About the role
Our team at H3X is hiring an intern to work alongside our design engineering team on real hardware programs. This is a hands-on role: you will contribute directly to electromagnetic design, analysis, and the tooling that supports our characterization and optimization workflows. You will see your work flow from simulation through to physical test data. We are looking for a full time Spring Intern, but also have availability for Summer 2027 and extended Co-Op positions.
What they're looking for
- Currently pursuing a BS, MS, or PhD in Electrical Engineering, Mechanical Engineering, or a related field
- Coursework or project experience in electric machines and electromagnetics
- Experience with FEA for electromagnetic analysis (JMAG strongly preferred, Ansys Maxwell, MotorCAD, or similar is acceptable)
- Working knowledge of electrical machine sizing fundamentals, magnetic and electric loading, winding design, and the relationships between geometry and performance
- Proficiency in Python for data analysis and automation
- Exposure to multi-physics or design optimization methods (parametric sweeps, Pareto trade studies, coupled EM-thermal-structural analysis, multi-variable optimization algorithms)
More about this role
H3X is building America's advanced electric motor company, powering next-generation platforms in aerospace, defense, and marine. Our integrated motor drives deliver 12+ kW/kg, roughly 3x the power density of competing solutions. We're now scaling to megawatt-class systems, with customers working on everything from supersonic aircraft to turbine power generation for AI datacenters.
Our team brings together engineers and operators from aerospace, defense, and motorsports, with deep expertise in electric machines, power electronics, material science, and advanced manufacturing. We're a small, fast-moving team doing hard engineering that matters, and we're looking for people who want to do the best work of their careers alongside us.
