• Participating in client meetings, workshops, technical reviews and presentations
• Managing defined work packages with a focus on quality, schedule, cost and client outcomes

Essential experience

• Royal Navy Submarine Service background in a nuclear propulsion / marine engineering environment
• Qualified Category B Nuclear Watchkeeper, with practical watchkeeping experience on a nuclear submarine
• Strong understanding of nuclear professionalism, procedural compliance, conservative decision-making and safety culture
• Ability to translate operational experience into clear, defensible technical advice
• Confident communicator (written and verbal) with multi-disciplinary teams and senior stakeholders
• UK National and able to meet Security Check (SC) clearance requirements
• Clear understanding of ongoing obligations around classified / sensitive information

Package

• £55,000-£85,000 (DOE)

• Pension matched up to 10%
• Private healthcare
• Professional development support + pathway to civilian accreditation/registration
• Performance-related bonus
