Platform Engineer at Mujininc — Tokyo, Japan

About The Role

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.

Responsibilities

Build software that engineers rely on: Develop and improve internal tools and services that support engineers across Mujin.
Shape the developer experience: Work across CI/CD, build tooling, release workflows, documentation tooling, log collection, and internal support workflows.
Work on a broad range of engineering problems: Contribute to both new tools and existing systems, with opportunities to work across Rust, Go, and Python.
Build for modern development environments: Develop and improve tooling and services used in containerized environments, including Docker and Kubernetes.

Minimum Requirements

3+ years of professional software engineering experience
Hands-on experience designing and building software services, command-line tools, developer tools, or internal engineering systems
Professional programming experience with at least one general-purpose language such as Rust, Go, Python, C++, or a comparable language
Experience contributing to software across multiple technical areas or layers of a system
Understanding of software development workflows, including areas such as CI/CD, build systems, testing, deployment, or release processes
Ability to collaborate with engineers and understand the needs of internal users

Preferred Requirements
-
Experience working in a Platform Engineering, Developer Experience, Engineering Enablement, or similar team
-
Experience building tools or services used by a large engineering organization
-
Experience with Rust, Go, or Python
