Electromagnetics Engineering Intern (Spring)

The role

You will work alongside the design engineering team on real hardware programs. You will contribute to electromagnetic design, analysis, and tooling for characterization and optimization workflows.

What you will do

• Build and run finite element models to predict motor performance
• Perform electrical machine sizing and preliminary design trades
• Develop and maintain Python-based analysis and post-processing tooling
• Support multi-physics optimization studies
• Correlate simulation results against dynamometer and instrumentation data
• Document methods and results

Required qualifications

• 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
• 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

Nice to have

• JMAG strongly preferred
• Familiarity with permanent magnet synchronous machines and traction-class motor design
• Hands-on lab or test experience (dynamometer testing, power measurement, instrumentation)
• Understanding of power electronics and three-phase systems
• Familiarity with CAD tools (Solidworks preferred)
• Familiarity with drawing creation & tolerancing

Benefits

• Flexible hours (deliverable-based goals)
• Relocation package
• Monthly company events
• Friday Team Lunches
