Job Description

Guidance, Navigation, and Control (GNC) Engineer

Job Description

This role focuses on the design, development, and verification of advanced guidance, navigation, and control (GNC) systems for aerospace applications. The GNC Engineer develops autopilot and control algorithms, performs target state estimation and sensor fusion, and builds high-fidelity simulations to support system design and testing. The position supports both laboratory and field test activities and involves close collaboration with internal engineering teams and U.S. Department of Defense customers in secure environments.

Responsibilities

• Design, develop, and analyze guidance, navigation, and control algorithms for advanced aerospace systems.
• Develop autopilot and control laws for dynamic systems, including tuning and validation of control performance.
• Perform target state estimation, filtering, and sensor fusion to support accurate guidance and navigation solutions.
• Develop, maintain, and improve simulations and models, including state-space and 6-DOF models, to support system design and verification.
• Support hardware-in-the-loop (HIL), software-in-the-loop (SIL), and system-level testing to validate GNC performance.
• Assist with field testing and customer-supported test activities, including work with U.S. Department of Defense customers in secure environments.
• Collaborate closely with systems, software, and test engineering teams to integrate GNC algorithms into real-time embedded control systems.
• Contribute to flight dynamics modeling and sensor modeling to improve system accuracy and robustness.
• Interact with hardware in laboratory and office environments to support integration, troubleshooting, and performance evaluation.
• Help drive the development of in-house simulation capabilities and directly influence the technical direction of GNC solutions.

Essential Skills

• Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Aerospace Engineering, or a closely related field.
• 3+ years of experience in guidance, navigation, and control (GNC) engineering.
• Proficiency with MATLAB and Simulink for control system design, simulation, and analysis.
• Experience with Python and C++ for algorithm development and implementation.
• Strong knowledge in control system design, including state-space methods and PID control.
• Experience with 6-degree-of-freedom (6-DOF) simulation, control, and estimation.
• Experience with real-time embedded control systems and integrating GNC algorithms into embedded platforms.
• Experience with hardware-in-the-loop (HIL) and software-in-the-loop (SIL) testing.
• Experience with flight dynamics modeling and sensor modeling for aerospace applications.
• Familiarity with sensor fusion techniques and guidance optimization.
• Familiarity with missile, UAV, or aerospace vehicle systems.
• Experience supporting test activities with U.S. Department of Defense customers.
• Strong analytical, problem-solving, and debugging skills in a simulation and test environment.

Additional Skills & Qualifications

• Master’s degree in Mechanical Engineering, Electrical Engineering, Aerospace Engineering, or a related discipline is a plus.
• Experience with FPGA-based implementations or interaction with FPGA-controlled systems.
• Experience with advanced filters and state estimation techniques beyond basic implementations.
• Experience with control tuning and optimization for complex dynamic systems.
• Aerospace industry experience, particularly in small, fast-paced organizations.
• Ability to collaborate effectively with multidisciplinary engineering teams and communicate complex technical concepts clearly.

Work Environment

This position is based in Huntsville, Alabama, in an office building located in a research park environment. The work model is hybrid: you work on-site Monday through Wednesday for approximately nine hours per day, and you work from home on Thursday and for four hours on Friday. The office features dedicated office spaces rather than cubicles and includes access to hardware that you will interact with for testing and integration. You will work in both laboratory and office settings and may support field tests as needed. The culture emphasizes close collaboration with other engineering disciplines, direct ownership of in-house simulation development, and meaningful impact on the growth of the business. Work includes interaction with secure environments and coordination with U.S. Department of Defense customers.
