Role Overview: We are seeking Mechanical Engineers with a piping bias to join our client’s team, working on exciting and technically challenging projects within the nuclear and defence sectors. This role focuses on delivering robust mechanical and piping engineering solutions, ensuring designs meet project specifications, industry standards, and regulatory requirements. You will work as part of a multidisciplinary team in a highly regulated environment. This is a contract role offering a hybrid work model (minimum 2 days in the office every 2 weeks) and may fall outside the scope of IR35 (pending determination). Key Responsibilities: Develop detailed piping system engineering solutions, including layout plans, material specifications, and 3D models. Conduct and validate stress analysis, thermal expansion, and fluid flow calculations to ensure system integrity. Prepare, review, and approve mechanical and piping engineering deliverables, including technical specifications, material take-offs, and calculation reports. Ensure compliance with industry standards (e.g., ASME B31.3, BS EN 13480) and project requirements. Collaborate with multidisciplinary teams to ensure successful integration of piping systems within the overall project. Provide technical support during fabrication, installation, testing, and commissioning phases. Contribute to design substantiation and ensure systems align with safety case requirements. Participate in HAZID/HAZOP reviews and risk assessments to mitigate potential issues. Liaise with vendors and contractors for design reviews, technical submissions, and material selections. Qualifications and Experience: Demonstrated experience as a Mechanical Engineer specializing in piping within nuclear, defence, or other highly regulated industries. Proficiency in engineering tools such as AutoCAD, Plant 3D, SolidWorks, or equivalent software. Strong understanding of piping materials, welding techniques, and fabrication processes. Experience with stress analysis tools like Caesar II or similar. Knowledge of standards such as ASME B31.3, BS EN 13480, RCC-M, and relevant UK regulations. Familiarity with design documentation including method statements, QA plans, and risk assessments. Experience in design substantiation and safety case development. Degree in Mechanical Engineering or a related discipline; a Master’s degree is advantageous. Chartered Engineer status (IMechE) or actively working towards chartership. Strong problem-solving skills with the ability to deliver high-quality engineering solutions. Comprehensive knowledge of the full project lifecycle from concept design to commissioning. Why Join? This role offers an excellent opportunity to be part of high-impact projects, working in collaboration with industry leaders in the nuclear and defence sectors. With a hybrid work arrangement and potential long-term project involvement, this position provides a rewarding and flexible work environment.
