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.

Role

Infrastructure engineers build the platform that supports Cursor's functionality. Sometimes this means inventing highly-available distributed systems. Sometimes this means dealing with woes of scaling to millions of programmers.

Sample projects include...

  • Creating a retrieval system that processes 10,000,000,000+ files

  • Staring at esoteric flame graphs to performance engineer our reranking library

  • Working with many databases, proxies, caches, task queues, and orchestration systems

  • Shipping infra for safely computing import graphs and shadow lints
