Guidance Navigation & Control Engineer (Associate or Experienced)

Guidance Navigation & Control Engineer (Associate or Experienced) Company: The Boeing Company Boeing Defense, Space & Security’s Experimental Systems Group (ESG) is hiring GN&C Engineers  across Associate, and Experienced 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 environments.  Career growth opportunities are available for candidates with a passion for spacecraft or aircraft GN&C.

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.

Bachelor of Science degree in Engineering, Engineering Technology (including Manufacturing Technology), Computer Science, Data Science, Mathematics, Physics, Chemistry or non-US equivalent qualifications directly related to the work statement    2+ years of engineering experience or a Masters Degree Engineering experience with aircraft, missile, spacecraft, autonomous platform or similar vehicles Experience using MATLAB and Simulink Experience developing GN&C algorithms, models and simulations.

Ability to work effectively in broad, minimally defined design spaces and to communicate technical results clearly 5+   years related technical experience or an equivalent combination of education and experience Active Tier 5 (T5) Clearance, formerly known as Single Scope Background Investigation (SSBI) is Preferred Experience with spacecraft operations, space environment effects, or hypersonic re ‑ entry GN&C Programming experience in C/C++ or comparable languages sufficient to implement and test GN&C algorithms Familiarity with state estimation and sensor fusion (e.g., Kalman filters), GPS/INS, or air data systems Background in classical and modern control theory and nonlinear control design Model ‑ based development experience and flight test support.
