Everything is actively being built, integrated, and tested on real hardware supporting real tests.\nThis role will focus on developing simulation and hardware-in-the-loop (HITL) infrastructure, combining software development, flight simulation, and hands-on hardware integration.\nSmall team, big ownership, and we move at speeds the rest of the industry doesn't.\nSpring-Summer: Around 28 weeks (January - August)\nResponsibilities:\nSupport development of a 6-DOF flight simulation including vehicle dynamics, sensor/actuator models, and engine/plant models to verify flight software in closed loop.\nSupport hardware-in-the-loop (HITL) testing, including integrating flight computers, avionics, sensors, actuators, and cable harnesses.\nWrite simulation and test software primarily in C++, with Python and MATLAB used for modeling and tooling.\nTroubleshoot and integrate hardware using schematics, pinouts, connectors, and common bench tools.\nBuild tooling that makes simulation and HITL testing fast, repeatable, and data-rich through logging, playback, and automation.\nIndependently own simulation and integration tasks from initial setup through testing and troubleshooting.\nRequired Qualifications:\nCurrently pursuing a degree in Electrical Engineering, Computer Engineering, Computer Science, Software Engineering, Aerospace Engineering, or a related field.\nWorking proficiency in C++.\nStrong understanding of physics and dynamics fundamentals, including rigid-body dynamics, classical mechanics, reference frames, and equations of motion.\nComfortable working hands-on with hardware, including reading schematics and pinouts, building or terminating cables, and troubleshooting hardware.\nComfortable using common bench tools such as a multimeter, oscilloscope, and power supply.\nComfortable working in a Linux command-line environment.\nDemonstrated ability to work effectively on multidisciplinary technical teams.\nGPA of 3.0 or above.\nPreferred Skills and Experience:\nWorking knowledge of MATLAB and/or Python for simulation modeling, analysis, and tooling.\nExperience with 6-DOF simulation, flight or vehicle dynamics modeling, or software-in-the-loop (SITL).\nHardware-in-the-loop (HITL), real-time, or embedded systems experience.\nGNC coursework or projects involving controls, state estimation, navigation, or flight dynamics.\nSoldering, connectorization, or wire-harness fabrication experience.\nHands-on experience with robotics, UAVs/drones, rocketry, FSAE, CubeSat, or similar technical teams.\nPrevious simulation, GNC, avionics, or flight software internship experience.\nCurrently pursuing a graduate degree (MS or PhD) in Electrical Engineering, Computer Engineering, Computer Science, Software Engineering, Aerospace Engineering, or a related technical field.","description_format":"text","description_chars":2917,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Design
