About Poseidon Aerospace:
Poseidon Aerospace is reimagining how the world moves goods. We build and operate full-size autonomous cargo aircraft - capable of carrying two tons of payload over a thousand nautical miles. From remote communities to contested logistics operations, our platforms unlock a new cost curve for air freight, making it faster, cheaper, and accessible anywhere it's needed. Headquartered in the San Francisco Bay Area with locations in Washington DC, Oregon, and Maine; we're building something consequential.
As an Avionics Engineer at Poseidon Aerospace, you will contribute to the design, integration, and validation of the avionics systems powering our aircraft. You will help develop an efficient and reliable system that support propulsion, control, and autonomy across our fleet.
Responsibilities
- Own the integration of flight computers, sensors, actuators, and communication suites into a cohesive aircraft system.
- Develop comprehensive wiring diagrams, interconnect drawings (ICDs), and system schematics.
- Configure and troubleshoot data bus architectures (e.g., CAN, ARINC 429, RS-232/485, and Ethernet).
- Support electrical load analysis (ELA) and ensure clean power distribution and EMI/EMC mitigation across the airframe.
- Assist in the "bench-to-bird" process, including building test harnesses, breadboarding circuits, and performing HIL (Hardware-in-the-Loop) testing.
- Act as the technical glue between the software team, the mechanical structures team, and the flight test pilots.
- Get hands-on with the aircraft to diagnose "gremlins" during ground and flight testing, using everything from oscilloscopes to data logs.
Qualifications
- A background in integrating complex electronic systems on vehicles (aircraft, UAVs, or high-performance automotive).
