• Lead the design and engineering of nuclear and safety-significant ventilation systems, including HVAC, air handling units, filtration, ductwork and associated mechanical plant.
• Develop and review technical specifications, calculations, equipment schedules and design documentation through concept, preliminary and detailed design phases.
• Work closely with multidisciplinary teams across building, architectural, structural, electrical, controls, process and operations to integrate ventilation systems into the wider facility design.
• Undertake engineering studies, airflow modelling, contamination control assessments, hazard and risk assessments to support design development and technical decision-making.
• Support safety cases, engineering justifications, requirements management and verification and validation activities for safety-significant ventilation and containment systems.
• Provide technical leadership and mentorship to engineers and designers, while managing scope, programme, resources and technical deliverables.
• Support commissioning, testing, balancing, containment verification and performance acceptance activities, as well as engagement with clients, stakeholders, suppliers and regulators.
