• Develop and review mechanical systems incorporating chillers, cooling towers, air handling units (AHUs), heat pumps, generators and associated fuel oil infrastructure.
• Establish technical design requirements, coordinate mechanical interfaces with electrical, plumbing and fire protection teams, and ensure integrated project delivery.
• Oversee design documentation, technical reviews and project deliverables, providing guidance to engineers and maintaining consistent engineering standards.
• Support commissioning activities, including coordination with internal and external commissioning teams, system testing, process water flushing and treatment.
• Work with energy modelling specialists to improve system efficiency and reduce carbon impact while maintaining the resilience required for 24/7 data-center operations.
• Build relationships with clients and project stakeholders, contribute to business development activities and represent the business at relevant industry events.

Preferred Qualifications

• Bachelor's degree in Mechanical Engineering or a closely related discipline.
• 8-10+ years of mechanical engineering design experience within an engineering consultancy or comparable design environment.
• Demonstrable experience designing mechanical/HVAC systems for mission-critical facilities, ideally large-scale data centers.
• Strong technical knowledge of data-center cooling infrastructure, including chillers, cooling towers, AHUs, heat pumps and associated mechanical plant.
• Experience with standby generation systems and associated fuel oil infrastructure.
• Proficiency in Revit or AutoCAD
• Understanding of building controls systems, energy modelling and applicable industry standards, including ASHRAE 90.1, 90.4 and TC 9.9.
• Experience supporting construction, commissioning and project delivery, with the ability to lead technical teams and manage client relationships.
