Release Manager / Release Engineer

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 Release Engineer for a growing team to focus on shaping and building scalable, reliable processes for software packaging, validation, and delivery rather than just building features. Regular releases are critical to maturing MujinOS as a product, ensuring consistent quality and completeness across complex systems. Turning ongoing development into stable, releasable versions requires not only coordination, but also development of internal tooling, workflows, and automation systems . In this role, you will make releases more predictable, efficient, and scalable by designing and developing release workflows, internal tools, and quality gates—while staying hands-on with release-stage QA and integration validation. You will work closely with engineers responsible for our core software systems, QA, and documentation owners, helping ensure that what is built can be confidently released, clearly understood, and effectively used by both internal teams and end users.
