Technical Writer (Part Time)

About the role

Documentation is a product at Prior Labs. You will build our technical documentation practice from the ground up, improving and expanding what we have, establishing an AI-assisted docs process, and ensuring that our open-source repositories, API, and products are always well-documented.

What you'll do

• Audit, rewrite, and expand our existing documentation across our open-source repositories (TabPFN, tabpfn-extensions, tabpfn-client) and API reference.
• Author new content including tutorials, how-to guides, conceptual explainers, and real-world use case examples targeted for ML practitioners and data scientists.
• Design and implement a modern, AI-assisted documentation workflow using our current stack (GitHub, Linear, Mintlify) to keep docs in sync with code changes.
• Work closely with engineers to translate complex model behaviour and API design into clear, accurate developer-facing content.
• Own the docs roadmap and prioritise improvements based on user feedback and product changes.

What you'll need

• 3+ years of technical writing experience, ideally for developer tools, ML platforms, or open-source projects alongside engineering teams in a fast-moving startup or research environment.
• Hands-on experience with docs-as-code workflows: Markdown, Git, pull requests, and CI/CD-integrated documentation pipelines.
• Strong technical writing fundamentals: clear structure, consistent terminology, audience-aware tone.
• Familiarity with AI-assisted writing tools and experience integrating them into documentation workflows.
• University level Python to produce relevant example code to be used in live documentation.
• Solid understanding of machine learning concepts, especially supervised and unsupervised learning, enough to write confidently for an ML-practitioner audience.

Nice to have

• Prior experience setting up a documentation system from scratch, including style guides and contribution guidelines.
• Experience with video or visual content creation (screencasts, diagrams, interactive notebooks) as a complement to written docs.
