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.
We are looking for a Head of Documentation / Lead Documentation Engineer to own the documentation system, tooling, and processes for Mujin OS - a complex software product in the industrial automation/robotics domain.
This role is responsible not only for writing and editing documentation, but for designing, implementing, and maintaining a sustainable documentation ecosystem that is deeply integrated into our engineering workflows. It owns documentation as a system and acts as the central point of accountability for documentation structure, tooling, and quality.
The ideal candidate has extensive writing experience as well as hands-on experience setting up docs-as-code systems, partnering closely with engineers, and enabling documentation to be authored, reviewed, and maintained across teams.
This role is intended to evolve into building or leading a documentation team over time.
Responsibilities:
Documentation Strategy & Ownership
- Own the end-to-end documentation strategy, including structure, standards, tooling, and long-term maintainability
- Define documentation audiences, document types, and information architecture (e.g. developer docs, operator manuals, API references, conceptual guides, internal docs)
- Act as the single accountable owner for documentation quality, consistency, and discoverability
Docs-as-Code & Tooling
- Design and maintain a docs-as-code workflow (e.g., Markdown/AsciiDoc, git-based authoring, CI-driven builds and previews)
- Select, configure, and evolve documentation tooling (static site generators, linters, preview environments, versioning strategies)
- Integrate documentation into the software development lifecycle, including PR-based documentation changes, release documentation, and versioned documentation tied to product releases
Automation & Generated Documentation
- Define what documentation should be:
- Written manually
- Authored by engineers
- Automatically generated from source (APIs, schemas, configs, code)
- Set up and maintain pipelines for generated documentation (e.g. OpenAPI, Sphinx, Doxygen, or custom tooling)
- Ensure generated documentation is usable, curated, and integrated into the overall documentation set
Collaboration with Engineering & Product
- Work closely with engineers, product managers, and UX designers to extract and validate technical information as well as define documentation responsibilities per component or feature
- Enable and guide engineers to contribute documentation through templates, contribution guidelines, review processes
- Establish clear expectations for documentation ownership and updates as part of feature development
Writing, Editing, and Review
- Write and edit high-impact documentation where structure, clarity, or system-level understanding is critical
- Review and improve API documentation, tutorials and onboarding materials, troubleshooting guides, release notes
- Review and improve UI text, warnings, labels, and onboarding flows for the web-based controller UI
Standards, Quality, and Governance
- Define and maintain documentation standards, style guides, terminology, and voice/tone guidelines
- Establish review and quality assurance processes for documentation changes
- Balance modern software documentation practices with industrial documentation expectations, including safety-related content where applicable
Internationalization & Scaling
- Design documentation workflows that support internationalization and localization
- Collaborate with localization teams or vendors to ensure technical accuracy across languages
- Prepare the documentation system to scale with product complexity and team growth
Requirements:
- Significant experience owning or leading documentation for a complex software product
- Excellent writing and editing skills, with the ability to explain complex systems clearly and precisely
- Hands-on experience with docs-as-code workflows (git-based authoring, CI-based publishing)
- Strong understanding of software development concepts, APIs, and modern development workflows
- Ability to work as a peer with engineers and discuss architecture, interfaces, and trade-offs
- Awareness of how classical industrial automation systems (PLC-based environments, hardware-centric systems, industrial HMIs) are traditionally documented
- Ability to translate between classical industry expectations (procedural, safety-oriented, hardware-first documentation) and modern software-style documentation (conceptual models, APIs, workflows, examples)
- Experience documenting systems used by engineers, integrators, and operators with differing expectations
- Experience defining documentation standards and enforcing them across teams
- Ability to drive adoption of documentation practices without relying on formal authority
- Comfortable acting as a process designer and change agent, not just a content producer
Preferred Skills and Competencies:
- Professional experience in robotics, manufacturing automation, logistics systems, or adjacent industrial software domains
- Experience designing or maintaining documentation platforms rather than only contributing content
- Experience with Markdown, AsciiDoc, static site generators
- Experience with CI/CD systems
- Experience editing or curating automatically generated documentation
- Understanding of compliance-oriented or safety-adjacent documentation and how it intersects with software documentation
- Experience with information architecture, content strategy, or developer experience (DX)
- Ability to read and understand code (e.g. Python, C++, JavaScript/TypeScript)
- Experience working with Linux and command-line tools
- Familiarity with Docker, CI/CD pipelines, and software build systems
- Experience working in multilingual documentation environments
Why This Role Matters
- Our product is replacing and redefining traditional industrial automation systems. The documentation must therefore bridge decades of industry expectations while supporting modern, software-driven workflows.
