• Build and maintain service-level (unit + integration) automated tests for TypeScript/Node.js services
• Develop cross-service integration tests to validate APIs, contracts, and workflows
• Create and evolve reusable automation frameworks for backend and API testing
• Integrate tests into CI/CD pipelines to provide fast, reliable feedback
• Collaborate with engineers to embed testing into the development lifecycle
• Identify gaps in coverage and drive improvements in system reliability
• Troubleshoot flaky tests, distributed system issues, and test environment challenges

Requirements

• 4+ years of experience in an automation-focused role (SDET, QA Automation Engineer, or similar)
• Strong experience testing backend systems and microservices architectures
• Proficiency in TypeScript/JavaScript and experience with Node.js services
• Working knowledge in Postman API
• Hands-on experience with automation tools/frameworks (e.g., Jest, Mocha, Playwright, Supertest, or similar)
• Experience with API, integration, and contract testing (e.g., Pact or similar)
• Familiarity with CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI, etc.)
• Solid understanding of distributed systems (service dependencies, retries, eventual consistency)
• Ability to operate independently and take ownership of ambiguous problems
