About the team
Automation Testing builds how developers test and automate their APIs, from local runs and CI pipelines to scheduled and large-scale runs in the cloud.
About the role
You'll work across Automation Testing, starting with API mocking and simulation. As a senior engineer, you're the lead for your area, and you own the engineering and the product together.
What you'll do
- Own your area end to end: decide what to build and why, then design, build and ship it across the app, backend and command line
- Work directly with customers: run quick experiments and prototypes, and turn what you learn into product and technical decisions
- Bring a point of view: write proposals, challenge assumptions and shape the roadmap with your peers
- Care about the details of the developer experience: UX copy, error messages, defaults and the first five minutes with the product
- Build the skills, agents and AI workflows that let developers and coding agents test and automate their APIs
- Make test runs fast, reliable and easy to debug, at any scale
- Mentor engineers and raise the bar for quality on the team
What we're looking for
- 6+ years building and shipping production software
- Experience leading an area as its technical owner, from design through delivery and quality in production
- A record of building customer-facing products, ideally for developers or other engineers
- Full-stack: strong TypeScript and React, working depth in backend services, and experience building CLIs or developer tools
- AI-forward: you use cutting-edge AI tools and coding agents every day to automate your work and operate at scale, and have built agents, skills or AI workflows into how a team works
Nice to have
- Experience with API mocking, service virtualization or contract testing
- Experience with API testing, developer tools or test automation
