Job Description

You will design, optimize, and scale cooling technology infrastructure to ensure system reliability, sustainability, and efficiency for high-density AI and cloud compute workloads, driving cost targets and speed-to-market objectives.

Responsibilities

Design system topology and detailed schematics from heat rejection plant to rack-level cooling for air-cooling and liquid cooling applications
Develop cooling solutions aligned with control philosophy to ensure continuous operation of diverse cooling technologies
Plan capacity with thermal buffer or fast response to accommodate dynamic power demands from AI workloads
Select and rightsize cooling technology equipment to meet peak demand while ensuring modularity and scalability
Configure and sequence operations to optimize Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE)
Perform computational fluid dynamics and hydraulic calculations to comply with environmental standards and heat transfer fluid service level agreements
Standardize build-to-suit design templates to shorten design cycles and achieve cost targets
Future-proof cooling technology designs to adapt to evolving workload demands
Manage concurrent and fast-track projects, applying innovative design solutions and driving outcomes with internal and external partners

Required competencies and certifications

Proven design experience across regional metropolitan areas
Mechanical Professional Engineer (ACMV) with practicing certificate preferred
Minimum 15 years in Data Centre Detail Design, including over 5 years in principal engineer or MEP manager roles
Expertise in mechanical studies including air flow modeling, heat load calculation, hydraulic calculation, computational fluid dynamic modeling for hot air re-entrainment, temperature rise simulation, boundary noise simulation, and wind influence on hot air exhaust
Experience designing and selecting equipment for make-up water tanks, thermal storage tanks, centralized diesel storage and delivery systems, goods lifts, and fireman lifts
Familiarity with cooling methods such as direct and indirect evaporative cooling, closed circuit heat exchange, dry coolers, magnetic bearing chillers, cold plate liquid cooling, and immersion cooling
Experience with chiller plant operation systems, sequence of operation, and PLC flow chart development
Experience in energy modeling for Green Mark Data Centres
Experience working in hyperscale data centers
Proficiency in AutoCAD for design and drafting
Willingness to travel based on project requirements

Preferred competencies and qualifications

LEED professional credentials
