Software Engineer, ML Research

<p style="min-height:1.5em">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.</p><h1>Research Engineer</h1><p style="min-height:1.5em">Cursor is building the future of coding.
