Senior🎓
Top SchoolWilliam Steffenhagen is a Pipeline SDET II and seasoned software test engineer with around a decade of experience delivering robust QA and automation solutions across regulated and eCommerce domains. He built test suites and frameworks from the ground up—automating 90% of FDA-focused test cases at Freenome using Python, PyTest, GKE, Pub/Sub and Flyte—and has deep hands-on experience integrating local containerized mocks for hard-to-reproduce scenarios. Comfortable across backend, API, and web automation stacks (Postgres, GCS, Selenium, Java, and modern CI/CD), he’s also mentored teams, reviewed cross-repo changes, and produced validation artifacts for regulatory submissions. Known for turning complex, flaky systems into reliable pipelines, he combines pragmatic engineering with a strong focus on traceability and continuous improvement. Based in Chico, CA, he brings both the discipline of regulated software testing and the flexibility of startup engineering to delivery-focused teams.
