Early Career1

Operations is the largest group (9 of 23 roles, ahead of Engineering's 7), so hiring is weighted toward flying, testing, deploying and supporting aircraft rather than design alone; all roles are in El Segundo and none are remote.

Who they need

Seniority: Mostly mid-level (10) and senior (8), with 1 manager, 1 junior and 2 unlisted.

Skills named most: avionics, solar-powered aircraft, flight hardware, GNC, RF, Linux command line, telemetry, power systems, first-principles sizing, work instructions, corrective actions, ground control station software

Locations: All 23 roles are listed in El Segundo. None are listed as remote.

How to use this

If you're applying: Most openings are Operations and Engineering roles in El Segundo, and none are remote. The flight operations roles ask for Linux command line experience, and the Flight Operations Crew Chief role also asks for FAA Part 107 certification. Engineers earlier in their careers can look at the Engineer (Formula SAE Track) role.

If you're selling or recruiting: Operations has 9 open roles and Engineering has 7, all in El Segundo. Three roles opened in the last 30 days and one closed. Relevant angles are flight operations and avionics hiring, plus defense business development and network accreditation work (Strategic Growth Manager, Network Engineer). The company's site describes stratospheric sensing and secure direct-to-device comms.
