Job Description
About the Role:
We are looking for an experienced Senior Test Automation Engineer to join a cross-functional product team. In this role you will own the quality strategy across a modern, API-first product stack — designing test frameworks, driving CI/CD quality gates, and mentoring colleagues to raise the overall engineering bar. The split is approximately 30% front-end / 70% back-end testing.
What you will do:
- Plan and execute integration, system, and usability testing across the full product.
- Participate in end-to-end (E2E) and user acceptance testing (UAT) cycles.
- Collaborate closely with development teams to understand critical paths and maintain product stability.
- Build and maintain automated test frameworks for web, API, mobile, and performance testing.
- Drive CI/CD quality gates and own pipeline integration of test suites.
- Conduct code reviews and promote good programming practices within QA and Dev teams.
- Lead proof-of-concept and showcase activities when evaluating new tools and technologies.
- Mentor junior and mid-level engineers — sharing knowledge, reviewing work, and raising team standards.
- Foster a culture of quality and proactive problem-solving across engineering squads.
What we are looking for:
Minimum 5+ years of hands-on test automation experience.
Core technical skills:
- Proficiency in Java and/or JavaScript for test development.
- Strong expertise in Git and version control workflows.
- Hands-on experience with Postman for API testing and validation.
- Deep knowledge of CI/CD processes and tooling.
- Excellent understanding of API response structures and contract testing.
- Experience with performance testing methodologies and execution.
- Solid grasp of SDLC across the full software delivery lifecycle.
- Strong command of programming best practices: SOLID, KISS, OOP, design patterns.
- Experience in code review and promoting development standards.
- Proven ability to evaluate and integrate new tools and technologies (POC, showcase).
- Familiarity with Jira; experience with X-ray plugin is a plus.
