Job description

Era4 develops, owns and operates AI infrastructure across the UK, powered by renewable energy. Converting legacy industrial and energy sites into modern data‑centre facilities, Era4 is combining brownfield regeneration opportunities with cleaner, efficient, scalable compute capacity for healthcare, research, finance, enterprise, and public‑sector organisations.

We are seeking a Technical Writer to support the creation and maintenance of clear, structured documentation across our platform and infrastructure. You will work closely with engineering, platform, and product teams to translate complex technical concepts into accessible content for internal teams and customers.

This role is hands‑on and delivery‑focused, ideal for someone who can bring structure to fast‑moving environments and improve how knowledge is captured and shared.

Key Responsibilities:

• Create and maintain technical documentation including platform guides, onboarding materials, runbooks, and operational procedures.
• Work with engineering and platform teams to document systems, workflows, and APIs.
• Translate complex infrastructure and platform concepts into clear, user‑friendly content.
• Support customer‑facing documentation such as user guides and knowledge base articles.
• Maintain and improve documentation repositories (e.g., Confluence, Git‑based docs, Notion).
• Apply consistent standards, templates, and formatting across documentation.
• Keep documentation up to date as systems evolve, ensuring accuracy and usability.
• In depth experience as a Technical Writer in a software, cloud, or infrastructure environment.
• Strong ability to understand and explain technical systems (e.g., cloud platforms, Kubernetes, networking fundamentals).
• Experience working with engineers and product teams to produce documentation.
• Clear and concise writing style with strong attention to detail.
• Familiarity with documentation tools such as Markdown, Git, Confluence, or similar.
• Comfortable operating in a fast‑paced, evolving environment.

One or more would be an advantage:

• Exposure to AI/ML platforms or GPU‑based infrastructure.
• Familiarity with Kubernetes or container‑based platforms.
• Experience documenting APIs or developer‑facing products.
• Understanding of data centre environments (compute, storage, networking).
• Experience in a startup or scaling organisation.

Why Join Era4:

You’ll be joining a mission‑driven start‑up building critical national infrastructure, where operational excellence directly enables growth. This role offers high visibility with leadership, real autonomy, and the chance to shape how a next‑generation company operates at scale.
