About This Role
As a Senior Mechanical Engineer on the Data Center and Mission Critical team, you will lead the design of heat rejection and HVAC systems for data centers, ensuring they meet the demanding requirements of scale, speed, and consistency. This remote role involves hands-on, client-facing work with global clients and offers upward career mobility within a world-class consulting firm. You'll be instrumental in shaping the mechanical infrastructure that keeps the digital world running.
💡 A Day in the Life
Your day might start with a virtual design review with a global client, followed by coordinating with a remote team on heat rejection calculations for a new data center. Later, you could be reviewing vendor submittals, mentoring junior engineers, or preparing for an upcoming onsite visit. The pace is fast, and you'll juggle multiple projects while ensuring every design meets AECOM's high standards for sustainability and performance.
🚀 Application Tools
🎯 Who AECOM Is Looking For
- Bachelor's degree in Mechanical Engineering and PE license, with 8+ years of experience in mission critical or data center HVAC design.

💬 Prepare for These Interview Topics
Based on this role, you may be asked about:
⚠️ Common Mistakes to Avoid
- Submitting a generic mechanical engineering resume without highlighting data center or mission critical experience—this role requires specialized knowledge.
- Underestimating the importance of remote work skills; failing to demonstrate ability to self-manage and collaborate effectively across distances can be a dealbreaker.
- Ignoring the client-facing aspect; candidates who focus solely on technical skills without showing comfort in client interactions may not fit the role.
