Overview

Mujin develops "MujinController," a platform that leverages a real-time digital twin and advanced robotics to seamlessly connect industrial equipment for fully autonomous operations.

Driven by our unique approach towards Robotics Machine Intelligence (MujinMI), we offer a robust suite of perception, planning, and control algorithms, enabling autonomous robot movement and transforming automation in challenging industrial environments.

Trusted by globally recognized companies, our cutting-edge technology enhances efficiency and innovation across the supply chain. With headquarters in Japan and expanding offices in China, the US, and Europe, Mujin offers a dynamic, fast-growing environment where your work directly shapes the future of automation.

Team Introduction

As a Software Engineer on Mujin's Warehouse Execution System (WES) & Fleet Management (FM) team, you will play a key role in designing, developing, and deploying Mujin’s advanced warehouse execution and fleet management systems. Our team works at the intersection of robotics, automation, and software engineering to optimize warehouse operations and ensure seamless orchestration of robots and industrial equipment.

Responsibilities

  • Design, develop, and maintain WES software to manage warehouse inventory, scheduling, and order fulfillment.
  • Implement and integrate drivers for industrial hardware, including robots, conveyors, 3D cameras, sensors, PLCs, AGVs, ASRS, and WMS.
  • Work with real-time operating systems (RTOS) and network protocols to ensure system efficiency and low-latency communication.
  • Ensure system security by implementing robust encryption and access control mechanisms.
  • Design and optimize high-performance backend services and APIs for seamless integration with third-party warehouse software.
  • Develop and enhance scalable HTTP servers to handle large-scale warehouse operations.
  • Collaborate closely with backend and frontend teams to improve system usability and user experience.
  • Maintain code quality and testing frameworks to ensure high system reliability.
  • Occasionally travel to customer sites, both domestically and internationally, for deployment and support.
  • Tackle complex technical challenges in a fast-paced environment.
  • Take on additional tasks related to the above responsibilities as needed.
  • Minimum Requirements
  • BSc degree or higher in Computer Science, Computer Engineering, or related fields, or equivalent academic or work experience
  • Excellent experience and high proficiency in C++ and Python
  • Advanced Linux user, with excellent experience in Linux software development
  • Expert in Linux internals, networking stack, network protocols, routing, async I/O, Docker and its internal workings
  • Experience in full-stack development
  • Technical communication skills in English
  • Preferable Requirements
  • Expert in real-time OS, Linux kernel module development, EtherCAT
  • Experience in robotic software development
  • Attractiveness
  • We are looking for those who are prepared to dedicate themselves to facing big challenges, work proactively and independently, and take ownership when working with members across the teams!
  • You will get your “hands dirty” working on all aspects of the industrial robot controller, not being confined to a specific component in the system. The work is challenging, mostly like something that you have never done before, requiring extensive research.
  • Since the work is widely applicable, it will affect everyone in the engineering team, making the WES & FM team the likely “go-to” people. You will have chances to travel and work onsite to integrate cutting-edge industrial systems such as AGVs and ASRS.
