Full job details

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.


About the Role

Mujin is hiring a Platform Engineer to join our Engineering Enablement team and help build the internal services, tools, and workflows that enable engineers to develop, test, release, and support software effectively.

This is a software engineering role focused on improving the developer experience across a broad range of areas, including CI/CD, build tooling, release workflows, internal support workflows, documentation tooling, and log collection. Rather than focusing only on operating infrastructure, you will design and develop services, command-line tools, and automation used by engineering teams across Mujin.
