Principal Data Center Mechanical Engineer

Principal Mechanical Engineer

As Principal Mechanical Engineer you will own the Datacenter cooling system design along with thermal and fluid-handling designs that keep tens of thousands of GPUs cool and reliable. Your mission is to deliver reference-grade HVAC, liquid-cooling and containment solutions that scale rapidly, minimise PUE and fit into diverse global sites.

Focus

• Manage all aspects of the mechanical engineering system for datacenters including air cooling, liquid cooling and infrastructure coordinating with all other discipline requirements.
• Create strategy for datacenter mechanical system design and deployment.
• Develop mechanical design standards for high-density air, rear-door heat-exchanger, cold-plate and immersion-cooling systems.
• Lead innovation for mechanical engineering systems for achieving high efficiency, better PUE and WUE.
• Develop and maintain the basis of design, master specification and master drawings.
• Facilitate developing project specific drawings and documentation based on the master design with local adaptation working with external design consultants.
• Develop and maintain a master sequence of operation and control strategy for the datacenters.
• Support and perform factory inspections, site quality inspections, testing and commissioning of mechanical systems.
• Conduct CFD modelling and capacity planning to validate airflow, pressure and temperature targets.
• Specify chillers, dry coolers, pumps, CRAH / CRAC units and redundant pipework topologies.
• Drive energy-efficiency initiatives; free-cooling, water-side economisers, waste-heat re-use.
• Produce mechanical bill-of-materials, sequence-of-operations and commissioning scripts.
• Interface with Electrical, Controls and Construction teams through 30 / 60 / 90% design reviews.
• Willing and able to travel domestic and international to support projects. 20% travel is expected for this role.
