Technical Writer

The problem we saw

Most AI infrastructure is built for batch: send a query, wait, get a response, reset. Powerful, but transactional. AI is becoming interactive — sessions that hold state, models that stay alive between turns, generation that responds as it runs — and the infrastructure to deliver that at scale doesn't really exist yet.
The bottleneck isn't the models anymore. It's the infrastructure underneath them.
What we're building to fix it

uRun is the inference cloud for interactive AI: the compute layer that makes real-time, stateful inference possible at scale. We came out of stealth in April 2026, are backed by top-tier investors, and are founded by Keegan McCallum, who scaled inference infrastructure for some of the most demanding generative AI workloads in production.
We're an infrastructure company. We build the layer that model labs, builders, and research teams ship on top of.
Where you come in

Infrastructure is only as powerful as the developers who can use it. As uRun's first Technical Writer, you will own the entire documentation surface: API references, integration guides, SDK docs, conceptual explainers, and the developer experience that ties it all together.
This is a founding hire. You will build the documentation foundation from scratch, work directly with engineers to get inside the product, and set the standard for how uRun communicates with the developers who build on top of us. The quality of your work is a direct part of our product.
What you'll actually be doing day-to-day

Own the full documentation lifecycle end-to-end: plan, write, review, publish, and iterate across API references, quickstarts, integration guides, and conceptual docs

Embed with engineering to understand the product deeply, translating complex distributed systems and inference infrastructure concepts into clear, accurate developer documentation

Build and maintain the docs infrastructure: tooling, structure, versioning, and publishing pipeline

Write and maintain SDK documentation and code samples across multiple languages, ensuring they are accurate, tested, and developer-friendly

Create onboarding and integration content that helps developers go from zero to production on uRun as fast as possible

Partner with the GTM and engineering teams to produce technical content that supports developer adoption: tutorials, explainers, changelog entries, and release notes

Establish and maintain a documentation style guide and content standards that scale as the team grows

What skills you need for the journey

5+ years of technical writing experience, with a portfolio that demonstrates clear, accurate documentation for developer or infrastructure products

Strong command of API documentation: you have written reference docs, OpenAPI specs, or equivalent and understand what developers actually need from them

Comfortable reading and writing code: you can work through a code sample, spot an error, and write accurate examples in at least one language (Python preferred)

Experience owning docs infrastructure: static site generators, docs-as-code workflows, version control, and CI/CD for documentation

Strong editorial instincts: you write with precision, cut ruthlessly, and know the difference between explaining and obscuring

Able to operate independently as the first and only technical writer, setting standards without a template to follow

Comfortable working closely with engineers and translating highly technical concepts for a developer audience

Things that will give you an edge

Experience documenting infrastructure, cloud, or developer platform products (compute, networking, storage, or equivalent)

Familiarity with ML infrastructure concepts: model serving, inference APIs, GPU compute, or distributed systems

Experience with docs tooling such as Mintlify, Readme, Docusaurus, or similar

A background that includes developer relations, developer advocacy, or direct experience as a software engineer

Prior experience as a founding or sole technical writer at an early-stage company

What you'll get in return

Competitive salary and meaningful equity in an early-stage AI infrastructure company. The band above is our target; for an exceptional candidate we'll go higher. Equity is real — you're early, and the grant reflects that.
Health, dental, and vision — full coverage

401(k) — company-supported retirement savings

FSA/HSA — flexible spending accounts for healthcare costs

Paid time off — we trust you to manage your time

Top-tier tooling — access to the best AI tools available: Claude, Codex, Kimi, and whatever else helps you move faster

MacBook Pro and AirPods — the hardware you need, on us

How we work (and what that feels like day-to-day)

We build the stage, not the show. We're an infrastructure company, a developer-tools company, and a production partner for model labs — and focus is a deliberate choice we've made and hold to.
Day-to-day, that means a small team, a high bar, and real ownership. You won't wait for permission or inherit a backlog of someone else's decisions. In a founding technical writing role, the docs are what you make them.
It also means ambiguity: priorities shift, not everything is documented yet, and you'll often be the person who decides what "clear enough for now" means. That suits some people and not others, and we'd rather you know that before you apply.
