## 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)
