-first approaches, TDD/BDD practices (Cucumber, SpecFlow), and writing maintainable automated tests that developers can own.
  • Participate in sprint ceremonies (planning, grooming, retrospectives) to raise quality risks early, prioritize testing work, and ensure test tasks are estimable and tracked.
  • Manage flaky test detection and remediation programs, using test stability metrics and retriage processes to keep pipelines healthy and minimize false positives.
  • Ensure compliance with regulatory and security requirements by embedding relevant tests (data privacy, encryption, access control) and participating in audits or compliance reviews.
  • Collaborate with DevOps to provision and maintain test environments, containerized test runners (Docker), and ephemeral environment practices to increase parallel testing throughput.
  • Monitor and report quality metrics (defect density, escape rate, mean time to detect, test coverage trends) to stakeholders, propose corrective actions, and measure improvements over time.
  • Lead manual exploratory testing sessions for complex workflows and edge cases that are not easily automated, capturing issues and converting critical scenarios into automated tests.
  • Coordinate cross-team end-to-end testing across microservices, third-party integrations and external partners to validate contracts, retries, and failure modes.
  • Own the lifecycle of test artifacts: test plans, test cases, automated scripts, results, and release sign-off documentation to ensure auditability and reproducibility.
  • Design and run security-oriented checks and collaborate with security teams for vulnerability scanning and penetration testing integration into the release pipeline.
  • Support incident response: reproduce production bugs, produce test cases that prevent recurrence, and support post-mortem corrective actions and monitoring improvements.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Train and evangelize quality best practices across product, customer success, and support teams to reduce friction and improve customer experience.
  • Assist in vendor evaluation and management for third-party test tools or outsourcing of test execution when required.
  • Provide on-call rotation support for test infrastructure and critical release support windows.
