# Test Harness Engineer

We're looking for a Test Harness Engineer to join a client product team and design and build the testing systems that protect the quality of a growing technology platform. This role goes beyond writing test scripts: you will build AI-powered test harnesses where agents help plan, execute, validate, and analyze testing activities. You'll combine strong software engineering with automation, exploratory testing, and a product-oriented mindset. You'll collaborate closely with engineering and product teams in a fast-paced environment where quality is a shared responsibility and continuous improvement is highly valued. You will make architecture and tooling decisions and take ownership of quality from design to release. Responsibilities: Design and extend AI-powered test harnesses where agents plan, execute, validate, and analyze test scenarios. Integrate LLMs (OpenAI, Claude, Gemini, or similar) with tools, APIs, and automation frameworks, with evaluation and guardrails to prevent false positives. Build and maintain automated UI, API, and integration test suites that run reliably in CI/CD pipelines, keeping them fast and maintainable. Turn Jira acceptance criteria and Figma designs into
