Job Description:

Guidance Navigation & Control Engineer (Experienced, Lead, Senior) Company: The Boeing Company Boeing Defense, Space & Security’s Experimental Systems Group (ESG) is hiring GN&C Engineers across Experienced, Lead, and Senior levels to rapidly prototype, develop, and field novel space and hypersonic capabilities. ESG delivers first-of-kind solutions for customers in a fast-paced, multidisciplinary environment, including the X-37B, the world’s first fully autonomous, reusable spaceplane. You will design GN&C algorithms, build high?fidelity simulations, implement and test flight software, and support integration and flight test in both atmospheric and space. Career growth opportunities are available for candidates with a passion for spacecraft or aircraft GN&C. environments. Key Responsibilities Design, implement, and verify guidance, navigation, and control algorithms for spacecraft, re-entry vehicles, and hypersonic/airborne platforms. 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.
