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 cutting-edge data center designs that power the digital world, with a strong emphasis on environmental stewardship and technical excellence.

About This Role

As a Senior Mechanical Designer for Data Centers, you'll lead the design of heat rejection and HVAC systems that ensure optimal performance and reliability for mission-critical facilities. Your work directly impacts energy efficiency and uptime, making you a key player in the backbone of modern connectivity.

💡 A Day in the Life

A typical day might start with reviewing CFD simulation results from overnight runs, then collaborating with the electrical team on a new project's cooling layout. You could spend the afternoon refining a heat rejection system design using Revit or AutoCAD, followed by a virtual meeting with the client to discuss efficiency targets and PUE goals.

🎯 Who AECOM Is Looking For

  • A seasoned mechanical engineer with 8+ years of experience specifically in data center or mission-critical facility design, demonstrating a deep understanding of redundancy and reliability requirements.
  • Expert in HVAC system design (CRAH, chilled water, DX, containment) and proficient with CFD analysis tools (e.g., Ansys Fluent, 6SigmaDC) to optimize airflow and cooling.
  • Skilled in heat load calculations and familiarity with industry standards like ASHRAE, Uptime Institute, and TIA-942.
  • A collaborative team player who can effectively coordinate with electrical, structural, and controls engineers to integrate HVAC with critical infrastructure.

📝 Tips for Applying to AECOM

1

Tailor your resume to highlight specific data center projects, including cooling system types (e.g., chilled water, DX) and your role in CFD analysis and heat load calculations.

2

Include metrics: e.g., 'Designed HVAC system for a 10MW data center achieving PUE <1.4' or 'Reduced cooling energy by 15% via CFD optimization.'

3

Highlight any experience with remote collaboration tools and distributed teams, as this role is fully remote within the U.S.

4

Mention familiarity with AECOM's sustainability goals in your cover letter, linking your designs to energy efficiency and reduced carbon footprint.

5

Prepare a portfolio of past project summaries or case studies that demonstrate your ability to solve complex cooling challenges in data centers.

✉️ What to Emphasize in Your Cover Letter

['Emphasize your hands-on experience with data center cooling technologies and CFD analysis, citing specific projects and outcomes.', "Connect your design philosophy to AECOM's mission of building sustainable legacies, highlighting how your work improves energy efficiency and reliability.", 'Showcase your ability to collaborate across disciplines, especially with electrical teams, to ensure seamless integration of HVAC with power systems.', 'Express enthusiasm for the remote work model and your self-discipline in managing projects independently while staying connected with global teams.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Explore AECOM's recent data center projects and case studies on their website to understand their design approach and client base.
  • → Read about AECOM's sustainability initiatives and how they measure environmental impact in infrastructure projects.
  • → Familiarize yourself with AECOM's remote work culture and any tools they use for collaboration (e.g., Teams, BIM 360).
  • → Research industry trends like liquid cooling and modular data centers to discuss how you can bring innovation to the role.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk me through a data center project where you designed the HVAC system. How did you determine redundancy levels and cooling capacity?
2 Describe a time you used CFD analysis to solve an airflow or cooling issue. What tools did you use and what was the outcome?
3 How do you stay updated on the latest data center cooling technologies (e.g., liquid cooling, free cooling) and apply them to designs?
4 Explain your approach to collaborating with electrical engineers when integrating HVAC with power distribution and backup systems.
5 AECOM is committed to sustainability. How have you incorporated energy efficiency or green design principles into your previous data center projects?
