Senior GNC Engineer

The role

You will shape the in-orbit performance of a novel space vehicle. Your work spans vehicle-level dynamics and control, orbit propagation, flight software and HITL testing on avionics.

What you will do

• Come up with creative solutions to unique problems for putting reflected sunlight on the ground from space.
• Design, develop and test closed-loop guidance, navigation and control for attitude and orbit.
• Plan trajectories and attitude motion profiles that satisfy spot serving constraints.
• Develop and own 6-DOF simulation of vehicle attitude and orbital dynamics.
• Use 6-DOF simulation to characterize vehicle performance through Monte Carlo analysis.
• Write GNC algorithms in flight software (C++/Rust) and validate them using avionics in the loop.
• Drive sensor and actuator selection with avionics engineers.
• Analyze and plan orbits and constellation design to maximize spot serving capability.

Required qualifications

• 5+ years of professional GNC engineering experience.
• Clear technical ownership of a GNC subsystem that has flown, covering simulation, algorithms and flight software.
• Strong background in modeling physical systems from first principles, including flexible body dynamics, sensors, actuators and the space environment.
• Expertise in state estimation design for attitude and orbit determination, validated in flight.
• Ability to verify and validate GNC flight software in an integrated environment, using HITL testing.
• Experience in guidance, maneuver and constellation design, including orbit selection, coverage and station-keeping.
• Experience in real-time spacecraft operations support, from commissioning through console operations to on-orbit anomaly resolution.
• Fluency in Python, C++ and/or Rust.

Nice to have

• Ideally on spacecraft or other dynamically controlled vehicles.

Benefits

• Broad choice of medical/dental/vision coverage, Reflect covers 100% of each base-policy
• Access to HSA, FSA, and 401K
• Unlimited paid time off
• Healthy lunches provided daily
