Embedded Software Engineer (Firmware) - DoorDash Air

About the Team

DoorDash Labs, established in 2018, serves as the innovation hub for DoorDash, focusing on developing automation and robotics solutions to enhance last-mile logistics. The DoorDash Air team is bringing drone delivery to reality by designing high reliability, high power density converters, and fault-tolerant controls electronics.

About the Role

We are looking for an Embedded Software Engineer to lead the development and bring-up of ARM-based microcontroller platforms across our robotics products. This is a high-ownership role, directly responsible for building the low-level firmware that powers our platforms. You will design, implement, and validate firmware for motion control, sensor integration, communications, power management, and safety-critical functionality.

Responsibilities

• Own the firmware bring-up and integration for new embedded platforms (e.g. ARM Cortex-M series).
• Develop and maintain bare-metal firmware and RTOS-based applications for robotic subsystems (motor control, sensors, telemetry, power systems).
• Write and maintain robust, maintainable, and well-documented C/C++ code for embedded targets.
• Collaborate with the electrical engineering team on hardware bring-up, schematic review, and system integration.
• Lead system bringup, validation, and debug.
• Contribute to firmware safety, reliability, and system-level robustness.

Qualifications

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 4+ years of hands-on experience in embedded systems development.
• Deep expertise in bare-metal programming on ARM microcontrollers.
• Strong proficiency in C/C++ for embedded targets and firmware design patterns.
• Experience with hardware bring-up and low-level debugging on custom boards.
• Solid understanding of digital electronics, buses (I2C, SPI, UART, CAN), and embedded peripherals.
• Strong system-level thinking, with an ability to work independently and take ownership across the full development cycle.

Preferred Qualifications

• Experience with RTOS (e.g., FreeRTOS, Zephyr) or Embedded Linux on constrained systems.
• Familiarity with motor control, power systems, or battery management in robotics or automotive contexts.
• Experience working closely with hardware teams, reading schematics, and performing board-level debug.
• Familiarity with safety-critical systems, watchdogs, and fault handling.
• Comfortable working in fast-paced, high-ownership engineering environments like those found in startups or advanced R&D teams.
