Job summary

Humble Robotics is seeking an Embedded Engineer to craft safety‑critical, real‑time firmware for automotive ECUs. You’ll drive the full firmware lifecycle from bring‑up to production deployment and work closely with hardware, systems, and safety teams.

The role involves developing bootloaders, drivers, and middleware, implementing CAN, LIN, and Automotive Ethernet, and validating with unit and hardware‑in‑loop tests. You’ll contribute to a high‑velocity AV program in the SF Bay Area.

Qualifications

• BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or related field.
• 3+ years of production embedded firmware in C/C++.
• Experience with 32‑bit ARM Cortex‑M or automotive‑grade MCUs.
• Experience developing custom HAL, drivers, and middleware on bare‑metal or lightweight RTOS.
• Working knowledge of safety‑rated Real‑Time Operating Systems.
• Experience with CAN, LIN and interfaces SPI, I2C, UART.
• Proficient with Git and a Linux development environment.
• Eligible to work in the United States.

Responsibilities

• Architect, develop, debug, and test real‑time embedded firmware in C++ for automotive-grade MCUs.
• Develop and maintain bootloaders, low‑level drivers, middleware, and RTOS configurations.
• Implement automotive communication protocols (CAN, LIN) and interfaces (SPI, I2C, UART).
• Collaborate with hardware engineers on schematic review, bring‑up, and co‑debugging.
• Manage reliable communications between compute and embedded platforms in the vehicle.
• Partner with Tier 1s to integrate vehicle components.
• Develop and execute unit, integration, and hardware‑in‑loop test strategies.
• Root‑cause board‑level and vehicle‑level issues in the field.
• Support manufacturing test development and vehicle software deployment.

About Humble Robotics

Working at Humble Robotics means taking on the biggest change in ground transportation in decades. We’re building an autonomous, zero-emissions hauler that dramatically lowers the cost of freight with groundbreaking vision-based AI, designed for today’s global logistics network.

We’re a fast-moving, close-knit team of AV industry veterans and innovative thinkers. We don’t believe culture can be engineered – but when it falls into place, it’s a once-in-a-lifetime adventure.

Progress has never felt so present.

Position Overview

As an Embedded Engineer, you will develop safety-critical, real-time firmware for automotive ECUs powering vehicle control and supervisory functions. You will work across the full firmware lifecycle, from board bring-up to production deployment, collaborating closely with hardware, software, systems, and safety engineering teams.

Key Responsibilities

• Architect, develop, debug, and test real-time embedded firmware in C++ for automotive-grade microcontrollers
• Develop and maintain bootloaders, low-level drivers, middleware, and RTOS configurations
• Implement and integrate automotive communication protocols (CAN, LIN, Automotive Ethernet) and peripheral interfaces (SPI, I2C, UART)
• Collaborate with hardware engineers on schematic review, board bring-up, and hardware-software co-debugging
• Manage reliable communications between compute and embedded platforms on the vehicle
• Partner with Tier 1s to integrate vehicle components
• Develop and execute unit, integration, and hardware-in-loop test strategies
• Root-cause both board-level and vehicle-level issues in the field
• Support manufacturing test development and vehicle software deployment.

Minimum Qualifications

• BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or related field
• 3+ years developing production embedded firmware in C/C++
• Experience with 32-bit ARM Cortex-M or similar automotive-grade microcontrollers
• Experience developing custom HAL, drivers, and middleware on bare-metal or lightweight RTOS platforms
• Working knowledge of safety-rated Real-Time Operating Systems
• Experience with automotive communication protocols (CAN, LIN) and peripheral interfaces (SPI, I2C, UART)
• Comfortable using Git and working in a Linux development environment
• Proficiency with hardware debugging tools (SWD/JTAG, multimeter, oscilloscope, logic analyzer)
• Eligible to work in the United States

Preferred Qualifications

• Experience taking an embedded system from concept to production
• Experience with safety-critical or fault-tolerant systems in automotive, aerospace, or robotics
• Familiarity with ISO 26262 and functional safety concepts
• Experience with modern C++ and/or Rust
• Automotive Ethernet (100M/1G-T1), TSN/gPTP
• Experience with embedded security and/or automotive security
• MISRA C/C++ compliance and static analysis tooling
• Python for test automation and scripting
• Familiarity with HARA, FMEA, and safety-case development
• Experience augmenting firmware development with LLMs while maintaining rigor and responsibility
