Databricks

Role
Software Engineer (Contract)
Season
March 2026 – June 2026
Location
Berkeley, CA
Field kit
Python · Pytest · Playwright · Databricks SDK · Delta

Databricks’ Partner Demo Catalog ships 169 enterprise AI/ML partner solutions, and every one used to be verified by hand. I built the testing infrastructure that automates it. It runs Pytest, Playwright, and the Databricks SDK in a modular two-layer architecture: browser automation for user flows, extensible backend validation for 12+ resource types, 350+ tests in all. Results stream to a Delta table after every run, which turned verification into CI/CD and caught 36+ production issues before partners ever saw them. Verification time dropped 94%.
