Senior Associate, Guidance Navigation and Control Engineer

L3Harris • Orlando, FL

1d • Onsite

About The Position

L3Harris Technologies is seeking an early-career Guidance, Navigation and Control (GNC) Engineer to join its Orlando, Florida team supporting missile programs and expanding all-up-round integration activities. The engineer will work alongside experienced engineers and apply foundational engineering principles to vehicle dynamics, aerodynamics, propulsion, classical and modern flight controls, tactical and strategic missile guidance, estimation theory, modeling and simulation, and system verification. The position offers opportunities to develop practical engineering skills through analysis, software development, integration, and evaluation of test data.

The role involves GNC design and analysis for tactical and strategic missile systems, including trajectory shaping and tuning guidance and autopilot parameters to meet customer requirements. The engineer will create and use aerospace vehicle models and simulations, implement algorithms in C/C++, develop high-fidelity component and subsystem simulations in MATLAB/Simulink, and analyze test telemetry for system verification and mission activities. The engineer will also investigate unexpected results and collaborate with multidisciplinary engineering teams to support vehicle integration and resolve interface issues. The employee must be able to obtain a U.S. security clearance.

The regular schedule is 9/80: work nine days in every 14-day period, totaling 80 hours, with every other Friday off. The position is located in Orlando, Florida.

Requirements

• Bachelor’s degree in Aerospace Engineering, Electrical Engineering, or another related technical field, and at least 2 years of related engineering experience; or a graduate degree or equivalent with 0–2 years of related experience; or, in lieu of a degree, at least 6 years of related experience.
• Ability to obtain a U.S. security clearance.

Nice To Haves

• Missile or launch-vehicle navigation and guidance experience or coursework.
• Ability to work in Windows and Linux environments.
• Experience with systems engineering disciplines and activities, such as requirements traceability and verification.
• Academic, research, internship, or professional experience applying vehicle dynamics, control theory, navigation, or estimation principles.
• Experience using MATLAB and Simulink for engineering analysis, modeling, or algorithm development.
• Programming experience in C, C++, Fortran, or Python.
• Coursework or project experience involving aerodynamics, propulsion, structural dynamics, or interactions between physical subsystems.
• Familiarity with systems engineering activities, including requirements development, traceability, and verification.
• Familiarity with version control and software development in Windows or Linux environments.

Responsibilities

• Perform GNC design and analysis for tactical and strategic missile systems.
• Conduct trajectory shaping and tune tactical and strategic missile guidance and autopilot parameters to meet customer requirements.
• Generate, modify, and use aerospace vehicle models and simulations based on first principles.
• Implement algorithms and modify simulations in a C/C++ coding environment while following Software Configuration Management (SCM) processes.
• Generate, modify, and use high-fidelity component and subsystem models and simulations in MATLAB/Simulink for tuning and requirements verification.
• Analyze real-time and post-test telemetry data in support of system-level verification and mission activities.
• Investigate unexpected results by examining underlying physics, modeling assumptions, software implementation, and data quality.
• Collaborate with aerodynamics, propulsion, electrical, mechanical, software, and test engineers to support vehicle integration and resolve interface issues.
