This role is full time, 35 hours per week and provides hybrid working arrangements with a minimum of 2 days in the office/onsite.

Requirements

  • Strong background in safety engineering within complex projects and high‑hazard industries (minimum Senior Safety Engineer level).
  • Experience reviewing or managing safety cases and assessing design intent.
  • Dockyard, defence, or nuclear industry experience (oil and gas, rail, aerospace also considered).
