Technical Writer / Technical Editor

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. The Mujin Controller is a highly complex and innovative robotics platform used by developers, integrators, and operators around the world. Clear, accurate, and accessible documentation is essential for enabling customers to use the system effectively and for scaling global deployments. The Technical Writer / Technical Editor is responsible for producing and maintaining high-quality documentation, ensuring consistency across all user-facing materials, and shaping how different audiences understand and interact with the Mujin Controller. This role works closely with engineering, product, and support teams to transform technical knowledge into a coherent, user-centered information experience. Responsibilities:

Write, edit, and maintain high-quality documentation for developers, integrators, operators, and end users  (e.g., API references, tutorials, release notes, troubleshooting guides, UX copy)

Collaborate with engineers, product managers, and UX designers to extract technical information and produce clear explanations

Define and maintain documentation standards, style guides, terminology, and voice/tone guidelines

Plan and structure documentation sets for new features, releases, and product areas

Assist in internationalization and localization workflows to ensure documentation quality in multiple languages

Analyze feedback from internal teams and customers and improve documentation usability and discoverability

Review and improve UI text, warnings, labels, and onboarding flows for the web-based controller UI

Requirements:

Excellent writing and editing skills, with the ability to explain complex concepts clearly and concisely

Strong understanding of software development concepts, APIs, and modern development workflows

Awareness of how “classical” industrial automation systems (PLC-based environments, hardware-centric systems, industrial HMIs, etc.) are traditionally documented

Ability to translate between classical industry expectations (step-by-step procedures, safety-oriented documentation, hardware-first thinking) and modern software-style documentation

Experience creating technical documentation in a fast-paced software environment (developer docs, API references, system architecture descriptions, etc.)

Familiarity with documentation tools and workflows (Markdown, static site generators, git, CI-based publishing)

Ability to collaborate with engineers and product teams and ask the right questions to uncover technical details

Ability to read and understand code examples (e.g., Python, JavaScript/TypeScript)

Preferred Skills and Competencies:

Professional experience in industries such as robotics, manufacturing automation, logistics systems, or with users transitioning from PLC/HMI environments

Experience editing or reviewing automatically generated documentation (e.g., from OpenAPI, Sphinx, Doxygen, or custom pipelines)

Understanding of compliance-oriented industrial documentation (e.g., safety instructions, lock-out/tag-out procedures, operational workflows) and how these expectations differ from modern software documentation

Experience with UX writing or product copy editing

Experience with information architecture, docs-as-code practices, or content strategy

Experience working with Linux and command-line tools

Experience working in multilingual / localization pipelines

Familiarity with Docker, CI/CD, and software build systems

Experience in programming languages (C++, React/TypeScript, etc.)

Experience creating developer-focused content such as tutorials, samples, and troubleshooting guides

Attractiveness

Work at the intersection of engineering, product, UX, and support to shape the entire customer information experience

Influence the usability and adoption of a cutting-edge robotics platform used globally

Collaborate with highly skilled teams across multiple disciplines

Gain exposure to modern documentation automation, code-driven docs workflows, and advanced tooling

Opportunities to expand into areas such as information architecture, UX writing, developer education, and product design

Contribute directly to making the Mujin Controller more accessible, efficient, and delightful for all users
