About the role
The Job In Short

You combine deep technical expertise with mentorship, driving test automation, AI adoption, and a culture of quality ownership across your team.

- Automate Everything: Build and own the test infrastructure, coding robust automation for all acceptance suites within our CI/CD pipelines.
- Innovate: Implement AI-driven testing tools to accelerate test case generation and visual regression checks.
- Coach & Mentor: Guide engineers on TDD/BDD practices, ensuring the entire team writes high-quality, testable code.
- Quality Gatekeeper: Challenge requirements early to ensure they are unambiguous, complete, and fully testable before a single line of code is written.
How About You
- Tech Stack:.Senior-level proficiency in Java is mandatory, along with proficiency in at least one other language (Python or JavaScript), with the ability to code complex automation.
- Tooling Expert: Hands-on mastery of frameworks (Selenium, Playwright, Cypress) and CI/CD configuration (Jenkins, GitHub Actions).
- Methodology: Deep understanding of the SDLC, the V-Model, and how to define provable acceptance criteria.
- Forward-Thinking: Experience with or a strong desire to apply AI testing techniques to modern quality challenges.
- Mindset: A proactive collaborator who takes full ownership of domain quality and thrives on solving impediments independently.
