Locations: Warrington, Newcastle and Cumbria About the Opportunity: Amentum are part of a 10-year control systems framework for designing, manufacturing, and installing control systems to aid decommissioning and operational efficiency, the project comprises of more than 200 nuclear facilities and more than 1,000 buildings in Cumbria. We are a Key supplier and are looking for people to join our team. You will be working on a multi-million-pound contract to manage system design, Programme, Test and assembly. The framework supports the site's high-hazard risk reduction programme. We have existing Teams out of Birchwood Park, Warrington, Cumbria and Newcastle North East, where we can manage hybrid working, with occasional site visits. Role Description To design, develop, implement and test PLC-based control systems, producing high-quality and comprehensive engineering design documentation such as: Requirements capture and traceability documentation (URS/RTM), System / Functional Design Specifications (SDD/FDS), Detailed Software System Specifications (SSS) Test Specifications (Module/Integration/System/Hardware), Operation & Maintenance Manuals (O&M), System Rebuild Documentation I/O, Alarm & Message Schedules, Support with project Life Time Records / Material Traceability Records In addition to the above, the role shall support the Lead Engineer and Project Manager in maintaining the planned delivery schedule, reporting technical issues, changes in scope and variations to the programmed activities where necessary. Programming PLC equipment (such as Rockwell/Schneider/Siemens)using IEC 61131 languages, producing module functions blocks and logic in accordance with the design documentation and engineering standards. Work closely with HMI/SCADA and database engineers to develop the control system architecture, producing Network Architecture Diagrams and interfacing documentation to suit, to support the visualisation of plant via an integrated Cyber Secure SCADA system. Undertake in-house acceptance testing in a formal, controlled manner of the integrated control system, ensuring change control management is maintained and recorded. Site acceptance testing (commissioning) may also be required. Support the generation of installation and commissioning documentation, operator and maintainer training and technical site support post-delivery. People are our greatest asset, and we offer a competitive package to retain and attract the best talent. In addition to the benefits you would expect, UK employees also receive free single medical cover and digital GP service, family-friendly benefits such as enhanced parental leave pay and free membership of employee assistance and parental programmes, plus reimbursement towards relevant professional development and memberships. We also give back to our communities through our programmes which incorporate matched-funding, paid volunteering time and charitable donations. Here s What You ll Need: Significant experience in the design and implementation of PLC control systems. Excellent understanding of PLC programming languages (IEC61131), PLC hardware and software, and communication protocols used in industrial (OT) control systems. Significant demonstrable experience in EC&I industry (preferably Nuclear) with PLCs. Meticulous attention to detail to ensure accuracy and reliability in PLC programming and system design. Experience in producing control system functional specifications, detailed design documents and formal Test Specifications to a high-quality level. Experience in undertaking formal and controlled testing and validation activities. Excellent fault-finding and troubleshooting skills with the ability to analyse complex systems, identify problems, and implement effective solutions. Good understanding of design drawings such as Electrical Enclosures, Control System Panels, Motor Control Centres, etc. Have a technical understanding of engineering design drawings, mainly in relation to PLC control system cubicles, enclosures, and interface panels, to assist in ascertaining constraints and design impacts from site visits, working in collaboration with the engineering teams and stakeholders to produce designs and PLC software to a high-quality level.
