Job Description:

Guidance Navigatoin & Control Engineer 4

Location: Seal Beach, California (Onsite)

Candidates must be able to obtain and/or maintain a Department of Defense Top Secret clearance as a condition and continuation of employment.

Role Overview

This is a non-managerial, non-leadership role focused on rapidly prototyping, developing, and fielding novel space and hypersonic capabilities. The position involves delivering first-of-kind solutions in a fast-paced, multidisciplinary environment. You will design guidance, navigation, and control (GN&C) algorithms, build high-fidelity simulations, implement and test flight software, and support integration and flight tests in both atmospheric and space 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 and communicate technical tradeoffs to stakeholders.
• Independently identify inefficiencies, propose solutions, and implement reusable tools and automations.

Required Qualifications

Education: A Bachelor of Science degree in Engineering, Engineering Technology, Computer Science, Data Science, Mathematics, Physics, Chemistry, or an equivalent qualification is required.

Experience: 5+ years of related work experience. A PhD, or a Master's degree with 3 or more years of related work experience, is also acceptable. Engineering experience with aircraft, missile, spacecraft, autonomous platforms, or similar vehicles is necessary.

Technical Skills: Proficiency with MATLAB and Simulink is required, along with proficiency in developing GN&C algorithms, models, and simulations. Experience developing with C/C++, Python, or C# is also required.

Preferred Qualifications

• Degree in aerospace/aeronautical engineering (BS/MS/PhD).
• 10+ years of related technical experience or an equivalent combination of education and experience.
• 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.
