How to Apply for Senior Mechanical Designer, Data Centers - Remote (U.S.)

at AECOM

🏢 About AECOM

AECOM is a global leader in infrastructure consulting, known for delivering sustainable and innovative solutions for complex projects. Working here means contributing to building the future of data centers, with a strong emphasis on environmental stewardship and cutting-edge design.

About This Role

This role focuses on designing heat rejection and HVAC systems for data centers, ensuring optimal cooling, redundancy, and energy efficiency. As a Senior Mechanical Designer, you'll leverage CFD analysis and heat load calculations to optimize airflow and collaborate across teams to integrate critical infrastructure, directly impacting the reliability and sustainability of data center operations.

💡 A Day in the Life

You'll start by reviewing project specs and collaborating with electrical engineers on integration points. Mid-morning, you might run CFD simulations to optimize airflow, then join a client call to discuss cooling capacity plans. Afternoons are spent refining designs in CAD, performing heat load calculations, and coordinating with vendors on equipment specifications.
