Mechanical Maintenance Fitter
Step into a role where your expertise keeps our Winfrith site running safely, smoothly, and at peak performance. We’re looking for someone ready to take ownership of delivering a first‑class maintenance and breakdown service across our operational areas and wider facility, ensuring every task meets the highest standards of safety, compliance, and efficiency. If you’re driven by precision, thrive in a fast‑paced environment, and are committed to upholding rigorous procedures, regulations, and site licence requirements, this is your opportunity to make a real impact.
What will you be doing
In this role, you will be responsible for maintaining a safe and secure working environment by actively identifying safety, environmental and information security risks, applying STAR principles, and reporting any unusual occurrences. You’ll keep your knowledge of local and NRS management systems up to date while taking the lead on developing and maintaining your own skills, training, and authorisations. Your day‑to‑day work will include carrying out planned preventative maintenance in line with facility instructions, completing corrective works when required, and responding swiftly and safely to breakdowns. You will also operate a range of plant and equipment, often computer‑controlled, while keeping accurate records, performing mechanical or remote handling tasks, and wearing various types of protective equipment as needed.
Alongside hands‑on maintenance and operational responsibilities, you will produce accurate post‑maintenance records, contribute to ongoing reviews of facility maintenance documentation, and support the supervision of contractors working within the facilities. Building and maintaining strong stakeholder relationships will be key, as will supporting the deployment of company-wide policies, processes, and systems to ensure continuous compliance. This includes adherence to the company’s Equality and Diversity Policy and undertaking any associated learning and development activities to support a positive and compliant working environment
Who are we looking for
The ideal candidate will bring a strong foundation in mechanical maintenance, with experience in pressure systems and general plant maintenance as an essential requirement. You must also be competent in using protective clothing and equipment and possess a solid awareness of safe working practices. While not mandatory, a time‑served mechanical apprenticeship and technical qualifications such as City & Guilds, BTEC or NVQ Level 3 (or equivalent) would be advantageous. Additional desirable experience includes machine shop practices, electrical work, and familiarity with maintenance activities within a nuclear or similarly regulated environment.
A background in diverse maintenance operations will be highly valuable. This includes heating and ventilation servicing, wastewater and sewage pump installation and repair, pressure testing pipework, compressor and IC engine servicing, and maintenance of generators, pumps, and towed vehicles. Experience working within confined spaces and carrying out a wide range of general maintenance and repair activities is also beneficial. Overall, the successful candidate will be someone who brings strong technical capability, practical experience across multiple maintenance disciplines, and the ability to work safely and effectively in a tightly regulated environment.
