The ideal candidate for this position should be familiar with the tech sector, mission critical and data center industry, understanding the requirements of scale, speed, and consistency in data centers.
This position offers the flexibility of a remote work schedule and can be based from a variety of locations in the US where AECOM has an office.
Although the position is primarily remote periodic travel may be required for client meetings, key project milestones, onsite collaboration sessions, or other business‑critical activities. Travel is expected to be occasional and scheduled in advance.
AECOM is a leader in the global data center consulting industry with robust teams in the Americas, Europe, Africa, Asia, and Australia. In this role, you will have the opportunity to work with our teams around the world on high-profile, fast-paced data center projects for global clients. This is a hands-on, client-facing role with an opportunity for upward career mobility.
Responsibilities:
- Data Center Heat Rejection and HVAC System Design: Developing and designing Heat Rejection and HVAC systems specifically tailored for data centers, considering factors such as type of cooling requirement as air cooled or direct fluid cooled, associated cooling loads, future flexibility of the system to accommodate variable heat distribution scenarios, phased construction and operation, airflow management, humidity control, system redundancy providing concurrent maintainability, energy efficiency, and compliance with industry standards and best practices.
- Cooling System Selection: Selecting appropriate air/water side cooling systems for data centers, including Fan wall units, computer room air handlers (CRAHs), chilled water systems, DX systems and CRAC units, in-row cooling, and containment solutions, based on the specific cooling requirements of the data center and the criticality of the equipment.
- Computational Fluid Dynamics (CFD) Analysis: Conducting internal CFD simulations to optimize airflow distribution, transient period analysis, identify hotspots, and ensure efficient cooling throughout the data center. Conducting external CFD on individual buildings and/or campus-wide to simulate effects of different electrical and mechanical components on each other and effects on design day selection criteria capacity of each component. For both types, prepare and/or direct preparation of models and analyse the results to recommend design modifications and optimize the Heat rejection and HVAC system performance. Coordinate the required changes and resulting effects with other trades on project.
- Redundancy and Fault Tolerance: Designing HVAC systems with redundancy and fault-tolerant features to ensure continuous operation of the data center in the event of equipment failure or maintenance activities. This includes the design of backup cooling systems, automatic switchover mechanisms, and monitoring systems.
- Heat Load Calculation and Capacity Planning: Performing heat load calculations for data centers to determine the cooling requirements based on the IT equipment, power density, anticipated growth, and phasing of the construction and operational steps. Conducting capacity planning to ensure the HVAC system can accommodate future expansions and upgrades. Performing HVAC loads for admin and common sections of the facility.
- Energy Efficiency and Sustainability: Implementing energy-efficient HVAC design strategies, such as utilizing economizers, variable speed drives, energy recovery systems, and optimizing airflow management techniques, to minimize energy consumption and support sustainability initiatives.
- Air Quality and Filtration: Ensuring the data center's air quality is maintained at optimal levels by designing appropriate filtration systems and implementing air quality monitoring mechanisms. Addressing concerns related to particulate matter, humidity control, and contaminant removal to protect sensitive IT equipment.
- Coordination with Electrical and Mechanical Systems: Collaborating with electrical engineers and mechanical engineers to integrate the heat rejection and HVAC system seamlessly with the electrical infrastructure, UPS systems, emergency power systems, fire suppression systems, and other critical infrastructure components.
Minimum Qualifications:
- Bachelor's Degree with 8+ years of relevant experience or demonstrated equivalency of experience and or education.
- Experience in data center mechanical and electrical equipment installation and operation.
- P. E. registration is required.
Preferred Qualifications:
- A bachelor's degree in mechanical engineering, HVAC engineering, or a related field from an accredited university is typically required. Preference would be given to candidates with a master's degree or advanced coursework in HVAC systems or energy management.
- Knowledge of data center TER Standard Topology as per Uptime Institute, TIA 942, ANSI/BICSI 002.
- Professional certifications related to HVAC engineering, such as Certified Energy Manager (CEM), Building Energy Modeling Professional (BEMP), or Leadership in Energy and Environmental Design (LEED) accreditation, would be advantageous.

Search Mechanical Engineer Jobs in ArizonaMechanical Engineer Jobs in Arizona: Frequently Asked Questions
Which companies sponsor visas for mechanical engineers in Arizona?
Several large employers in Arizona have documented histories of sponsoring mechanical engineers. Honeywell Aerospace in Phoenix and Tempe, Raytheon Technologies in Tucson, Intel in Chandler, and General Dynamics Mission Systems are among the firms that regularly file sponsorship petitions for engineering roles. Smaller precision manufacturing and semiconductor equipment companies in the East Valley also sponsor, though less consistently than the major defense and technology employers.
Which visa types are most common for mechanical engineer roles in Arizona?
The H-1B visa is the most common visa for mechanical engineers in Arizona, as the role qualifies as a specialty occupation requiring at least a bachelor's degree in mechanical engineering or a closely related field. Engineers from Canada and Mexico may also pursue TN visa status, which can be obtained at a port of entry. Australian engineers qualify for the E-3 visa, which offers a faster and cap-independent alternative to the H-1B visa for eligible candidates.
Which cities in Arizona have the most mechanical engineer sponsorship jobs?
Phoenix and the surrounding East Valley cities, including Chandler, Tempe, Scottsdale, and Mesa, account for the largest share of mechanical engineering sponsorship activity in Arizona. This reflects the concentration of aerospace, defense, and semiconductor employers in that corridor. Tucson is the second most active market, driven by Raytheon, defense-adjacent contractors, and the University of Arizona's research and commercialization ecosystem.
How to find mechanical engineer visa sponsorship jobs in Arizona?
Migrate Mate is built specifically for international engineers seeking sponsored roles in the U.S. You can filter by state and job category to surface mechanical engineer positions in Arizona from employers that have indicated sponsorship willingness. This is more targeted than general job search approaches because the platform is designed around visa sponsorship, reducing time spent researching employer eligibility across hundreds of listings.
Are there any Arizona-specific factors that affect mechanical engineer visa sponsorship?
Arizona's strong aerospace and defense sector means many mechanical engineering roles at firms like Raytheon and General Dynamics require security clearances, which can complicate or delay sponsorship for non-citizens. Separately, Arizona State University and the University of Arizona produce large graduating classes of mechanical engineers, creating a competitive local talent pool. Employers typically sponsor when they cannot fill specialized roles domestically, so targeting niche disciplines such as thermal systems, structural analysis, or MEMS fabrication often improves sponsorship prospects.
What is the prevailing wage for sponsored mechanical engineer jobs in Arizona?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
