Work with Us. Change the World. At AECOM, we're delivering a better world. Whether improving your commute, keeping the lights on, providing access to clean water, or transforming skylines, our work helps people and communities thrive. We are the world's trusted infrastructure consulting firm, partnering with clients to solve the world’s most complex challenges and build legacies for future generations. There has never been a better time to be at AECOM. With accelerating infrastructure investment worldwide, our services are in great demand. We invite you to bring your bold ideas and big dreams and become part of a global team of over 50,000 planners, designers, engineers, scientists, digital innovators, program and construction managers and other professionals delivering projects that create a positive and tangible impact around the world. We're one global team driven by our common purpose to deliver a better world. Join us. AECOM is seeking a hands-on Computational Fluid Dynamics (CFD) Engineer to join its Data Center team in our Buildings and Places (B+P) group in our Arlington, VA office; however, this position can be fully remote. This individual-contributor role is responsible for executing internal and external airflow, thermal, and equipment-discharge studies with minimal oversight. The successful candidate will convert complex simulation results into practical design actions, clearly communicate assumptions and limitations, and help establish repeatable, high-quality CFD workflows across multiple concurrent projects.

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. Key Responsibilities: - Own the full CFD study lifecycle: clarify the design question, define scope and acceptance criteria, develop the methodology, build geometry, generate the mesh, establish boundary conditions, solve, verify convergence, post-process results, and issue technical reports. - Perform internal data hall studies addressing rack inlet temperatures, airflow distribution, hot- and cold-aisle containment, bypass and recirculation, raised-floor or slab configurations, cooling-unit placement, rack density, failure modes, and capacity-expansion scenarios. - Perform external studies for cooling towers, chillers, dry coolers, generator and boiler exhaust, mechanical yards, relief air, outdoor-air intakes, heat rejection, plume behavior, short-circuiting, and thermal re-entrainment. - Conduct steady-state and transient analyses for cooling-system outages, equipment failures, load changes, control sequences, thermal ride-through, and other operating scenarios defined by the project team. - Develop defensible modeling assumptions using design documents, equipment data, controls narratives, weather data, commissioning information, and field measurements; identify data gaps and document their impact on conclusions. - Apply sound verification and validation practices, including mesh-sensitivity checks, mass and energy balance reviews, convergence assessment, comparison with hand calculations, and correlation to measured or monitoring data when available. - Evaluate results against project-specific criteria and relevant guidance, including ASHRAE TC 9. 9 thermal guidance and applicable client, code, and industry requirements.
