Platform Engineer (Developer Productivity / Build Optimization)

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 Senior Software Engineer focused on improving the development and build processes of large-scale robotics software systems.

This role is not limited to CI/CD operations. You will identify fundamental bottlenecks in the development workflow, such as slow builds, unreliable dependencies, and complex build configurations, and solve them at the build system level.

This role is a strong fit for engineers who have worked on engineering productivity, developer platforms, or internal tooling teams, where they improved build or development workflows at a system level, beyond simply operating CI/CD pipelines.

You will work on designing and evolving the build system itself to improve developer productivity, reproducibility, and scalability across large C/C++ codebases.

Examples of challenges you may work on

• Reducing build times from hours to minutes by redesigning the build system.
• Re-architecting dependency management to remove hidden coupling between modules.
• Improving build reproducibility across local and CI environments.

Responsibilities

• Analyze existing build systems and propose structural improvements or migrations where necessary
• Design and implement a modern and optimized build system, adhering to best practices and coding standards.
• Create early prototypes and write technical documentation to propose system changes.
• Manage and improve the CI infrastructure and tools.
• Ensure good coding practices and code quality through consistent code reviews.
• Collaborate with other engineering teams to improve and optimize the CI tools.

Minimum Requirements

• Understanding of C/C++ compilation processes and build tools (such as CMake).
• Experience working on developer productivity, platform engineering, or internal infrastructure teams.
• Experience integrating and operating 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 and Linux administration (Debian preferred).
• Experience operating containerized environments (such as Docker, k8s, etc).
• Proficiency with Git version control and collaborative branching workflows.
• Experience in planning and executing infrastructure projects or system migrations.

Preferred Requirements

• 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.
