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 complex projects that shape communities and environments. Working here means contributing to sustainable, high-impact solutions like data centers that power the digital economy, all within a collaborative culture that values innovation and technical excellence.

About This Role

This role focuses on designing cutting-edge cooling systems for hyperscale data centers, ensuring reliability and energy efficiency. You'll be the mechanical design lead for heat rejection and HVAC, using CFD to optimize performance and collaborating across teams to integrate with critical infrastructure. Your work directly supports the backbone of cloud computing and AI.

💡 A Day in the Life

A typical day might start with a team stand-up to review project milestones, then dive into CFD simulations for a new cooling layout. Midday, you'll collaborate with electrical engineers on power distribution integration, and in the afternoon, present design options to a client, incorporating their feedback. You'll end the day updating capacity plans for future expansions.

🎯 Who AECOM Is Looking For

  • You have deep expertise in data center cooling design, including CRAHs, chilled water, DX, and containment systems, and can specify redundancy configurations (N+1, 2N) for mission-critical uptime.
  • You are proficient in CFD simulation software (e.g., Ansys Fluent, OpenFOAM) and can analyze airflow patterns to improve cooling efficiency and prevent hotspots.
  • You have experience conducting heat load calculations and capacity planning for scalable data centers, anticipating future expansion needs.
  • You thrive in fast-paced, client-facing environments, communicating technical solutions clearly to stakeholders and adapting to evolving project requirements.

📝 Tips for Applying to AECOM

1

Tailor your resume to highlight specific data center projects: list cooling system types (e.g., chilled water, DX), redundancy levels, and CFD tools used. Quantify results like PUE improvement or energy savings.

2

In your cover letter, mention your experience with heat rejection systems (cooling towers, dry coolers) and how you've ensured reliability in previous roles.

3

If you have experience with AECOM's design standards or similar large engineering firms, mention it to show cultural fit.

4

Prepare a portfolio or case study of a past data center cooling design, including CFD simulation results and energy efficiency metrics.

5

Research AECOM's recent data center projects and sustainability initiatives (e.g., net-zero commitments) to reference in your application.

✉️ What to Emphasize in Your Cover Letter

["Emphasize your hands-on experience with data center cooling system design and CFD analysis, linking it to AECOM's focus on innovative infrastructure.", 'Highlight your ability to collaborate across disciplines (electrical, mechanical) and manage client relationships in fast-paced projects.', 'Showcase your knowledge of industry standards (ASHRAE, Uptime Institute) and energy efficiency strategies (free cooling, economization).', 'Express enthusiasm for remote work and managing distributed teams, as this role is remote but may require travel to sites.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Review AECOM's recent press releases on data center projects, especially those highlighting sustainability or innovative cooling.
  • → Check AECOM's website for their approach to 'Sustainable Legacies' and how they integrate ESG into infrastructure design.
  • → Look up AECOM's tools and standards (e.g., BIM 360, Navisworks) to show familiarity in the interview.
  • → Understand AECOM's remote work culture and how they support collaboration across time zones.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Describe a time you optimized a data center cooling system using CFD. What were the results?
2 How do you approach redundancy and fault tolerance in cooling design? Give an example of a trade-off you made.
3 Explain how you would size a chilled water system for a 10 MW data center with N+1 redundancy.
4 How do you stay updated on energy efficiency trends in data centers? What recent innovation excites you?
5 Tell me about a challenging client interaction and how you managed expectations while meeting project deadlines.

⚠️ Common Mistakes to Avoid

  • Don't submit a generic resume without highlighting data center or mission-critical experience—this role is specialized.
  • Avoid downplaying the importance of CFD skills; even if you're strong in design, lack of CFD experience is a dealbreaker.
  • Don't ignore the client-facing aspect: emphasize soft skills like communication and project management, not just technical prowess.
