The role

As a Senior Piping Engineer, you'll play a key role in the design, analysis and delivery of safety-critical piping systems supporting major nuclear projects across the UK. This is an exciting opportunity to apply your advanced mechanical and piping engineering expertise within a highly regulated environment while broadening your nuclear industry experience through structured development and re-skilling opportunities.

• Reviewing engineering drawings, piping layouts and 3D models to ensure compliance with technical and industry standards.
• Leading technical interfaces with suppliers, contractors and multidisciplinary engineering teams.
• Producing and reviewing engineering specifications, calculations, reports and design documentation.
• Supporting project delivery through technical problem solving, stakeholder engagement, site visits and quality assurance activities.

This is a full-time, permanent position based at our Grimsby or Hessle offices, with hybrid working available and an expectation of three days per week on site.

Essential experience of the Senior Piping Engineer:

• Proven experience in piping stress analysis and pressure systems engineering within highly regulated industries such as power generation, oil and gas, petrochemical, energy, process, defence or nuclear.
• Strong knowledge of piping codes and standards including ASME B31.1, ASME B31.3 and BS EN 13480.
• Hands-on experience using Caesar II for pipe stress analysis and PV Elite for pressure vessel assessment.
• Experience reviewing and approving engineering calculations, specifications, piping isometrics and vendor documentation.
• Experience managing technical interfaces with suppliers, subcontractors and multidisciplinary engineering teams.
