Senior Software Engineer

About the role

We are looking for Senior to Staff Software Engineers for a Series-A AI startup which companies use to run their business on agents.

About the role

We’re looking for unusually strong engineers, from mid-level to Staff+, to build across three areas:

Product: The experiences through which people use across our web and mobile apps, website, onboarding, and everything else our users touch—making powerful agents feel simple, fast, trustworthy, and delightful.

Platform: The backend APIs behind product features; accounts, workspaces, permissions, billing, payments, and analytics; and the connector, authentication, webhook, and automation infrastructure.

AI Infrastructure: The core machinery that makes agents capable, reliable, efficient, and scalable, including our agent harness, context management, filesystem, and execution environment, as well as model serving, databases, Kubernetes, networking, and cloud infrastructure.

Who you are

You've 2+ years of experience shipping production TypeScript full- stack, with backend/infra ownership

You’re an exceptional problem solver with strong computer-science fundamentals.

You reason from first principles, form clear mental models, and see how parts interact within a larger system.

You’ve shipped meaningful, high-quality production software and owned it after launch. You can debug a problem wherever it leads.

You care about both clean design and real outcomes, whether that means product craft, performance, correctness, security, reliability, safety, cost, or operational simplicity.

You learn quickly, operate well with ambiguity, and prefer responsibility over process.

You use AI deeply in your own work. We don’t require prior professional AI experience, but we do expect you to already be seriously engaged: using current models, probing their limits, following the field closely, and forming your own views about where AI systems are going and how they should work.
