  * 

    Ensure mechanical designs comply with nuclear site processes, UK regulations, and relevant industry standards (BS, EN, ISO).

  * 

    Undertake engineering calculations to justify structural integrity, lifting capacity, pressure boundaries, and mechanical performance.

  * 

    Provide technical leadership to designers, graduates, and junior engineers.

  * 

    Work closely with CE&I, process, civil, and safety teams to produce integrated, safe design packages.

  * 

    Support hazard studies including HAZOPs, risk assessments, and ALARP evaluations.

  * 

    Produce mechanical equipment specifications, data sheets, and technical procurement documents.

  * 

    Review vendor drawings, calculations, and compliance statements.

  * 

    Conduct site surveys and walkdowns to verify existing plant conditions and support design development.

  * 

    Provide engineering support during installation, testing, and commissioning activities.

  * 

    Ensure all work follows strict configuration control and quality assurance processes.

  * 

    Contribute to safety case information where mechanical engineering input is required.

  * 

    Ensure designs consider operability, maintainability, reliability, and lifecycle requirements.

  * 

    Manage and resolve technical queries from the supply chain, fabricators, and site teams.

  * 

    Support project planning, estimates, and engineering work-scope development.

  * 

    Identify design risks and drive safe, compliant engineering solutions.

  * 

    Promote strong nuclear safety culture and adherence to engineering best practice.

Essential Skills & Experience

  * 

    Proven experience as a mechanical engineer in nuclear or other highly regulated industries.

  * 

    Strong capability in mechanical design, engineering substantiation, and technical leadership.

  * 

    Competence with relevant design tools (e.g., AutoCAD, Inventor, SolidWorks).

  * 

    Strong understanding of lifting operations, mechanical handling, remote tooling, and engineered safety systems.

  * 

    Ability to review and approve mechanical deliverables to a high standard.

  * 

    Effective communicator able to work collaboratively in multi-discipline teams.

Desirable Experience

  * 

    Experience on decommissioning, waste retrieval, or legacy facility remediation projects.

  * 

    Familiarity with Sellafield or Magnox engineering processes and drawing standards.
