Lead QA Engineer
We’re looking for a QA Engineer to join our fast-moving engineering team at Stack AI in San Francisco. You’ll play a key role in ensuring the reliability, scalability, and usability of the platform that powers AI-driven workflows for thousands of users.
This is a hands-on role for someone who’s deeply curious about how things work, loves to break them (safely), and wants to help us deliver the most stable, polished version of Stack AI possible. You’ll work closely with engineers, product managers, and designers to test features, build automated QA systems, and shape our quality culture from the ground up.
What You’ll Do
You’ll be the first dedicated QA hire, setting the foundation for automated testing, release validation, and reliability metrics across the entire product surface.
Test Planning & Execution
Design, write, and execute test plans for new features across web, API, and backend systems.
Develop and maintain automated test suites (unit, integration, end-to-end) for a modern TypeScript + Python stack.
Run regression and performance tests before major releases.
