Software Developer

About This Role We are looking for a Software Developer with 3-4+ years of experience to join a 3-person team building AI-powered CAD software that is creating a foundation model for mechanical engineering. You'll be a curious, ownership-driven engineer who can pull their own weight and ship production code end-to-end. This is a ground-floor opportunity at a YC-backed startup that has answered its fundamental technical questions and is now pouring gasoline on the fire, the team is doubling in the next few months. The founders were early employees (first 10) at Cruise Automation (acquired by GM for $1B+) and are recreating that kind of magic. What Will You Be Doing? Design, develop, and maintain robust backend systems in Python, interfacing with existing CAD software on desktop platforms (Mac OS/Windows) Own features end-to-end from concept through production — building data pipelines, backend components, and shipping code at startup speed Collaborate directly with the CTO and founding engineer to define architecture and ship new features rapidly Make pragmatic trade-offs between code quality and speed, understanding technical debt and knowing how to address it later
