Mechanical Subject Matter Expert, Data Center Environmental Systems

Responsibilities

• Serve as the primary technical authority on data center mechanical systems, with a focus on environmental controls, water treatment, and cooling infrastructure including chillers, cooling towers, and fluid distribution systems
• Develop and maintain standards, specifications, and best practices for water and environmental mechanical systems across the global data center portfolio
• Conduct root cause analysis and failure mode investigations for mechanical and environmental system incidents, driving corrective and preventive action plans
• Evaluate and recommend improvements to water usage effectiveness metrics, including optimization of cooling tower chemistry, blowdown cycles, and recirculating water systems
• Collaborate with design and construction teams to review mechanical engineering drawings, specifications, and commissioning plans for new data center builds and retrofits
• Partner with environmental health and safety teams to ensure mechanical systems meet regulatory requirements for water discharge, chemical handling, and environmental compliance
• Provide technical guidance to operations engineers and technicians on maintenance procedures, system troubleshooting, and equipment lifecycle management
• Lead cross-functional working groups to evaluate emerging cooling technologies and water conservation strategies applicable to hyperscale data center environments
• Develop and deliver technical training programs on environmental and water mechanical systems for operations and engineering personnel
• Support capacity planning and risk assessments for mechanical infrastructure, identifying vulnerabilities and recommending mitigation strategies

Requirements

• Experience collaborating with design, construction, and regulatory compliance teams on mechanical infrastructure projects
• 6+ years of experience with cooling infrastructure systems including chillers, cooling towers, heat exchangers, and associated water treatment and chemical dosing systems
• Experience conducting root cause analysis and driving corrective action for mechanical system failures in operational environments
• 6+ years of experience in mechanical engineering or operations with a focus on data center or large-scale industrial environmental and water systems
• Experience developing technical standards, specifications, or engineering guidelines for mechanical or environmental systems in mission-critical facilities

Qualifications

• Familiarity with ASHRAE data center thermal guidelines, cooling system commissioning standards, and environmental regulatory frameworks governing water discharge and chemical use
• Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
• Experience with water usage effectiveness optimization strategies and sustainability programs in hyperscale data center environments
• Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
• Experience evaluating and deploying alternative cooling technologies such as direct liquid cooling, adiabatic cooling, or closed-loop water-free systems
• Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
