About

We're Anysphere, the team behind Cursor.

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.

We're a group of engineers and scientists who've built beloved products, created large OSS projects, started at-scale businesses, won olympiad medals, and published significant research (e.g. tmm1, ian, luke, phil, federico, aman, sualeh).

Our organization is very flat, and our team is small and talent dense. We particularly like people who are truthseeking, 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. Our investors include Andreessen Horowitz, OpenAI, Jeff Dean, John Schulman, and the founders of Stripe and Github.

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.
