Avionics Engineer – Flight Electronics

El Segundo, California | On-site

This hands-on role owns the electronics across the interceptor, from board-level design and power systems to sensor integration, harnessing, and the electrical interface to the launcher. You will design boards, build and debug them yourself, and carry them through qualification and into flight.

You will work directly with the founders and with seeker, GNC, embedded software, propulsion, and mechanical engineers. The hardware you design will fly and intercept targets.

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.

• Define the avionics architecture across the flight computer, power distribution, and data buses
• Design, simulate, and lay out PCBs for computing, sensing, actuation, and power
• Own schematic capture, layout, component selection, DFM, and board vendor coordination
• Develop power systems including DC-DC conversion, batteries, protection circuitry, and transient management
• Integrate the seeker, IMUs, GNSS receivers, and electromechanical actuators
• Design signal conditioning and low-latency sensor and actuator interfaces for flight software and the autopilot
• Design wiring harnesses and the launcher electrical interface with the mechanical team
