CFD Engineer

• Lead and execute CFD simulations to analyse airflow distribution, temperature profiles, and pressure differentials for internal airflow (e.g. containment design, equipment thermal performance, rack heat load analysis).
• Conduct external CFD analysis to evaluate the effects of wind loading, HVAC exhaust recirculation, generator airflow, and environmental heat transfer.
• Interpret simulation results and provide data-backed design recommendations to optimize cooling strategies (e.g., hot aisle/cold aisle containment, CRAC/CRAH placement, perforated tile layouts).
• Liaise with Lead Design Engineers, MEP consultants, and architect to integrate CFD results into facility design basis of design documents.
• Interpret simulation results and provide recommendations to optimize cooling strategies (e.g., hot aisle/cold aisle containment, CRAC/CRAH placement, perforated tile layouts).
• Develop thermal models of existing and proposed data center layouts, considering equipment loads and airflow obstructions.
• Validate CFD results with on-site measurements (e.g., IR imaging, temperature sensors, airflow meters).
• Support capacity planning by evaluating thermal impacts of IT equipment deployment or infrastructure upgrades.
• Create technical documentation, simulation reports, and presentations for internal stakeholders and external clients.
• Ensure CFD simulations are aligned with ASHRAE thermal guidelines and company performance targets.
• Stay updated with the latest CFD tools, cooling technologies, and best practices in data center thermal management.
• Collaborate with Data Analytic and BMS team in developing energy efficiency report

• Maintain compliance in accordance with all relative policies and procedures
• Support the HR department in achieving the organization developmental plan deliverables within agreed timelines.
• Meet agreed inter-departmental OLA (Operational Level Agreement).
• H&S monitoring and corrective action to meet statutory compliance, SLAs and good business practice.
• Implement company and departmental policies, processes, and work instructions as per the agreed quality and timeline/ RFS.
• Develop working methods to reduce or maintain Power Usage Effectiveness (PUE) levels.
• Task finalization and report accurately, as per agreed format, quality and within the agreed timelines
• Maintain ISO 14001 and 50001 certification, and drive action plans & reporting to achieve the objectives applicable to their respective site.
