Jobs in Tokyo, Japan

About the role

The team is currently small, and you will play a key role in owning the architecture, evolution, and technical direction of Mujin's large-scale C/C++ build systems. This role focuses on build-system architecture, dependency management, build performance, developer productivity, and long-term maintainability. While CI/CD infrastructure is an important supporting component, this is primarily a build-systems engineering role rather than a DevOps or release-engineering position.

What you'll bring

• Experience owning or driving the architecture of large-scale C/C++ build systems.
• Deep understanding of build-system architecture, dependency management, compiler toolchains, linkers, build reproducibility, and build-performance optimization.
• Strong knowledge of CMake and modern C/C++ build environments.
• Experience integrating build systems within CI/CD pipelines.
• Proficiency in at least one programming language used for internal tooling (Python or Go).
• Working knowledge of Bash scripting, Linux administration, and containerized environments (Docker, Kubernetes, etc.).
• Proficiency with Git version control and collaborative development workflows.
• Hands-on experience with Bazel, JHbuild, or Gnome build tools, or building complex, distributed build systems.
• Knowledge of package management systems across multiple languages (Python, C++, Rust, or JavaScript).
• Experience with Kubernetes
• Experience writing technical proposals and design specifications.
• Familiarity with Agile software development.
