Embedded Software Engineer - Robotics

We are committed to our core value of “Empathy,” aiming to automate demanding, dirty, and dangerous jobs, and create a society where people can engage in more intellectual and creative work. By developing and supporting the implementation and operation of robotics platforms and robot solutions utilizing the world’s most advanced control and coordination technologies, we strive to realize this vision.
In this position, you will be working with our Embedded team to help drive innovation and optimization in the real-time software that runs on our autonomous mobile robots and ASRS platform. You will manage key parts of our embedded stack, including MCU drivers, control loops, and hardware abstraction layers, owning them end to end from design through implementation, testing, and field debugging alongside our Electronics, Embedded Systems, and Robotics Software engineers.
Key responsibilities:
Designing and implementing firmware modules: communication protocol handlers, sensor drivers, state machines, and diagnostic subsystems
Debugging hardware-software boundary issues using oscilloscope, logic analyzer, JTAG/SWD, and bus analysis tools
Reading and interpreting electronic schematics independently
Choosing RTOS primitives deliberately – understanding ISR constraints, priority inversion, and concurrency failure modes
Contributing to embedded software architecture across the full stack: bare-metal firmware, RTOS configuration, hardware abstraction, host-side platform libraries, and real-time control loops.
Writing design documents that explain why decisions were made, not just what was implemented
Requirements
Minimum Qualifications
5+ years of embedded systems product development with shipped hardware
Proficiency in C and C++ for embedded systems
Hands-on experience with microcontrollers (ARM Cortex-M or equivalent)
RTOS experience in production: Zephyr, FreeRTOS, or equivalent – task scheduling, ISR constraints, concurrency primitives
Experience with communication protocols: I2C, SPI, CAN, UART
Schematic reading – can navigate a PCB schematic to trace a signal path without guidance
Debugging with oscilloscope, logic analyser, and JTAG/SWD
What We Value in This Role
Ownership – you hold a module end to end; you know what breaks if you aren’t there
First principles – you question inherited assumptions and verify constraints from the ground up
Systems thinking – you understand the full data path from sensor to actuator, not just your layer
Failure-first design – safe states and fault handling are designed in, not added after the first incident
Communication – your design documents help the next engineer understand the why, not just the what
