Job description

Guidance Navigation & Control Engineers (Senior or Principal) Company: The Boeing Company Boeing Defense, Space & Security’s Experimental Systems Group (ESG) is hiring Guidance Navigation & Control Engineers (Senior or Principal) to join our team in Seal Beach or El Segundo, CA. These positions are to help rapidly prototype, develop, and field novel space 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 space environments. You will develop advanced technical capabilities and lead engineering project teams.

Position Responsibilities

• Design, implement, and verify guidance, navigation, and control algorithms for spacecraft
• 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
• Develop powered and unpowered guidance laws and autonomy tools for on‑orbit 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
• Lead engineering project teams, mentor engineers and advance job practices and techniques as it relates to GN&C

Basic Qualifications (Required Skills/Experience)

• 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
• Active Tier 5 (T5) Clearance, formerly known as Single Scope Background Investigation (SSBI) is required
• Level 5: 14+ years of related work experience or an equivalent combination of education and experience
• Engineering experience with spacecraft
• Experience using MATLAB and Simulink
• Experience developing GN&C algorithms, models and simulations

Preferred Qualifications (Desired Skills/Experience)

• Level 6: 20+ years of related work experience or an equivalent combination of education and experience
• Ability to work effectively in broad, minimally defined design spaces and to communicate technical results clearly
• Experience with spacecraft operations, space environment effects
• 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
• Background in classical and modern control theory and nonlinear control design
• Model‑based development experience and flight test support.
• Leadership skills to lead and influence positive outcomes
• Previous experience leading, mentoring, and engaging individuals and teams
• Experience providing active mentorship and career guidance
