About Rapyuta Robotics 

We build robots that do the work people shouldn’t have to — physically demanding, repetitive, and dangerous tasks in warehouses and logistics operations worldwide. Our PA-AMR is Japan’s most deployed pick-assist robot. Our ASRS platform won the Good Design Award Gold 2024. Our cloud robotics platform, rapyuta.io, coordinates fleets of heterogeneous robots at scale. 

The engineering challenge is real: robots operating in uncontrolled environments, under production load, with humans nearby. The embedded software stack — from bare-metal MCU drivers to real-time control loops to hardware abstraction layers — has to be correct, observable, and recoverable when things go wrong in the field. If you want to see your code move something physical in the real world, this is the work. 

We’re a team of 300+ across 20+ countries, and we’re building toward a future where automation handles the dull and dangerous so people can focus on what actually takes human judgment. 

 The Role 

As a Senior Embedded Software/Systems Engineer, you will closely collaborate with Electronics Engineers, Embedded Systems Engineers, and Robotics Software Engineers to push the boundaries of mechatronics on our autonomous mobile robot platform. 

Your responsibilities include: 

• Device driver development — Creating and optimizing device drivers for sensors, actuators, memory units, and computational units across our MCU and Linux-based platforms 

• Communication pipeline implementation — Designing and implementing intra- and inter-processor communication pipelines for memory- and compute-constrained devices 

• Robotic systems design — Contributing to embedded software architecture across the full stack: bare-metal firmware, RTOS configuration, hardware abstraction, and host-side platform libraries 

• Integration and bring-up — Collaborating with electronics engineers on board bring-up, schematic review, and hardware-firmware co-debugging 

• Automation and CI — Driving development of build, flash, and test automation for embedded targets 

• Mentorship — Technical leadership and mentoring of junior engineers; contributing to team-level design and code review standards 

Requirements

Minimum Qualifications 

• 5+ years of embedded systems product development with proven ownership of 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, RS232/RS485 

• Linux system-level programming and administration 

• Device driver development — Linux kernel drivers or bare-metal peripheral drivers 

• Debugging with oscilloscope, logic analyzer, and JTAG/SWD 

• Schematic reading at a complex level 

• Strong debugging and problem-solving skills with interrupt-driven designs 

Preferred Qualifications 

• Python for tooling, test automation, or data analysis 

• Familiarity with Docker, CI/CD, ROS1/ROS2, micro-ROS 

• SoC-level software optimization 

• Japanese language proficiency 

What We Value in This Role 

Beyond technical qualifications, the behaviors we look for: 

• Ownership — you drive outcomes, not just tasks; you know what would break if you weren’t there 

• First principles — you question inherited assumptions and derive solutions from actual constraints 

• Systems thinking — you understand the full data path from sensor to actuator, not just your module 

• Failure-first design — safe states and fault handling are designed in, not added after the first incident 

• Communication — you write design documents that 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)
