You'll design, build, and maintain automated test suites that act as a continuous QA layer for our web, API, and mobile applications. This is a high-ownership role on a small, senior onshore team - your work directly determines how confidently we ship. A defining feature of this role: we are an AI-forward engineering organization. We use Claude Enterprise heavily across our SDLC, and you'll leverage it daily to author, update, and maintain test scripts at a pace a traditional QA process can't match. We're looking for someone who is energized by that way of working, not resistant to it., * Own end-to-end test automation for our Blazor WebAssembly front end, including UI and functional test suites (e.g., Playwright). * Build and maintain API test coverage for our .NET Core back-end APIs, Azure Function apps, and dedicated authentication service - integration, contract, and regression testing. * Establish mobile test automation for our .NET MAUI mobile application across iOS and Android. * Leverage Claude Enterprise to generate, refactor, and maintain test scripts efficiently, and help define best practices for AI-assisted testing on the team. * Integrate testing into CI/CD so automated suites run on every build and release, with clear pass/fail signals and actionable failure reporting. * Track and report quality metrics - escaped defects, coverage, flaky test rates - and use them to drive improvement. * Partner with developers to make testability a first-class concern in design and code review, and to reproduce, isolate, and verify bug fixes. * Perform targeted exploratory testing where automation isn't the right tool, especially for new features and edge cases. ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [Why you must use TDD now!](https://www.wearedevelopers.com/videos/114-why-you-must-use-tdd-now) - [Accessibility Test Driven Development](https://www.wearedevelopers.com/videos/1578-accessibility-test-driven-development) - [Advanced Cypress: custom assertions and tasks](https://www.wearedevelopers.com/videos/790-advanced-cypress-custom-assertions-and-tasks) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 119 - ❤️ === ❤️](https://www.wearedevelopers.com/magazine/454-dev-digest-119) - [WeAreDevelopers Dev Digest Issue 116 - The new search wars…](https://www.wearedevelopers.com/magazine/445-wearedevelopers-dev-digest-issue-116-the-new-search-wars)
