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

Benefits

• Competitive compensation package
• Globally diverse workplace
• Exposure to cutting-edge robotics technology
• Visa sponsorship
• Relocation support
• Commuting allowance
• Flexible working hours and dress code policy
• Japanese Social Security (Health Insurance, Pension, Employment Insurance)
