Job description

Aerospace Simulation Engineer - Physics Simulation Startup - Up to $250k base + equity

Get in early at the company building the OpenAI for physics.

This is a rare chance to join a startup at the stage where your fingerprints are on everything. You are not coming in to maintain someone else's work. You are helping to define how physics simulation gets done and will run CFD simulations at scale to generate the data that trains the foundation models, working directly with the CEO and founding team.

Day to day, you are working on aerothermal and hypersonic flow problems, developing and refining physics models that actually get used by real clients. You are working closely with a tight, collaborative team where your input shapes the direction of the work. There is no bureaucracy slowing you down and no politics getting in the way. Just hard problems, smart people, and the freedom to do your best work.

The company is early stage and growing fast. The backing is prominent and the trajectory is clear. Coming in now means you are not just an employee, you are part of the foundation. On top of a base salary, you get a strong equity package and standard benefits. This is the kind of opportunity where the upside is real, not just a line in a pitch deck.

Your background is in CFD and simulation, with solid industry experience behind you. You know aerothermal environments and hypersonic flow regimes well. OpenFOAM experience puts you in a strong position here. If you have worked in a startup before, even better.

Ready to work on problems that push the limits of what simulation can do?
