Cloud Platform Engineer (Go, Kubernetes)

Mujin is a global leader in industrial automation, redefining supply chain efficiency through MujinOS—our intelligent operating system for robotics. At our core is Machine Intelligence (MujinMI), a unique approach that leverages real-time digital twins and advanced perception, planning, and control algorithms to achieve fully autonomous operations.

Our flagship product, MujinController, empowers users with a highly configurable, no-code interface. By integrating cutting-edge motion planning and computer vision, it enables seamless automation for complex applications such as palletizing, picking, and truck unloading.

Headquartered in Japan with a growing presence in the US, China, and Europe, we invite you to join a dynamic environment where you can shape the future of automation.

A Quick Overview of What This Role Entails

Mujin Portal is a cloud-based product that enables customers and Mujin engineers to manage and support Mujin robotic systems deployed across multiple sites.

Portal runs in multiple regions across Japan and the US, on AWS and on our own Kubernetes clusters, and keeps a persistent connection to every Mujin Controller in the field. As the fleet grows, the platform underneath Portal matters as much as the features on top of it: how we deploy, how we scale across regions, how we observe and secure it, and how we keep it running when something breaks.

As a Cloud Platform Engineer, you will own that platform. You will write Go alongside the rest of the team, but your focus is the infrastructure, deployment, reliability and security of Portal and the services around it.
