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 an experienced Senior Account Executive to help drive Epsilon3's next phase of growth. This is a senior individual contributor role for someone who combines an engineering background with a proven track record of selling complex technical SaaS solutions.

You'll own the full sales cycle - from generating pipeline to closing business working directly with technical and executive stakeholders. Success in this role requires technical credibility, consultative selling skills, and a consistent history of exceeding revenue targets.
