Technical Author

Technical Author Milton Keynes (1 day/week on-site) | 4-Month Contract | £350/day (Inside IR35)
We're looking for a Technical Author to join a financial services technology team, focused on producing clear, accurate documentation for complex API and SFTP-based data products.
The Role
You'll take ownership of documentation for a data integration platform, working closely with product owners, QA, and developers to translate complex technical detail into clear, structured content for both technical and non-technical audiences. This is a hands-on role covering everything from functional specifications through to release notes and FAQs, with the scope to also shape how documentation is created and maintained going forward.
What You'll Do

Review existing functional specifications (API & SFTP) to identify gaps and ambiguity
Work with the Data Quality team to translate identified trends into clear, closed-gap documentation
Establish standardised naming conventions and terminology
Produce updated functional specifications for a data platform
Create supporting documentation for customers and internal stakeholders - release notes, FAQs, and related materials
Plan documentation structure, information architecture, and navigation flows
Edit and maintain consistency of tone, style, formatting, and terminology across all outputs

What You'll Bring

Strong technical writing, editing, and communication skills, with the ability to make complex topics accessible
Proven experience producing documentation for software, APIs, cloud, or similar technical products
Comfortable working within Agile/iterative delivery environments and cross-functional teams
Working knowledge of Markdown editors (VS Code, Obsidian), documentation generators (Sphinx, Docusaurus), and Git/GitHub
Experience with Mulesoft/Anypoint products is a strong advantage
Diagramming experience (e.g. Visio) useful for supporting content
Understanding of UX writing, content design, or information architecture is desirable

Bonus Points
Experience building style guides, reusable documentation templates, or a central technical glossary - this role has scope to establish these from scratch.
You Are
Detail-oriented, user-focused, and comfortable managing multiple documentation projects at once. You're curious about new tools, happy working independently, and equally comfortable collaborating with developers, QA, and product stakeholders.
