The 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) forms 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 will also support decommissioning activities across other legacy facilities.
This is your chance to contribute to a nationally significant programme with real-world impact.

• 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)

What We’re Looking For

• 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 isn’t a standard technical author role-you’ll be embedded within a live nuclear project, influencing validation and contributing to safety-critical processes. It’s a unique opportunity to combine writing expertise with hands-on engineering collaboration in one of the UK’s most important infrastructure programmes.
