Design, plan, and execute spacecraft and subsystem test campaigns, including vibration, thermal, thermal vacuum, EMI/EMC, functional, and automated testing. Develop test procedures, fixtures, instrumentation, and ground support equipment; analyze test data; document results and non-conformances; and collaborate with engineering, manufacturing, and software teams. Support satellite commissioning and operations, process improvements, requirements verification, and occasional off-hours or weekend testing.
Wanna join the adventure?
As a Test Engineer at Loft Orbital, you’ll design, plan, and run the test campaigns that prove our space hardware is ready for the real thing. You’ll get your hands on everything from individual subsystems to fully integrated spacecraft, putting them through environmental, functional, and automated testing. And when our satellites launch, your work doesn’t stop at the cleanroom door: you’ll periodically join our on-orbit team to help commission and operate live missions.
You’ll be at the center of the action, working side by side with design, manufacturing, and software teams to build test plans, execute environmental and functional procedures and scripts, and dig into the data to confirm every satellite and component meets its mission requirements. Along the way, you’ll build expertise across a wide range of complex aerospace hardware and software, on a fast-moving team that values collaboration and technical excellence.
