Role
Who you are
- Built technical documentation in a fast-paced software environment that improved adoption or reduced support queries
- Applied AI/automation (e.g. LLMs, workflow tools like Zapier/n8n, Grammarly, Claude, or similar) to streamline content workflows or improve quality
- Designed or restructured documentation systems to be scalable, maintainable, and discoverable
- Partnered with engineers, product managers, or customer teams to capture technical detail and translate it for diverse audiences
- Established or championed standards for tone, style, and structure, ensuring consistency across multiple contributors
- Owned end-to-end delivery of documentation projects, from requirements gathering through to validation and rollout
- You’re unlikely to thrive here if:
- You prefer static documentation over evolving, AI-driven workflows, showing proactiveness and bringing meaningful change
- You shy away from experimenting with AI tools and workflows, and reluctant to learn new approaches
- You are uncomfortable taking ownership of standards, quality, and consistency in your work
What the job involves
- At hx, world-class documentation is a product in its own right: it drives adoption, enables customer self-service, and reduces friction for internal teams. As our products scale and our AI agents depend on well-structured knowledge, documentation becomes a critical part of how we deliver clarity and confidence to users
- This role will sit at the intersection of engineering, product, and customer teams, creating and governing documentation that is accessible, structured, and AI-ready. You’ll be building this function from the ground up – our first dedicated technical writer – so you’ll shape both the standards and the workflows that support adoption across hx
- You’ll work hands-on to design documentation systems, implement AI-assisted authoring, and enforce consistency across diverse content sources. With the freedom to experiment and the backing to scale your ideas, you’ll create lasting impact for both internal teams and global clients
- Designing and delivering structured, AI-powered documentation that makes hx products easy to understand, adopt, and scale
- Implementing documentation standards, workflows, and governance across teams to ensure consistency and discoverability
- Partnering with engineering, product, and customer teams to capture knowledge and translate it into accessible, high-impact content
- Building content pipelines and structures that support AI-powered search, question-answering, and automated validation
- Introducing and refining automation and feedback mechanisms to continuously improve documentation quality
- Driving adoption of documentation practices that reduce support needs and accelerate onboarding for users

Our take
hyperexponential was created to provide modelling software to help people and businesses build, deploy and manage analytical models that work with small, sparse and fragmented datasets. Its goal is to make teams more agile, collaborate more deeply, and work more productively.
hyperexponential's pricing and data-driven decision-making software is built for the speciality and commercial insurance markets. The product has broad applications, but the company's initial focus is on speciality insurance, a sector the founders know well, having worked there for more than a decade.
The company's making a name for itself too, working with some of Europe's biggest insurers to transform how pricing decisions are made. And its newest launch, hx AI, blends powerful AI with its core platform to help insurers build smarter models, faster. It's a strong signal that hyperexponential is not just growing, but ready to lead the way.
