About the role
- ABOUT POSEIDON AEROSPACE: Poseidon Aerospace is reimagining how the world moves goods.
- 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.
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.
- 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.
- We build and operate full-size autonomous cargo aircraft; Heron, a seaplane, and Egret, a STOL aircraft; each capable of carrying two tons of payload over a thousand nautical miles.
- 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.
- Relocation support if applicable
Requirements
- Proficiency in schematic capture/harness design tools (e.g., Altium, AutoCAD Electrical, Capital) and a solid grasp of basic circuit theory.
- Ability to understand how a change in a sensor's sample rate might impact the flight controller or the pilot's display.
- A background in integrating complex electronic systems on vehicles (aircraft, UAVs, or high-performance automotive).
- Comfortable using lab equipment (multimeters, oscilloscopes, logic analyzers) to debug hardware and signal issues.
- Strong communication skills to explain technical trade-offs to non-electrical teammates.
Nice to have
- Familiarity with DO-160, DO-178, or DO-254 standards.
- Experience with antennas, GPS, or telemetry link integration.
- Proficiency in Python or C/C++ for automating tests or parsing flight data.
- Experience spinning quick-turn boards for break-out boxes or signal conditioning.
- A private pilot license or Part 107 (UAV) certification is a huge plus
