Spacecraft Test Engineer (All Levels)

Xona Space Systems•Burlingame, CA

About The Position

Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth. With Pulsar – the world’s most advanced PNT satellite infrastructure in Low Earth Orbit – Xona will offer a future-proof, backwards-compatible global positioning system optimized for absolute precision, superior power, and robust protection. This is a hands-on test and integration role supporting first-article spacecraft builds and environmental testing. You will help plan and execute thermal vacuum (TVAC), vibration, and functional tests, work closely with mechanical, thermal, electrical, and systems engineers, and help drive spacecraft toward flight readiness. Ideal candidates are organized, responsible, and comfortable working directly with hardware. Strong mechanical design experience is not required; what matters most is operational mindset, attention to detail, and test execution ownership. We are open to multiple experience levels junior engineers will grow rapidly in test execution and spacecraft integration; senior engineers can take ownership of campaigns, vendors, and processes.

Requirements

BS or MS in Mechanical, Aerospace, Systems, Test, or relevant engineering field
Experience with hardware testing (lab, environmental, aerospace, or similar)
Interest in spacecraft integration, testing, and hands-on hardware
Strong attention to detail, organization, and documentation
For U.S. Roles: To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the United States (i.e. Green Card holder), or other protected individual as defined by 8 U.S.C. 1324b(a)(3).
For U.K. Roles: To comply with U.K. regulations, this role requires Baseline Personnel Security Standard (BPSS) checks, and successful candidates must be eligible to obtain UK Security Clearance (SC).
For Canada Roles: Successful candidates must obtain and hold a security clearance at the reliability status level, and pass security assessment for the Canadian Controlled Goods Program (CGP) and ITAR.
