About The Role
You will be responsible for ensuring quality across a live-chat product that provides an HTTP REST API and a WebSocket interface on the back end, while delivering functionality to end users through an embeddable JavaScript widget.

Responsibilities
- Audit and systematically replace existing manual test cases with automated equivalents.
- Design and maintain an integration test suite covering:
- HTTP API (request/response contracts, authentication, error handling)
- WebSocket behaviour (connection lifecycle, message delivery, reconnection handling)
- Build and own a stress/load testing framework to validate the system under realistic load conditions.
- Write end-to-end tests for the embeddable JS widget, including initialization, DOM injection, cross-browser compatibility, and behaviour across host-page environments (CSP restrictions, conflicting global, various frameworks).
- Write end-to-end and functional tests for the back-office agent application, covering core support workflows, real-time chat updates, and role-based access.
- Define and track quality metrics such as test coverage, defect escape rate, and mean time to detect.
- Integrate tests into the CI/CD pipeline so failures block deployments, with DevOps support from team members.
- Introduce contract testing to prevent breaking API changes from affecting production clients.
- Collaborate with the tech team to improve testability of C# services (mocking seams, structured logging, etc.).
- Triage and reproduce production bugs, adding regression tests before closing issues.
- Maintain test environments and manage test data strategies (isolated tenants, deterministic chat histories).
- 4+ years of experience in QA or software testing, with strong automation skills and experience testing web applications and APIs.
- Proven experience automating API tests (REST + WebSocket).
- Experience with load/stress testing tools.
- Strong JavaScript proficiency for testing and debugging embedded widgets and front-end applications.
- Experience with browser automation for end-to-end testing.
- Familiarity with CI/CD systems (GitLab CI, GitHub Actions, or similar).
- Ability to read and reason about C# code.
- Experience testing embeddable or third-party scripts in hostile page environments (CSP, ad blockers, framework conflicts).
- Familiarity with contract testing tools such as Pact.
- Experience with technologies/platforms such as AWS, Pulumi, Vue.js, LLMs, BDD, or TDD.
- Join us in shaping the future of customer support.
- Work alongside dedicated experts who share your passion and enthusiasm.
- Enjoy the flexibility of working remotely from anywhere in Europe.
- Take advantage of opportunities to learn, grow, and develop your career.
