## Description

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:  **

You'll join a small, fast-moving team building the avionics and flight software for a new flight vehicle program from clean sheet. Everything is actively being built, integrated, and tested on real hardware supporting real tests.

This role will focus on developing simulation and hardware-in-the-loop (HITL) infrastructure, combining software development, flight simulation, and hands-on hardware integration.

Small team, big ownership, and we move at speeds the rest of the industry doesn't. 

 

Spring-Summer: Around 28 weeks (January - 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.
