Senior GNC Engineer
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.
About the role
GNC is how our cargo aircraft knows where it is, decides where to go, and flies there with no pilot on board. As a Senior GNC Engineer you will own the GNC architecture. You will decide how the aircraft is controlled, how it estimates its state, how it behaves when sensors or actuators fail, and what evidence is needed before each new part of the envelope is flown. You will do a large share of the design work yourself and set the technical bar for the engineers around you.
Responsibilities
Own the GNC architecture, including control law structure, navigation solution, guidance modes, and redundancy management
Design flight control laws for all phases of flight, including takeoff, landing, and failure cases
