• Produce and review technical documentation, including calculations, drawings, reports, and risk assessments.
• Collaborate with multidisciplinary teams including nuclear safety, process, and systems engineers.
• Ensure compliance with safety cases and relevant codes through engineering oversight.
• Engage with clients, manage stakeholders, and mentor junior engineers.
• Background in mechanical engineering with strong experience in bulk solids/powder handling, preferably in regulated environments (nuclear, pharma, chemical, etc.).
• Design or evaluate mechanical systems involving containment, flow control, or automated powder transfer.
• Experience in technical documentation and engineering calculations.
• Work collaboratively to solve problems across project teams.
• Experience with glovebox or hot cell design.
• Knowledge of safety standards, ALARP, and radiological containment.
• Experience with nuclear decommissioning, new build, or fuel cycle facilities.

Qualifications:
