Software Development Engineer

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.
A Quick Overview of What This Role EntailsAs we continue to grow, scalability is crucial for deploying our products faster and more efficiently. At the center of this effort is our new Cloud Team, formed in November last year to lead this important mission.The Cloud team's mission is to lead Mujin’s global expansion by developing a cloud-based platform that connects and centralizes our edge-computed controllers across factories and warehouses. This platform will provide integrators and users with a user-friendly GUI, enabling them to monitor production remotely. It also simplifies deploying the latest robotic technology on a large scale, making advanced automation more accessible and efficient. As the system is still in its early stages, you’ll have the exciting opportunity to contribute to its design and development from the ground up.
The cloud team’s goalsLet's create a modern cloud service with us by focusing on high availability (HA), automation, and productivity enhancements. Your work will not only improve the team’s efficiency but also have a direct connection to Mujin’s business success.
