Cowboyspace The Senior Mechanical Engineer at Cowboy Space Corporation designs and builds physical spacecraft systems from concept through flight. This hands-on role involves working across structures, mechanisms, thermal systems, and packaging to deliver flight-ready hardware.

Responsibilities

As a Senior Mechanical Engineer, you will play a key role in designing and building the physical systems that enable our spacecraft to operate reliably in space. You will own critical hardware from concept through flight, working across structures, mechanisms, thermal systems, and packaging to deliver high-performance, flight-ready designs.
This is a hands-on role at the center of hardware development. You will work closely with propulsion, power, avionics, GNC, and software teams to design integrated systems, rapidly prototype, and validate through testing. You’ll be expected to move quickly, iterate often, and take ownership of hardware that directly impacts mission success.
