Senior Mixed-Signal / Analog Hardware Engineer

DoorDash USA•Oakland, CA

1d•$170,000 - $250,000•Hybrid

About The Position

DoorDash Labs is DoorDash's autonomous delivery group, building the robots and hardware that move goods without a driver. The Hardware team designs the electronics at the core of these systems — digital and mixed-signal control boards, power and motor-control electronics, embedded firmware, and the test and integration benches that prove the whole system works. We're building out an experienced and diverse set of electrical engineers to increase our velocity, bandwidth, and operations. You'll own mixed-signal and analog design — a key capability gap for the team — and raise the analog bar across our control hardware, from instrumentation and telemetry to sensor interfaces and precision analog. You will report into the Director, Electrical Engineering on our Hardware team in our DoorDash Labs organization. Our offices are open, and depending on the role this position is hybrid or fully onsite — expect to be fully onsite when needed.

Requirements

Strong mixed-signal and precision-analog design background
Instrumentation, telemetry, current-source, and power-amplifier design
ADC/DAC and signal-conditioning design; sensor front-ends (temp/light/audio) and LED drivers
EMC/EMI-aware design and mitigation experience
Characterize analog performance in the lab (noise, bandwidth, accuracy)

Responsibilities

Design instrumentation and telemetry-measurement circuits, precision current sources, and high-quality amplifiers
Design circuits around ADCs, DACs, and signal conditioning
Design sensor interfaces — temperature, light, audio — and LED drivers
Own power sequencing and EMC-aware analog design
Bring analog rigor to design reviews and help set analog/EMC design practices
