Lead Electrical Engineer - Dot

About the Role

DoorDash Labs is a team within DoorDash building autonomous delivery robots and other autonomy solutions from the ground up for DoorDash's core delivery platform. If you have a passion for applying autonomy and robotics in a service used by millions of people daily, then we want to talk to you!

We are seeking an experienced and hands-on Senior Electrical Engineer to lead the design and development of the electrical systems for our 4-wheeled autonomous delivery robot. This role is responsible for delivering robust, production-ready hardware across high-speed digital design, PCBAs, RF integration, harnessing, and board-level packaging.

This is a deeply technical position for someone who can move seamlessly between system-level thinking and detailed circuit execution.

What You’ll Do

• Design and develop electrical systems for a complex mobile robotic platform from concept through production.
• Lead high-speed digital design efforts (PCIe, MIPI, Ethernet, DDR, multi-gigabit SERDES, etc.).
• Own PCBA development including schematic capture, stack-up definition, layout guidance, impedance control, and design-for-manufacture.
• Drive RF integration (Wi-Fi, LTE/5G, GNSS, Bluetooth, RADAR, and LiDAR), antenna placement, layout constraints, and signal integrity.
• Develop and review cable harness designs, connector selection, grounding strategy, and environmental robustness.
• Collaborate closely with mechanical engineering on board packaging, thermal management, vibration resistance, and environmental sealing.
• Define and implement power distribution architecture, battery interfaces, protection circuits, and system monitoring.
• Ensure compliance with EMI/EMC and regulatory requirements (FCC/CE) (CISPR-25 and FCC Part 15 Class A).
• Support prototype builds and bring-up, debug hardware/firmware interface issues, root-cause failures, and drive corrective actions quickly.
• Establish design standards and perform detailed design reviews across the EE team.
• Work cross-functionally with firmware, robotics, systems, manufacturing, and reliability teams.

What We’re Looking For

Required Qualifications

• B.S. or M.S. in Electrical Engineering (or equivalent experience).
• 7-10+ years of experience designing complex embedded hardware systems.
• Strong expertise in:
• High-speed digital circuit design and layout
• Multi-layer PCB design and stack-up planning
• Signal integrity and power integrity fundamentals
• RF integration and antenna considerations
• Cable harness and interconnect design

EMI/EMC mitigation

• Experience designing EMC/EMI input and output filters
• Experience taking hardware products from concept to production.
• Experience with mobile or ruggedized systems operating in real-world environments.
• Strong debugging and lab bring-up experience. 
• (VNA and Spectrum Analyzer experience is a plus)

Preferred Qualifications

• Experience in robotics, automotive, aerospace, or industrial automation.
• Familiarity with safety-critical or high-reliability systems.
• Experience with high-voltage battery systems.
• Experience with environmental, vibration, and regulatory testing.
• Background working with contract manufacturers and NPI processes.

Key Attributes

• Hands-on engineer who enjoys building and shipping real hardware.
• Strong systems intuition with at
