Technical Author -Sellafield

Overview

Technical Author – Location: Sellafield Site, Cumbria. 3 days per week on-site (likely to increase). Security Clearance: SC (P4 Pass required). Rate: £50-56/hour Inside IR35.

Opportunity

We're supporting a major programme at Sellafield and are looking for a Technical Author to join a critical nuclear project at the forefront of the UK's clean‑up mission. The Box Encapsulation Plant (BEP) is a key part of the Magnox Swarf Storage Silo (MSSS) Programme, one of the most important hazard‑reduction initiatives on the Sellafield site. This project will safely treat and immobilise nuclear waste, preparing it for long‑term storage, and support decommissioning activities across other legacy facilities.

What You'll Be Doing

• Developing and finalising Operation & Maintenance (O&M) manuals for BEP systems.
• Working closely with engineering teams to ensure accuracy and clarity of technical documentation.
• Taking a proactive role in validation activities, ensuring documentation reflects real‑world operation.
• Supporting aspects of the risk assessment process, contributing technical insight where required.
• Delivering high‑quality technical authoring services under a time‑based contract (NEC3 PSC - Option E).

Qualifications

• Strong technical writing skills, ideally within engineering or nuclear environments.
• Ability to interpret complex engineering information and translate it into clear documentation.
• Experience working with O&M manuals or similar technical documentation.
• Comfortable working on‑site in a regulated, high‑security environment.
• Existing SC Clearance with P4 Pass (or ability to obtain quickly).

Additional Details

Based on‑site at Sellafield (SL accommodation – likely C1003). Initial requirement of 3 days per week on‑site, increasing as the project progresses. Role operates as a directed resource, supporting delivery under the BEP Joint Venture.

Why Apply

This is not a standard technical author role – you'll be embedded within a live nuclear project, influencing validation and contributing to safety‑critical processes. It offers a unique opportunity to combine writing expertise with hands‑on engineering collaboration in one of the UK's most important infrastructure programmes.
