      Lead Process Engineering on a Major Nuclear Programme
      Are you an experienced Principal Process Engineer looking for your next long-term contract within the nuclear sector?
      This is an excellent opportunity to join a major nuclear engineering programme in Warrington, taking a lead role within a small team of process engineers and helping deliver technically challenging work in a highly regulated, safety-critical environment.
      You will play a key role in the development of the G3 Phase 3 project, supporting the project through concept development and into preliminary and detailed design.

      The Opportunity
      The project involves the movement and storage of nuclear fuel following Post-Irradiation Examination (PIE), including the transfer of fuel in PIE cans inside transport flasks via an intermediate storage pond before onward transfer to long-term storage.
      As Principal Process Engineer, you will provide technical leadership to the process engineering team, working closely with a wide range of engineering and project disciplines.
      Your responsibilities will include:

      • Leading a small team of Process Engineers and managing workloads, resources and delegation.
      • Delivering process engineering design in line with project schedules and requirements.
      • Supporting the Responsible Process Engineer and Engineering Manager with team building, estimates and programme planning.
      • Developing and assessing concept, preliminary and detailed design.
      • Producing and reviewing key process engineering deliverables, including Basis of Process Safety, hydrogen hazard management strategies, DSEAR assessments, sequence and interlock definition documentation and process calculations.
      • Assessing hazards associated with fuel storage in ponds and transport flasks/sealed containers, including corrosion, hydrogen generation, heat generation and liquor carryover.
      • Supporting nuclear safety case development and providing appropriate nuclear substantiation.
      • Working collaboratively with Project Management, Safety Assessors, Plant Engineering, Operations, Commissioning and other design disciplines.
      • Presenting process designs at assurance reviews, technical committees and management safety committees.

      What We’re Looking For
      We’re looking for an experienced senior/principal-level Process Engineer with strong leadership capability and experience delivering process engineering designs within complex projects.
      Essential:

      • Masters Degree in Chemical Engineering or equivalent.
      • Chartered Engineer (CEng) with IChemE.
      • Proven experience managing teams of Process Engineers.
      • Experience managing workloads, resource profiling and delegation.
      • Strong communication and report-writing skills.
      • Experience supporting nuclear safety case development and nuclear substantiation.
      • Understanding of hydrogen generation through radiolysis and associated hazard management.
      • Experience with safety assessment techniques such as HAZOP.
      • Ability to work effectively within time and cost constraints.

      Desirable:

      • Previous experience working to Sellafield Ltd processes and procedures.
      • Experience undertaking DSEAR assessments.
      • Knowledge of nuclear material transfers, transport flasks and nuclear storage ponds.

      Why Apply?
      This is a chance to take a genuine technical leadership role on a high-profile nuclear programme, working alongside experienced multidisciplinary engineering teams and contributing to the development of safety-critical nuclear infrastructure.
      With a 12-month+ contract, £61 per hour Inside IR35 and hybrid working, this represents a strong opportunity for an experienced Principal Process Engineer seeking a long-term assignment in the Warrington nuclear engineering market.
      If you’re a Chartered Process/Chemical Engineer with nuclear experience and strong team leadership skills, we’d like to hear from you.
