Unity Technologies: Software docs from start-up to enterprise
Over nine years at Unity Technologies I grew from an individual contributor to Chief Technical Editor, and helped scale the documentation team from 4 to 60 writers. I built the writing guidance and quality standards that still define Unity's documentation today, working across technical documentation, training videos, blog posts, and internal communications. I also mentored junior writers and produced company-wide training materials on technical communication.

Testimonials
"You’ve made such a huge, lasting impact in documentation over the years. I probably speak for everyone you’ve worked with when I say we wouldn’t have come as far as we have without you, in what has historically been an uphill battle. Thank you for all of your contributions."
— Technical Product Manager
"Our collaboration has always been great and it has always been great to have someone around who really understands the area. Your way of being able to translate our ramblings always seemed like wizardry."
— Software Engineer
"You’ve been instrumental in establishing documentation at Unity, and we wouldn’t be where we are now without you helping to set us on the right path."

Now Prototype It: GOV.UK docs for a new audience
Documentation and content work on an organisation-agnostic fork of the GOV.UK Prototype Kit, covering technical documentation, UX and web copy, and trade show messaging. I rebuilt documentation that had only covered the tool's divergence from its GOV.UK source into a standalone docset that supports users from any organisation, and translated a technical prototyping tool into content that worked for engineering and non-technical audiences alike.
I delivered a Docusaurus-based site from the project's GitHub repo, covering the end-to-end process of users' most common tasks.

APCOA UK: Internal developer docs from scratch
Engaged as a technical writer and documentation strategist to build internal developer documentation to support the onboarding of new software engineers. This was also a knowledge management role, taking information from across the company and making it discoverable to all engineers.
I delivered an MkDocs-based site on Azure DevOps, covering three major internal systems. Work included restructuring reference documentation for a code generation system and its modifier files, creating onboarding tutorials, standardising C4 architecture diagrams in Mermaid, documenting website architecture, and bringing runbook standards into line across EU and UK deployments. I also built an AI prompt set anchored to Good Docs Project templates, so that the team could sustain documentation quality after the contract ended.
Testimonials
"Siobhan brought an impressive combination of technical writing expertise, infectious positivity, and organisational superpowers to the team. Her upbeat energy, collaborative approach, and talent for helping the unorganised become organised makes her an invaluable colleague and a genuine pleasure to work with."
— Senior Software Developer
"Thanks for all your help Siobhan, we are in a much better place now, and I think we can all take on the challenge of bringing the now-existing documentation up to the standards that have been set out."
— Senior Software Developer
"We found this a very useful experience and exercise. That the whole team has engaged and bought into the process hopefully means that we'll carry on the good fight."

Skiller Whale: Programmer training courses for engineers
Course research, structure, and writing for a live-coached workshop on pair programming, produced for an e-learning provider specialising in live technical coaching for software engineers.
Working alongside a subject-matter expert who provided the technical depth, I led the research, structure, and writing. I designed the course around information-architecture principles, moving from what pair programming is, through its social and working models, to its application in TDD and the challenges of adopting it. I treated it as a course in communication as much as technique, on the understanding that social cohesion is what actually drives adoption. The result is a 90-minute live-coached workshop, now a standing part of Skiller Whale's catalogue.
