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 are looking for a Senior Product Designer to lead the end-to-end design of mission-critical interfaces. You will work at the intersection of human-computer interaction and aerospace engineering, solving complex problems related to real-time telemetry, AI-assisted decision making, and high-stakes procedure management.
 
As a senior member of the team, you will be helping map the entire service ecosystem— translating research and feedback to service blueprints and into high-fidelity, testable prototypes.
