We are looking for a Mechanical Engineer specializing in air handling systems, cooling infrastructure, and PLC programming for data center environments. In this role, you will design, develop, and optimize HVAC systems, liquid cooling loops, and other thermal management infrastructure to efficiently manage IT heat loads. You will also collaborate closely with manufacturing, construction, and operations teams to ensure the final product is efficient, reliable, and optimized for high-performance data center operations.

Responsibilities:

• Design, develop, and optimize air handling and cooling systems for data centers, including HVAC components (rooftop exhaust fans on VFDs,) liquid cooling systems (chillers, CDUs, dry coolers), hot/cold water loops.
• Program, configure, and optimize Schneider PLCs (EcoStruxure, Modicon) and other platforms to manage and automate cooling infrastructure, ensuring consistent and efficient heat load management.
• Create detailed engineering designs and layouts for complex cooling systems, including piping, ducting, and equipment layout using CAD software (SolidWorks, AutoCAD).
• Perform thermal analysis, system simulations, and CFD modeling to validate cooling system designs, ensuring they can handle dynamic IT heat loads while optimizing power usage effectiveness (PUE).
• Work closely with multidisciplinary teams, including electrical engineers, software developers, construction personnel, and operations staff, to ensure seamless integration of mechanical and electrical systems.
• Provide on-site support for the commissioning, start-up, and troubleshooting of fans, VFDs, PLCs, sensors, chillers, CDUs, and other cooling systems.
• Develop and maintain preventive maintenance plans for the cooling and air-handling systems to maximize uptime in mission-critical environments.
• Conduct performance testing to ensure HVAC and liquid cooling systems meet design specifications and performance targets.
• Collaborate with the operations team to develop and execute plans for minimizing downtime during system upgrades and maintenance activities.
• Prepare and maintain technical documentation, manuals, and training resources for system operators, maintenance personnel, and technical staff.
• Manage projects from initial concept through design, manufacturing, testing, and commissioning, ensuring timelines and budgets are met.

Desired Skills, Qualifications and Competencies include:

• Minimum Bachelor’s degree in Mechanical Engineering or a related field. Master’s degree &/or Professional Engineering (PE) certification is highly regarded.
• 0-5 years of experience in designing HVAC and cooling systems for mission-critical environments, such as data centers.
• Proficiency with Schneider PLCs (EcoStruxure, Modicon) and other platforms (e.g., Siemens, Allen-Bradley).
• Hands-on experience with liquid cooling systems (chillers, CDUs, dry coolers) and the management of hot/cold water loops in industrial or data center environments preferred.
• Knowledge of HVAC systems, ASHRAE standards, and cooling infrastructure tailored for IT heat load management.
• Familiarity with Building Management Systems (BMS), SCADA, and integrating mechanical systems with data center operations.
• Strong analytical and problem-solving skills, with experience in thermodynamic analysis, and fluid dynamics in data center or industrial settings preferred.
• Experience with CFD simulations and thermal management of large-scale facilities is highly desirable.
• Experience working with multi-disciplinary teams in construction/operations settings is desirable.
