Test Engineer

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.

About this role

• Support the design, development, and execution of test procedures, setups, and instrumentation for spacecraft and subsystem-level testing.
• Participate in the development and implementation of automated and manual test equipment, fixtures, and/or ground support equipment (GSE).
• Execute and document environmental and functional tests, including vibration, thermal, thermal vacuum (TVAC), and EMI/EMC.
• Collect, analyze, and interpret test data; generate reports and document results, flags, and non-conformances.
• Collaborate cross-functionally to ensure tests align with mission requirements, schedules, and quality standards.
• Contribute to process improvement initiatives for test documentation, configuration control, and data management.
