Epsilon3 is a multi-product operations management platform revolutionizing the way teams build, launch, and operate spacecraft and other advanced hardware systems.

Launched in 2021, our company is led by engineers from SpaceX, Google, and NASA, who have experience supporting over 100 space missions. Innovative teams at Blue Origin, Rocket Lab, Axiom Space, Firefly Aerospace, and many others depend on our web-based (SaaS) solutions to plan and track high-stakes procedures. We raised a $15M Series A funding round led by Lux Capital, Y Combinator (YC S21), and other world-class investors.

We’re looking for a Product Manager to own the strategy, roadmap, and execution for core areas of our platform, spanning procedure execution, manufacturing, test, telemetry & command, analytics, and AI-assisted workflows.

This is a high-ownership role within a fast-paced startup. The ideal candidate pairs strong product judgment with technical fluency, moves fast without breaking trust, and is energized by deep customer discovery alongside engineers, designers, and end users.
