About the Job

Requirements

  • Pursue a B.S. or M.S. degree in Electrical Engineering or equivalent, have no more than 2 years of full-time work experience, and be graduating between Fall 2027 and Summer 2028.
  • Be available to start in May or June 2027; internships are hosted only during the summer.
  • Have coursework or project experience in power electronics, including switch-mode converters (buck, boost, power factor correction, isolated DC-DC), gate drive, magnetics, and power-stage design.
  • Understand motor control fundamentals, including brushless DC/permanent magnet synchronous motor drives, inverter half-bridges, field-oriented control, and current and position sensing.
  • Understand analog and feedback-control fundamentals, including operational amplifier sensing circuits, analog-to-digital converter signal conditioning, loop compensation, and stability analysis.
  • Be able to capture schematics and lay out printed circuit boards using a tool such as Altium or KiCad, with awareness of high-current layout, thermal, and electromagnetic compatibility considerations.
  • Understand lithium-ion battery charging, including constant current/constant voltage profiles and protection limits, and how a battery management system interfaces with a charger or load.
  • Have hands-on laboratory 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 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.
  • Design, build, and bring up hardware, from schematic and component selection through prototype assembly and debug.
  • Characterize the design on the bench with laboratory equipment, measuring efficiency, thermal, 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.

About the Company

DoorDash

Runs apps for local food and grocery delivery

DoorDash runs apps that let people order restaurant meals, groceries, and other goods from local businesses, which independent couriers called Dashers bring to their doors. In 2019 it overtook Grubhub to become the largest food delivery service in the United States, and it later expanded abroad by buying Finland's Wolt and Britain's Deliveroo. Merchants pay DoorDash a fee on each order and can buy ads in its apps, while customers pay delivery and service fees or join DashPass, a subscription that cuts those fees. Businesses can also hire Dashers through its Drive service to carry orders placed on their own websites. Four Stanford students founded DoorDash in 2013, and it is based in San Francisco, California.
