Tests running in CI/CD, ideally GitHub Actions.
Hands-on experience with AI, or active study of it, applied to testing workflows.
Good TypeScript/JavaScript skills.
Advanced English, written and spoken: you’ll work daily with the US team.
A product mindset: you think about the user, not just the test case.

Responsibilities

Design, write and maintain automated tests for REST APIs, web apps and React Native mobile apps.
Build integration/E2E tests that validate the API first, then confirm the result in web and mobile.
Write web E2E tests with Playwright (TypeScript).
Run cross-browser and real-device testing on BrowserStack.
Build Postman API collections and run them in CI.
Integrate test suites into GitHub Actions, with clear reporting and quality gates.
Use AI tools to generate test cases, refactor automation, triage flaky tests and analyze failures.
Shape test strategy and coverage with developers, product and design, starting early at the acceptance criteria stage.
