Full posting

Original listing.

Our mission is to automate coding. The first step in our journey is to build the best tool for professional programmers, using a combination of inventive research, design, and engineering. Our organization is very flat, and our team is small and talent dense. We particularly like people who are truth-seeking, passionate, and creative. We enjoy spirited debate, crazy ideas, and shipping code.

We're in-person with cozy offices in North Beach, San Francisco and Manhattan, New York, replete with well-stocked libraries.

About the Role

Product engineers create the software we ship to our users, in particular our editor. As a member of our core product team, you'll join us in inventing a new, better way to build software.

You may be a fit if

  • You've built a great product.

  • You blend excellent engineering with a taste for models and design.

  • You have a propensity for creative ideas and have a knack for making powerful tools without compromising their ease-of-use.

Sample projects include

  • Inventing new interfaces and UX for reviewing PRs of AI-generated code

  • Sprinting for two weeks to build a new product vertical from scratch (e.g., AI bug detection)

  • Running experiments and A/B tests on millions of users to push the frontier of agent quality - ex sub-agents, memories, and PR retrieval

Applying

If there appears to be a fit, we'll reach to schedule 2-3 short technicals. After, we'll schedule an onsite in our office, where you'll work on a small project, discuss ideas, and meet the team.
