Software Engineer, ML Research

Software Engineer, ML ResearchEngineering · Full-time · San Francisco; New YorkOur 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.Research EngineerCursor 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 RoleWe'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'll DoBuild our distributed training, inference, and RL infrastructureWrite libraries to simplify how researchers do large-scale data jobsArchitect the systems that turn Cursor user data into effective training dataYou May Be a Fit IfYou have a strong infrastructure/distributed systems backgroundYou are able to architect and ship end-to-end with high ownershipYou have strong intuitions about how language models workYou're excited to learn more about ML
