• Heating, cooling, and ventilation (including active ventilation)
• Above-ground drainage (including active effluent)
• Controls and instrumentation
• Low-voltage electrical distribution
• Communications and data systems
• Fire detection and alarm systems
• Industrial and emergency lighting
• Site broadcast (PA) systems
• Experience in substantiating Safety Integrity Level (SIL - BS61582-1), ONR, and high-integrity systems for nuclear safety functions.
• Familiarity with engineering design and safety practices, and internal procedures for health & safety, design, and quality assurance.

QUALIFICATIONS

• Degree in a relevant engineering discipline (or equivalent qualification).
• Chartered Engineer status
• Completion of a Nuclear Introductory Course or equivalent experience in nuclear/marine systems.

KEY RESPONSIBILITIES

• Lead and contribute to the design and substantiation of Safety Instrumented Systems (SIS) and high-integrity control systems.
