Responsibilities

• Author, develop and assess Design Substantiation Documents for major civil and structural assets.
• Manage design changes, concessions and supporting documentation through due process.
• Produce and maintain Examination, Inspection, Maintenance & Testing (EIMT) schedules and associated documentation.
• Review technical reports, safety submissions and provide expert civil/structural input to multidisciplinary teams.
• Present design substantiations to internal review panels and technical assurance groups.
• Develop robust technical justifications for structural design modifications in high‑hazard environments.
• Collaborate with mechanical, electrical and building services engineers to deliver integrated solutions.

• Minimum 5 years' experience in the design and assessment of reinforced concrete and steel structures.
• Proven experience producing robust technical justifications for design modifications.
• Incorporated Engineer status (or equivalent experience).
• Experience contributing to multidisciplinary engineering projects.
• Additional qualifications that are welcomed: Chartered Engineer status, experience in marine, defence, nuclear or other high‑hazard industries, familiarity with safety case development techniques such as HAZID/HAZOP, knowledge of relevant design codes and standards for safety‑critical structures.

Position Setting

This full‑time position (40 hours per week) is based on a secure site within a technically advanced infrastructure environment. You will be working within an embedded engineering team providing design assurance, safety justification and technical support to ongoing operations and future development programmes.
