Job Description 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 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 space plane. 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. Basic Qualifications
* 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

* 5+ years of related work experience OR an equivalent combination of education and experience (Ex. PhD, Master's + 3 or more years' related work experience)

* Engineering experience with aircraft, missile, spacecraft, autonomous platform or similar vehicles

* Proficiency with MATLAB and Simulink

* Proficiency developing GN&C algorithms, models and simulations

* Experience developing with C/C++, Python or C#.

Preferred Qualifications
* Degree in aerospace/aeronautical engineering (BS/MS/PhD)

* 10+ 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

* 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

* Ability to work effectively in broad, minimally defined design spaces and to communicate technical results clearly. Relocation:
