Mechanical/HVAC Engineer – Data Center Infrastructure Engineering (DCIE), Data Center Infrastructure Engineering

The Mechanical/HVAC Engineer within Data Center Infrastructure Engineering (DCIE) is responsible for the design implementation and optimization of HVAC and airflow management systems across Amazon Fulfillment Centers (FCs) worldwide. This role ensures efficient cooling thermal management and environmental controls for missioncritical IT infrastructure including MDFs IDFs UPS rooms and structured cabling spaces.

Mechanical Engineers collaborate closely with DCIE Engineers (electrical telecom and general) TPMs and DCIO Engineers to drive resiliency sustainability and energy efficiency in Amazons IT infrastructure. They play a key role in reducing cooling costs optimizing airflow containment and improving HVAC reliability to support Amazons expanding fulfillment network.


Key job responsibilities
HVAC Design & Engineering

Design evaluate and maintain HVAC systems for MDFs IDFs and IT spaces in fulfillment centers.
Develop and maintain design standards specifications and BOMs for cooling infrastructure ensuring global consistency.
Conduct thermal load analysis to determine cooling requirements for IT infrastructure deployments.
Implement containment solutions (hot/cold aisle inrow cooling rackbased cooling etc.) to improve airflow efficiency.
Evaluate and recommend highefficiency HVAC equipment to reduce power consumption and operating costs.

Implementation & Lifecycle Management

Provide technical support for HVAC installation commissioning and troubleshooting.
Assist in HVAC lifecycle planning identifying aging systems for proactive replacement.
Partner with TPMs and DCIO Engineers to execute HVAC remediation projects ensuring compliance with Amazons performance standards.
Collaborate with site operations teams to validate cooling system performance and identify optimization opportunities.

Cooling Optimization & Energy Efficiency

Deploy realtime HVAC monitoring and analytics to improve cooling performance and reduce inefficiencies.
Work with SDEs and DCIM teams to integrate temperature humidity and airflow monitoring into dashboards.
Optimize chiller CRAC/CRAH and economizer operations to improve power usage effectiveness (PUE).
Support Amazons Climate Sustainability Initiatives identifying opportunities for renewable energy integration and HVAC decarbonization.

Operational Support & Incident Response

Serve as an SME for HVAC systems supporting DCIO Engineers in troubleshooting cooling failures airflow imbalances and humidity control issues.
Participate in incident response for Sev1/Sev2 HVACrelated outages driving root cause analysis and corrective actions.
Conduct postincident reviews ensuring lessons learned are integrated into future designs and processes.

Compliance & Risk Management

Ensure HVAC systems comply with ASHRAE ANSI and regional HVAC regulations.
Work with deployment teams to review sitespecific HVAC design compliance and address deviations.
Maintain air quality humidity control and airflow standards for IT environments.



A day in the life
As a Mechanical/HVAC Engineer in DCIE your day begins by reviewing HVAC performance dashboards and overnight alerts to identify sites with airflow imbalances cooling inefficiencies or humidity deviations. You may start with a deep dive into thermal load calculations for a new FC build or collaborate with DCIO Engineers to troubleshoot an active cooling incident in an MDF room. Midday youre evaluating sitespecific HVAC designs or reviewing CFD models to validate containment strategies and airflow optimization. Youll meet with TPMs to align on lifecycle projects ensuring aging CRAC units or economizers are targeted for replacement. In the afternoon you work with SDEs and DCIM teams to enhance temperature and humidity telemetry or assess opportunities to integrate highefficiency HVAC systems into Amazons Climate Sustainability Initiatives. Every day balances urgent incident response with longterm design improvementssupporting the resiliency standardization and sustainability of Amazons global IT infrastructure.
