Electrical Engineer, Intern - Labs (Summer 2027)

DoorDash•Oakland, CA

8d•Onsite

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 designs 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 take the project from requirements through design, build, and bench validation, then present your results to the team at the end of the summer. You will report to the Director, Electrical Engineering in the DoorDash Labs organization. The internship is hosted during the summer, with a May or June 2027 start date, and requires working onsite at the Oakland, California office.

Requirements

Be pursuing a B.S. or M.S. degree in Electrical Engineering or an equivalent field.
Have no more than 2 years of full-time work experience.
Be graduating between Fall 2027 and Summer 2028.
Be available to start in May or June 2027.
Have 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.
Be able 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.
Understand lithium-ion battery charging, including CC/CV profiles and protection limits, and how a battery management system interfaces with a charger or load.
Have hands-on lab experience with oscilloscopes, differential probes, power supplies, and electronic loads, and be able to safely debug high-current, high-voltage hardware.
Be able to write Python or C/C++ for instrument automation, data acquisition, or microcontroller bring-up.
Be able 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, and incorporate design review feedback.
Document results and present findings to the team at the end of the internship.
