Assistant Chief Engineer - Mechanical Team Lead

About the Role

Day‑to‑day responsibilities include overseeing HVAC, electrical, and plumbing systems specific to data‑center operations, implementing and maintaining critical environment protocols and Method of Procedure (MOP) processes, and conducting regular performance analyses of facility mechanical and electrical systems. You will also monitor system performance and ensure continuous reliability. Mechanical engineering tasks involve applying engineering principles to improve data‑center efficiency and reliability, designing cooling solutions for high‑density server environments, and enhancing airflow management strategies. You will develop comprehensive preventive‑maintenance schedules, lead root‑cause analysis for system failures, and implement corrective actions and system upgrades. The engineer will propose and execute energy‑saving initiatives to reduce Power Usage Effectiveness (PUE), evaluate and integrate green technologies, and ensure adherence to industry standards such as ASHRAE and ISO as well as local regulations. Safety protocols will be overseen, regular safety audits conducted, and a team of facility technicians and engineers mentored. You will manage complex data‑center infrastructure projects, including expansions and upgrades, collaborate with equipment vendors and service providers, and communicate infrastructure status and improvement plans to executive management. Project leadership will ensure optimal system performance and alignment with business goals. • Oversee HVAC, electrical, and plumbing systems in data‑center operations • Implement and maintain environment protocols and Method of Procedure (MOP) processes • Conduct regular performance analyses of mechanical and electrical systems • Design and deploy cooling solutions for high‑density server environments • Optimize airflow management strategies • Develop and execute preventive‑maintenance schedules for critical infrastructure • Lead root‑cause analysis and implement corrective actions for system failures • Propose energy‑saving initiatives to reduce Power Usage Effectiveness (PUE) • Evaluate and integrate green technologies compliant with ASHRAE, ISO, and local codes • Conduct safety audits and enforce safety protocols • Mentor and guide facility technicians and engineers • Manage data‑center infrastructure projects, expansions, and upgrades • Collaborate with vendors and service providers to ensure optimal performance • Communicate infrastructure status and improvement plans to executive management
