testspriteSeattle (WA)
About the role
Be the technical lead for the AI agents that test software, whether people or AI coding tools wrote it. You'll own the architecture, write the hardest code, and help decide what we build next.
Code now ships faster than anyone can review it, and we're building the layer that checks it. TestSprite plugs into Cursor, Windsurf, Claude Code and other coding agents through our MCP server and CLI, and it runs in CI. More than 100,000 users rely on TestSprite, from solo developers to enterprise engineering teams. We're backed by Trilogy Equity Partners, Techstars, Hat-Trick Capital, Jinqiu Capital, MiraclePlus, Baidu Ventures and EdgeCase Capital Partners.
The role:
This is a hands-on IC role with tech-lead scope. You'll own the architecture of our agent platform, from how tests get planned to how they run, get judged and repair themselves. You'll set the technical bar for the team and work directly with the founders.
What we're looking for:
5+ years building production software Deep understanding of AI and LLMs Strong algorithms and CS fundamentals Strong system architecture skills Strong product sense You iterate fast Great technical taste Passion for AI developer tools Experience with software testing
Compensation
Top-of-market pay and meaningful equity.
TestSprite is an equal opportunity employer.
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
