About Rapyuta Robotics

Rapyuta Robotics Koto-ku, Tokyo

Building low­ cost, lightweight autonomous mobile robots with high-level intelligence distributed in the cloud, and enabling such robots to offload some of their heavy computation and seamlessly learn and share experiences with one another.

Key benefits

  • Open, inclusive, safe environment
  • There's always something to learn
  • Relocation support

About the position

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.

Responsibilities

  • 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

  • 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

Nice to haves

While not specifically required, tell us if you have any of the following.

  • Python for tooling, test automation, or data analysis
  • Familiarity with Docker, CI/CD, ROS1/ROS2, micro-ROS
  • SoC-level software optimization

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
