GNC Engineer, Senior - Orlando, FL

About Lockheed Martin

Lockheed Martin is a global security and aerospace company employing approximately 114,000 people worldwide, engaged in the research, design, development, manufacture, integration, and sustainment of advanced technology systems, products, and services. Lockheed Martin Missiles and Fire Control (MFC) is one of four Lockheed Martin business areas.

A Guidance and Control (GNC) Engineer will design, analyze, integrate, test, and validate algorithms and hardware that enable a vehicle—whether a missile, unmanned aircraft, or manned spacecraft—to determine its position, trajectory, and how to get there safely and accurately. The role bridges multidisciplinary domains, combining control theory, aerospace dynamics, hardware modeling, simulation, and system-level architecture.

• Develop guidance law algorithms and verify performance with high-fidelity simulation and data analysis.
• Create trajectory-generation tools that produce feasible, optimal paths while accommodating all vehicle hardware and dynamic limitations.
• Design closed-loop control laws to enable vehicle state manipulation that achieves the commanded mission; generate high-fidelity simulations to verify performance.
• Evaluate system performance in complex scenarios and environments and verify system and subsystem level requirements.
• Conduct Monte‑Carlo and sensitivity analyses to quantify the impact of sensor errors, actuator degradations, and flight‑environment variations on system performance.
• Perform critical studies, analyses, and test activities that support ground and flight test efforts including Hardware-In-The-Loop (HWIL) activities.
• Provide technical team leadership required to achieve specific work package objectives.
• Provide technical guidance, code reviews, and training for less‑experienced engineers.
• Support program reviews and technical interchange meetings with internal leadership and/or external customers.

• BS in electrical engineering, mechanical engineering, aerospace engineering, physics, computer science, applied mathematics, or similar STEM degree.
• 8+ years of hands‑on experience performing guidance, navigation, or flight control engineering on aerospace or missile applications.
• US Citizenship and an ability to attain Secret Clearance is required. An Interim Clearance is needed to start this position.
• Demonstrated responsibility for the full life‑cycle of GNC algorithms (concept, requirements generation, design, implementation, verification, and flight test).
• Demonstrated expertise in relevant mathematical concepts like linear algebra, dynamics, coordinate frame transformations, and fundamental control theory (PI filters, Laplace transform, Fourier analysis, state-space modeling, etc.).
• Demonstrated expertise in guidance law or autopilot/flight controls algorithm development, test, and verification.
• Demonstrated experience with SW development environments like Git using programming languages such as MATLAB, Python, C++, FORTRAN, or Ada.
• Demonstrated ability to lead technical teams to achieve specific work package objectives.
• Excellent written communication skills to include generation and presentation of verification plans, analysis reports, algorithm description documentation, and other technical documents.
• Effective oral presentation skills for design reviews and briefings to customers, partners, and senior leadership.

• Master's degree in an engineering discipline with concentration in controls, flight dynamics, or guidance.
• Experience using a Linux-based operating system.
• Experience integrating and testing hardware and software in Hardware In-the-Loop (HWIL).
• Experience with flight-control hardware, actuator interfaces, and inertial sensors.
• Use of oscilloscopes, logic analyzers, spectrum analyzers, and high-speed data acquisition for timing and EMI verification.
• Execution of HIL/SIL campaigns and support of ground-test and flight-test campaigns.

This position requires a government security clearance; you must be a U.S. Citizen for consideration. Clearance Level: Secret with Investigation or CV date within 5 years.
