Head of Documentation / Lead Documentation Engineer

Mujin creates MujinOS, the intelligent operating system for industrial robotics. By leveraging real-time digital twins, MujinOS seamlessly connects and orchestrates equipment to achieve fully autonomous operations.

At our core is  Machine Intelligence (MujinMI), a unique approach offering advanced perception, planning, and control algorithms that solve the most challenging automation problems.

Trusted by globally recognized companies, we are redefining supply chain efficiency. Headquartered in Japan with growing teams in China, the US, 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, 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.
