Senior SDET / Test Automation Engineer (TypeScript)‍

About the Role

We are looking for an engineer who sees testing as a code-first discipline. We are building a modern engineering culture where tests live alongside the code — not in isolated QA silos.

• Improve Developer Experience by creating fixtures, mocks, and helpers for local testing
• Integrate quality gates into GitLab CI pipelines to ensure fast and reliable feedback
• Mentor engineers on testing best practices and writing testable code

Requirements‍

• 3+ years of experience building automation frameworks from the ground up
• Strong TypeScript expertise (generics, interfaces, strict typing)
• Experience with modern automation patterns (Page Object Model, Screenplay, Composition)
• Solid understanding of API and backend testing (REST, GraphQL, microservices)
• Experience with Docker and debugging CI/CD pipelines
• Proactive mindset focused on preventing bugs through better tooling and engineering practices

Nice to Have‍

• Experience with Contract Testing
• Understanding of frontend and backend frameworks beyond testing — knowledge of how they work internally

We offer excellent benefits, including but not limited to‍

• Learning and development opportunities and interesting challenging tasks;
• Relocation package (tickets, staying in a hotel for up to 2 weeks, and visa relocation support for our employees and their family members).
• Partial compensation for tennis lessons.
• Opportunity to develop language skills and partial compensation for the cost of language classes;
• Transport compensation - 300 euros net per month.
• Time for proper rest, with 24 working days of annual vacation and additional paid sick days.
• Competitive remuneration level with annual review.

If you are passionate about building quality at the foundation level and shaping engineering culture, we would love to hear from you.
