Key Responsibilities The Principal Mechanical Engineer will act as a technical lead and subject matter expert for mission-critical Data Center projects, responsible for end-to-end HVAC design, engineering, coordination, and commissioning support. This role goes beyond design and requires complete lifecycle ownership, from concept definition and cooling strategy to detailed design, construction support, commissioning, and performance validation. You will be responsible for advising on AI deployment options and examining potential impact on the design by leading cross-discipline conversations. Therefore, it’s required to possess experience and working knowledge at least on electrical principles, structural, architectural, DC operations & maintenance requirements, installation and commissioning procedures.
