About this role

We're looking for a Senior SDET to own quality engineering end-to-end. This is a greenfield opportunity — you'll define the strategy, choose the tools, and build the automation infrastructure from scratch. You'll work directly alongside our engineering team as the first quality engineer, so you need to be self-sufficient, opinionated, and driven.
This is an 70/30 role: 70% automation, 30% exploratory and manual testing.

What You'll Do

- Design and implement our QA strategy from the ground up

- Build and maintain automated test suites across API, UI, and integration layers

- Integrate testing into our CI/CD pipelines and own the quality gates

- Perform exploratory and manual testing on new features and releases

- Define quality metrics and report on them to the wider team

- Collaborate with engineers to improve testability at the design stage

- Leverage AI-assisted tools to accelerate test creation and coverage

What We're Looking For

• 5+ years in SDET, QA Engineering, or similar

• Strong hands-on experience with modern automation frameworks (Playwright, Cypress, REST Assured, or similar)

• Proficiency in Typescript and Python

• Experience building test infrastructure from scratch — not just inheriting existing frameworks

• Solid understanding of CI/CD and integrating tests into pipelines (GitHub Actions, GitLab CI, etc.)

• Familiarity with AI-assisted testing tools and an appetite to keep up with the space

• Comfortable working independently without a QA team around them

Nice to Have

- C# and/or Java experience is an advantage

- Experience with contract testing (Pact or similar)

- Performance testing exposure (k6, Locust)

- Accessibility testing awareness (WCAG, axe-core)

- Temporal.io experience
