Founding Engineer

Builder’s instinct. Founder’s mentality. Serious engineering ability.

PRINCEPS (YC S26) is hiring Founding Engineers & we’re OFFERING $2.5K for all successful referrals!

The story of PRINCEPS (YC S26) is simple. Compute is now the most important commodity in the world. Trillions of dollars are pouring into chips, power and data centres. We're building the financial backbone of the compute economy, so capital can flow into the infrastructure that decides who wins the AI century.

We're a team of recent Oxford grads, structured finance and defence nerds, and one former competitive figure skater. We’re already working with compute operators, exchanges and capital partners across the US and Europe. Join us for great vibes, crazy ownership and the chance to build in a trillion-dollar market from day zero!
