Research Engineer
Cursor is building the future of coding. We train frontier coding agents and scale RL on real user data to make them increasingly effective.
About the role
We’re looking for Research Engineers to build the training, inference, and data systems behind our frontier coding models. You’ll work directly with researchers to make progress repeatable and iteration fast.
What you might do
- Build our distributed training, inference, and RL infrastructure
- Write libraries to simplify how researchers do large-scale data jobs
- Architect the systems that turn Cursor user data into effective training data
You might be a fit if
- You have a strong infrastructure/distributed systems background
- You are able to architect and ship end-to-end with high ownership
- You have strong intuitions about how language models work
- You’re excited to learn more about ML
About
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.
Built to make you extraordinarily productive, Cursor is the best way to code with AI. Cursor is an applied team focused on building the future of coding. Agent turns ideas into code: A human-AI programmer, orders of magnitude more effective than any developer alone.
