Guidance Navigation & Control Engineer (entry - level, Associate, Experienced)

GN&C Engineer

At Boeing, we innovate and collaborate to make the world a better place. We're committed to fostering an environment for every teammate that's welcoming, respectful and inclusive, with great opportunity for professional growth. Find your future with us.

Boeing Defense, Space & Security's Experimental Systems Group (ESG) is hiring GN&C Engineers across Entry, 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.

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.

Basic Qualifications

• Bachelor of Science degree from an accredited course of study in engineering, engineering technology (includes manufacturing engineering technology), chemistry, physics, mathematics, data science, or computer science
• Strong fundamentals in astrodynamics and/or aerodynamics and linear algebra
• Experience using MATLAB and Simulink
• Programming experience in C/C++ or comparable languages sufficient to implement and test GN&C algorithms
• Ability to work effectively in broad, minimally defined design spaces and to communicate technical results clearly.

Preferred Qualifications

• Degree in aerospace/aeronautical engineering (BS/MS/PhD).
• 1+ years related technical experience or an equivalent combination of education and experience.
• 3+ 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.
• Experience developing simulations and mathematical models for GN&C or related problems
• 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.
• Prior work on space or hypersonic programs.
