Electrical Engineer, Intern - Labs (Summer 2027)
About The Position
DoorDash Labs is DoorDash’s autonomous delivery group, building robots and hardware that move goods without a driver. The Vehicle Electrical team develops electronics for these systems, including power and motor-control electronics, charging, and test benches. As a summer intern, you will own a defined hardware project in one of three areas: an on-board charger prototype, an in-house motor control circuit, or a full-power hardware test bench with motor power and battery simulation. You will carry the project from requirements through design, build, and bench validation, then present your results to the team at the end of the summer. The role reports to the Director, Electrical Engineering in DoorDash Labs and is based onsite at the Oakland, California office.
Requirements
- Pursuing a B.S. or M.S. degree in Electrical Engineering or equivalent.
- No more than two years of full-time work experience and graduating between Fall 2027 and Summer 2028.
- Available to start in May or June 2027; internships are hosted only during the summer.
- Coursework or project experience in power electronics, including switch-mode converters (buck, boost, PFC, isolated DC-DC), gate drive, magnetics, and power-stage design.
- Understanding of motor-control fundamentals, including BLDC/PMSM drives, inverter half-bridges, field-oriented control, and current and position sensing.
- Understanding of analog and feedback-control fundamentals, including op-amp sensing circuits, ADC signal conditioning, loop compensation, and stability analysis.
- Ability to capture schematics and lay out PCBs using a tool such as Altium or KiCad, with awareness of high-current layout, thermal, and EMC considerations.
- Understanding of lithium-ion battery charging (CC/CV profiles and 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, with the ability to safely debug high-current, high-voltage hardware.
- Ability to write Python or C/C++ for instrument automation, data acquisition, or microcontroller bring-up.
- Ability to work onsite at the Oakland, California office.
Responsibilities
- Own an end-to-end project involving 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 debugging.
- Characterize designs on the bench using lab equipment, measuring efficiency, thermal performance, and control performance against requirements.
- Collaborate with power electronics, firmware, and test engineers, incorporating design-review feedback.
- Document results and present findings to the team at the end of the internship.
Benefits
