Senior GNC Engineer - Air Platform / Missile Systems with Security Clearance

Senior Guidance, Navigation, and Control (GNC) Engineer - Air Platform / Missile Systems TSC is seeking a highly skilled Senior Guidance, Navigation, and Control (GNC) Engineer to lead the development of precision flight control, guidance, and navigation algorithms for next-generation missile and advanced air-platform systems. This position plays a critical role in shaping system-level performance, informing requirements, and guiding technical strategy across the full development lifecycle.

The ideal candidate has deep expertise designing and analyzing GNC architectures, developing high-fidelity 6-DOF simulations, integrating advanced navigation solutions, and validating algorithms through Hardware-in-the-Loop (HWIL) and flight testing. This onsite role at the Naval Research Laboratory (Washington, DC) requires daily collaboration with government scientists, program managers, and multidisciplinary engineering teams.

Responsibilities:

• Lead the design, development, and tuning of guidance laws, flight control algorithms, and navigation filters
• Develop and maintain high-fidelity 6-DOF time-domain simulations to characterize system performance, evaluate mission effectiveness, and drive requirements allocation.
• Integrate GPS/INS navigation solutions and seeker-based measurements, including sensor fusion and denied-environment navigation techniques.
• Inform system and mission-level requirements, supporting Systems Engineering in defining Technical Performance Metrics, and stability/control criteria.
• Conduct Hardware-in-the-Loop (HWIL) testing, bench testing, and flight-test algorithm validation; analyze test telemetry and generate performance assessments.
• Mentor junior GNC engineers and provide technical leadership across modeling, simulation, implementation, and verification activities.

Requirements:

• US Citizenship with an active DoD Secret clearance and the ability to obtain and maintain a TS/SCI clearance
• Master's degree or Ph. D. in Aerospace, Mechanical, Electrical, or related Engineering field
• Minimum 8 years of direct experience developing GNC algorithms for missiles, air platforms, or other advanced aerospace systems
• Expert proficiency in MATLAB/Simulink, C++, and model-based design workflows
• Hands-on experience developing 6-DOF simulations, HWIL environments, and flight-test validated GNC algorithms
• Experience in integrating and evaluating INS/GPS navigation, seekers, and multisensor fusion techniques
• Strong communication and collaboration skills with the ability to interface effectively with technical teams, and senior decision-makers

Preferred Requirements:

• Background in hypersonic vehicle GNC, high-speed aerodynamics, or aerothermal-affected flight control
• Familiarity with configuration management tools, version control workflows, and multidisciplinary engineering environments

In compliance with applicable pay transparency laws, the expected salary range for this position is $130,000 - $185,000 per year, depending on experience and location.
