About this role

Harbinger Motors is building electric vehicles for the commercial market, and this internship puts you directly into their battery testing operation during a formative growth phase. You'll work hands-on with high-voltage battery systems—designing test fixtures, developing test methods, collecting and analyzing data, and writing test plans across cell, module, and pack levels. The work is practical and technical, not administrative.

To succeed here, you need to be an engineering student (Electrical, Chemical, or Mechanical) with prior internship experience and genuine comfort with hardware: hand tools, basic wiring, low-voltage debugging, and ideally Python scripting. Experience with data acquisition equipment and automotive projects like Formula SAE or Baja SAE strengthens your candidacy, though neither is required. This role suits someone who wants to learn battery technology in a startup environment and doesn't mind being in the lab most days.

The internship runs either 8 weeks (January 11–March 12) or 15 weeks (January 11–April 30), full-time at the Garden Grove, CA facility. Pay is $25–35 per hour, and if you're relocating from more than 50 miles away, Harbinger provides a $1,000 stipend. You'll need work authorization or eligibility for a J-1/F-1 visa.
