Avionics Technician – Flight Electronics Build

El Segundo, California | On-site

In this role you will build, assemble, and test the flight electronics for two interceptor product lines. You will fabricate wiring harnesses, assemble and rework circuit boards, and help integrate avionics into the vehicle and test setups. You will report to the avionics lead.

You will also work alongside mechanical, propulsion, GNC, and seeker engineers, and the hardware you build will go straight into test and demonstration campaigns.

We are a seed‑stage, venture‑backed defense technology company building affordable, modular interceptors for air and missile defense, with surface‑launched and space‑based platforms in development. The team has already demonstrated autonomous intercepts and is moving quickly from prototype hardware into flight testing from our South Bay facility. We are a small group of engineers and operators who design, build, and test in-house, with a clear path toward scaled production for government customers.
