About The Position

We're hiring our first dedicated SDET to own test automation across our product suite. 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.

Requirements

4+ years in test automation, SDET, or software engineering roles with a strong testing focus
Strong C#/.NET skills — you write production-quality test code, not just record-and-playback scripts
Hands-on experience with modern UI automation frameworks (Playwright, Selenium, or similar)
Experience building API-level test suites (REST, integration testing, test data management)
Experience wiring test automation into CI/CD pipelines
Comfort using AI tools (Claude, Copilot, or similar) as a core part of your workflow — or strong enthusiasm to adopt them
Self-directed and comfortable owning a domain on a small team

Nice To Haves

Experience testing Blazor applications (bUnit, Playwright against WASM apps)
Mobile automation experience (Appium, .NET MAUI UI testing, or similar)
Experience testing authentication/authorization flows (OAuth, OIDC)
Healthcare or other regulated-industry experience; familiarity with HIPAA and handling PHI in test environments
Performance or load testing experience
Experience with Azure DevOps pipelines specifically

Responsibilities

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.
