Electrical Engineer, Intern - Labs (Summer 2027)

The role

You will own a defined hardware project involving an on-board charger prototype, an in-house motor control circuit, or a full-power hardware test bench. You will design, build, and validate hardware from requirements through prototype assembly and debug.

What you will do

• Own an end-to-end project in one of three areas: an on-board charger prototype, an in-house motor control circuit, or a full-power hardware test bench.
• Design, build, and bring up hardware, from schematic and component selection through prototype assembly and debug.
• Characterize design on the bench with lab equipment, measuring efficiency, thermal, and control performance against requirements.
• Collaborate with power electronics, firmware, and test engineers.
• Incorporate design review feedback into work.
• Document results and present findings to the team at the end of the internship.

Required qualifications

• Pursuing a B.S. or M.S. Degree in Electrical Engineering or equivalent
• No more than 2 years of full-time work experience
• Graduating between Fall 2027 to Summer 2028
• Available for a May or June 2027 start date
• Coursework or project experience in power electronics, including switch-mode converters (buck, boost, PFC, isolated DC-DC), gate drive, magnetics, and power-stage design
• Understand motor control fundamentals, including BLDC/PMSM drives, inverter half-bridges, field-oriented control, and current and position sensing
• Understand analog and feedback-control fundamentals, including op-amp sensing circuits, ADC signal conditioning, loop compensation, and stability analysis
• Can capture schematics and lay out PCBs in a tool such as Altium or KiCad, with awareness of high-current layout, thermal, and EMC considerations
• Understand lithium-ion battery charging (CC/CV profiles, protection limits) and how a battery management system interfaces with a charger or load
• Hands-on lab experience with oscilloscopes, differential probes, power supplies, and electronic loads
• Can safely debug high-current, high-voltage hardware
• Can write Python or C/C++ for instrument automation, data acquisition, or microcontroller bring-up
