Zachary Piper Solutions is seeking a Guidance, Navigation and Control (GNC) Engineer to support the development and prototyping of a hypersonic next generation fully autonomous reusable spaceplane in Seal Beach, CA . The GNC Engineer will Design, implement, and verify guidance, navigation, and control algorithms for spacecraft, re-entry vehicles, and hypersonic/airborne platforms. This position is onsite in Seal Beach, CA and requires an active TS/SCI Clearance. Responsibilities of the

GNC Engineer:

Develop and maintain 6 DOF dynamics simulations and associated analysis tools for mission and performance assessment. Implement and validate GN&C flight software (MATLAB/Simulink models and C/C++ prototypes) and integrate with testbeds and avionics. Apply astrodynamics and flight mechanics to mission design, novel orbit concepts, and trajectory optimization. Apply aerodynamics, atmospheric flight mechanics, and controls knowledge to support the design of re-entry guidance, navigation, and flight control functions. Develop powered and unpowered guidance laws and autonomy tools for on orbit and atmospheric operations. Support troubleshooting of operational anomalies, functional tests, and service incidents. Produce concepts of operations, simulation artifacts, and test procedures to enable rapid iteration from prototype to flight test. Collaborate with cross functional teams (systems engineering, avionics, test, and business development) and communicate technical tradeoffs to stakeholders. Independently identify inefficiencies, propose solutions, and implement reusable tools and automations. Qualifications for

GNC Engineer:
