Production Technician (C&I) in Leiston

Do you enjoy solving complex technical problems, keeping critical systems running safely and knowing your work really matters? This is a hands‑on Control and Instrumentation maintenance role where your expertise helps protect people, plant and the wider environment every single day. You will join a highly skilled, supportive maintenance team within a tightly regulated nuclear environment. Safety comes first, standards are high, and teamwork is essential. In return, you will work predictable daytime hours over a four‑day week, Monday to Thursday, giving you long weekends and strong work‑life balance while contributing to a nationally important mission.

What Will You Be Doing

• You will maintain, fault‑find and improve control and instrumentation systems across the site, ensuring plant reliability, compliance and safe operation.
• Your work will cover both preventative and corrective maintenance, with a strong focus on quality, documentation and engineering judgement.
• You will work independently when needed, while also supporting colleagues and sharing knowledge within the team.
• Your key focus will include:

• Maintaining, calibrating and repairing process instrumentation such as pressure, flow, temperature and level systems, including PLC control and alarms.
• Investigating plant faults, identifying root causes and proposing robust, practical engineering solutions, supported by clear written reporting.
• Working strictly to health, safety, environmental, quality and site licence requirements, following work instructions, procedures and best practice at all times.
• Supporting site objectives across Sizewell A and Bradwell, including communication of findings, meeting maintenance plans and contributing to emergency arrangements when required.

Who Are We Looking For

• You are a Control and Instrumentation maintenance professional who takes pride in working to a high standard and doing the right thing, even when no one is watching.
• You are comfortable working in a highly regulated environment, understand the importance of compliance and documentation, and can apply logical fault finding under pressure.
• You communicate clearly, support team learning and remain customer focussed in your work.
• You will need a recognised technical qualification at Level 3, such as City and Guilds or BTEC ONC, along with proven hands‑on experience in Control and Instrumentation maintenance.
• You should be confident reading and interpreting engineering drawings, carrying out fault diagnosis and working with modern maintenance techniques.
• Experience in the nuclear industry is welcomed but not essential – what matters most is your safety mindset, technical capability and ability to work effectively on your own or as part of a performing team.
