Description

The day‑to‑day responsibilities include overseeing HVAC, electrical and plumbing systems specific to data‑center operations, implementing environment protocols and Method‑of‑Procedure processes, and conducting regular performance analyses of mechanical and electrical infrastructure.

You will apply mechanical engineering principles to improve efficiency and reliability, design cooling solutions for high‑density server environments, enhance airflow management, and develop preventive‑maintenance schedules for all critical infrastructure.

The position also requires leading root‑cause analyses for system failures, implementing corrective actions and upgrades, proposing energy‑saving initiatives to reduce PUE, and evaluating green technologies while ensuring compliance with standards such as ASHRAE and ISO.

• Oversee HVAC, electrical, and plumbing systems in data‑center operations.
• Implement and maintain environment protocols and Method‑of‑Procedure (MOP) processes.
• Perform regular performance analyses of mechanical and electrical infrastructure.
• Design and optimize cooling solutions for high‑density server loads.
• Enhance airflow management strategies to improve efficiency.
• Create and execute preventive‑maintenance schedules for critical equipment.
• Lead root‑cause investigations and apply corrective actions for system failures.
• Propose energy‑saving initiatives to lower Power Usage Effectiveness (PUE).
• Evaluate and integrate green technologies while complying with ASHRAE, ISO, and local regulations.
• Conduct safety audits and enforce safety protocols.
• Mentor facility technicians and engineers to develop technical skills.
• Manage complex infrastructure projects, including expansions and upgrades.
• Coordinate with vendors and service providers to ensure optimal system performance.
• Communicate infrastructure status and improvement plans to executive management.
• Maintain EPA 608 certification and CRAC (Liebert) maintenance expertise.

Requirements

We are seeking a Data Center Mechanical Engineer (SME) with extensive mechanical engineering experience and at least five years of data‑center operations expertise.
