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. Working alongside experienced engineers, the position applies 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 role offers opportunities to develop practical engineering skills through analysis, software development, integration, and evaluation of test data.

Requirements

• Bachelor’s degree in Aerospace Engineering, Electrical Engineering, or another related technical field, and at least 2 years of prior related engineering experience; alternatively, a graduate degree or equivalent with 0 to 2 years of prior related experience; or, in lieu of a degree, at least 6 years of prior 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 related 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 first-principles models and simulations of aerospace vehicles.
• Implement algorithms and modify simulations in C/C++ 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 engineers across aerodynamics, propulsion, electrical, mechanical, software, and test disciplines to support vehicle integration and resolve interface issues.
