Para ser considerado para una entrevista, por favor, asegúrese de que su solicitud se ajusta plenamente a las especificaciones del puesto que se encuentran a continuación.

As a Senior Quality Engineer, you’ll work independently to embed quality throughout the development lifecycle, not just validate it at the end. You’ll shift testing left — spotting risks before code is written, building validation into CI/CD, and making autonomous calls on risk, coverage, and release readiness — while coaching the wider team to raise their own testing practices and use AI tools effectively.

Key Responsibilities
- Drive validation strategy independently: what to test, at what level, and how — starting before development begins
- Define test scenarios covering key flows, edge cases, and risk areas; challenge non-functional requirements (performance, reliability, security)
- Build and maintain automated tests (API, integration,



end-to-end) running continuously in CI/CD
- Own release-readiness calls and post-release checks, using production signals (errors, logs, metrics) to close the loop
- Coach the team on testing practices, shared quality ownership, and effective use of AI tools
- Contribute to the wider Quality Engineering community and standards

Requirements
- 5+ years in Quality Engineering / QA, with experience defining validation strategy independently
- Strong systems thinking — able to spot risks and failure points across component interactions
- Experience with API testing (REST Assured, Postman), integration/E2E testing, and CI/CD-integrated automation
- Experience with performance testing (k6, JMeter)
- Comfortable working with minimal oversight and making risk trade-off calls
- Curiosity about AI-assisted testing tools

Nice-to-Have Skills
- Contract testing (Pact), Playwright, BDD, large-scale migrations
