We're looking for a QA Engineerto join our Tallinn QA team. This isn't a checkbox-testing role. You'll be diving deep into complex systems, hunting down elusive bugs, and building automation that makes the whole team faster.

What you'll do:

You'll work shoulder-to-shoulder with developers, product managers, and QA engineers to validate new features, investigate issues, and scale automated test coverage using Playwright and TypeScript. Day to day, that means:

• System-level verification across backend services, APIs, web interfaces, and device integrations.

• Planning, executing, and reporting on testing activities to keep releases sharp.

• Investigating complex behaviour by digging into logs, data flows, and system responses.

• Supporting validation in real-world environments that mix software with physical hardware.

• Basic understanding of test automation principles and workflows

• Spotting risks early and keeping production environments stable.
• Experience using AI tools in day-to-day work.

What you'll bring:

• Solid QA experience across complex, multi-component systems.

• Understanding of how test automation works and familiarity with automation frameworks (Playwright, Cypress, Selenium, or similar).
• Experience working with AI tools in testing and day-to-day tasks.

• Confidence testing APIs, backend services, and databases (PostgreSQL experience is a plus).
• Ability to debug issues by reading logs and tracing system behaviour - not just reproducing them.
• Clear communication and a collaborative approach across technical and product teams.

Bonus points forexperience withAFC/AVL systems, hardware/software systems, real-time or IoT environments, or transportation platforms.
