Responsibilities: 

  • Partner with Agile feature teams to understand user stories, define acceptance criteria, and promote a test-first mindset through collaboration in design and refinement sessions.
  • Build, maintain, and evolve test automation frameworks using Playwright (preferred), TypeScript, or other enterprise-approved tools to support API and UI testing.
  • Drive the transition from legacy frameworks (e.g., Selenium + Java, Postman/Newman) to unified automation aligned with our CI/CD strategy.
  • Collaborate with developers and QA engineers to ensure test cases are executed in CI pipelines and provide fast, actionable feedback.
  • Support feature teams with manual testing efforts when needed, including test case design, exploratory testing, and validation of complex workflows that are not yet automated.
  • Develop and maintain automated API tests (REST/SOAP) and end-to-end tests that validate functional and non-functional requirements.
  • Participate in code reviews and contribute to test architecture decisions to ensure reliability, reusability, and scalability of test assets.
  • Write and maintain SQL queries to validate data integrity and support test data creation strategies.
  • Serve as a quality engineering champion—helping guide automation strategy, mentoring peers, and contributing to continuous improvement of QA practices.
  • Ensure traceability between requirements, tests, and defects, and support compliance with enterprise policies (e.g., HIPAA, security, audit readiness).

Experience: 

  • 5+ years’ experience of experience in application testing and test automation of web-services (REST/SOAP) and three years of Java and J2EE development skills with strong understanding of Java APIs, J2EE web components and containers.
  • Hands-on experience with Playwright (TypeScript preferred) or similar frameworks like Cypress or Puppeteer.

  • Familiarity with test reporting, dashboarding, and quality metrics in a DevOps environment.
