Flight Software Engineering Intern (Simulation/Hardware-In-The-Loop) - Spring & Summer 2027

Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage. About the Team:   The Mission Systems Engineering Team develops and integrates the hardware and software that enable Hermeus aircraft to execute missions. As a Mission Systems Engineering Intern, you will work across avionics, software, communications, and system integration to help build, test, and troubleshoot mission capabilities. This role is ideal for someone with a strong mix of hands-on hardware experience and software development skills.   Spring: Around 16 weeks (January - April) Summer: Around 12 weeks (May - August) Responsibilities: • Support development of a 6-DOF flight simulation including vehicle dynamics, sensor/actuator models, and engine/plant models to verify flight software in closed loop. • Support hardware-in-the-loop (HITL) testing, including integrating flight computers, avionics, sensors, actuators, and cable harnesses. • Write simulation and test software primarily in C++, with Python and MATLAB used for modeling and tooling. • Troubleshoot and integrate hardware using schematics, pinouts, connectors, and common bench tools. • Build tooling that makes simulation and HITL testing fast, repeatable, and data-rich through logging, playback, and automation. • Independently own simulation and integration tasks from initial setup through testing and troubleshooting . Required Qualifications: • Currently pursuing a degree in Electrical Engineering, Computer Engineering, Computer Science, Software Engineering, Aerospace Engineering, or a related field. • Working proficiency in C++. • Strong understanding of physics and dynamics fundamentals, including rigid-body dynamics, classical mechanics, reference frames, and equations of motion. • Comfortable working hands-on with hardware, including reading schematics and pinouts, building or terminating cables, and troubleshooting hardware. • Comfortable using common bench tools such as a multimeter, oscilloscope, and power supply. • Comfortable working in a Linux command-line environment. • Demonstrated ability to work effectively on multidisciplinary technical teams. • GPA of 3.0 or above. Preferred Skills and Experience: • Working knowledge of MATLAB and/or Python for simulation modeling, analysis, and tooling. • Experience with 6-DOF simulation, flight or vehicle dynamics modeling, or software-in-the-loop (SITL). • Hardware-in-the-loop (HITL), real-time, or embedded systems experience. • GNC coursework or projects involving controls, state estimation, navigation, or flight dynamics. • Soldering, connectorization, or wire-harness fabrication experience. • Hands-on experience with robotics, UAVs/drones, rocketry, FSAE, CubeSat, or similar technical teams. • Previous simulation, GNC, avionics, or flight software internship experience. • Currently pursuing a graduate degree (MS or PhD) in Electrical Engineering, Computer Engineering, Computer Science, Software Engineering, Aerospace Engineering, or a related technical field.
