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)

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 .

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.

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.
