Product Engineer

Recruiting From Scratch•San Francisco, CA

3d•Onsite

About The Position

The Product Engineer will build the customer-facing product for an early-stage company developing AI-powered engineering simulation technology. The platform uses physics foundation models and proprietary model architecture to help engineers perform complex simulations and analyze results faster than traditional numerical methods. Its applications span areas including automotive, energy, and other industrial sectors. Working directly with researchers and the founding team, the Product Engineer will turn advanced research into practical, reliable software for engineering teams. This is a high-ownership, hands-on role spanning frontend interfaces, APIs, backend services, and data systems. The engineer will take product features from requirements and technical design through implementation, deployment, and ongoing production improvements, including workflows for importing CAD and 3D geometry, configuring model jobs, running simulations, and visualizing results. The position is full-time and on-site in San Francisco five days per week. The company is early-stage and pre-seed, with five openings. The stated ideal experience is approximately 5–8 years; candidates with 2–3 or more years may be considered, and candidates with up to approximately 15 years may also be considered. Base salary is $180,000–$250,000, depending on experience and skills, with a competitive equity package. The company is open to active, transferable work authorization, including eligible OPT and H-1B transfers; U.S. citizens and permanent residents are preferred for certain customer engagements.
