About This Role

Arcadis is the world's leading company delivering sustainable design,

engineering, and consultancy solutions for natural and built assets.

We are more than 34,000 people, in over 30 countries, dedicated to improving

quality of life. Everyone has an important role to play. With the power of many

curious minds, together we can solve the world’s most complex challenges and

deliver more impact together.

Role Description:

This role sits within our global business area of Resilience. Around the world,

we are feeling the effects of climate change, rapid urbanization, and loss of

biodiversity. The rate at which we are seeing large-scale, unforeseen events

such as floods and wildfires, is becoming more frequent. We are here to steward

and safeguard our natural environment and water resources while supporting and

powering our world for the benefit of current and future generations.

Key Responsibilities:

In this role, you will leverage advanced computational fluid dynamics (CFD)

tools to model and analyze airflow patterns, thermal performance, and

environmental conditions within data center facilities and across the

surrounding site. Additional responsibilities include:

* Internal CFD Modeling: Develop, run, and analyze internal CFD simulations for

data center white-space and equipment-room environments. Model airflow

distribution and thermal performance around server racks, containment

systems, raised-floor or overhead air distribution, and cooling systems

including CRAC/CRAH units, direct-to-chip cooling, liquid-cooling support

systems, and free-cooling arrangements. Evaluate supply and return airflow,

rack inlet temperatures, hot-air recirculation, bypass airflow, pressure

distribution, hot spots, and cooling-system effectiveness, and recommend

improvements to equipment layout, airflow management, and cooling

performance.

* External CFD Modeling: Develop, run, and analyze site-scale CFD simulations

for data center campuses and other mission-critical facilities. Evaluate

atmospheric wind flow around buildings, equipment-yard airflow, cooling-tower

or dry-cooler heat rejection and recirculation, generator and other equipment

exhaust dispersion, outdoor-air intake exposure, and the effects of adjacent

buildings, terrain, screening, louvers, and site obstructions. Assess adverse

wind directions and operating conditions, identify recirculation or

plume-interaction risks, and recommend improvements to equipment placement,

intake and discharge separation, screening, and site configuration. Conduct a

climate analysis and perform a Probability Risk Assessment study.

* Design Optimization: Provide actionable insights and recommendations to

optimize airflow distribution, reduce hot spots, and enhance energy

efficiency. Collaborate closely with architects and engineers to seamlessly

integrate optimized designs into both construction projects and operational

workflows.

* Collaboration and Support: Partner with cross-functional teams, including

mechanical, electrical, and HVAC engineers, to ensure designs align with

performance and regulatory standards. Additionally, assist in troubleshooting

operational airflow and thermal management issues in existing facilities to

maintain optimal system performance.

* Documentation and Reporting: Create detailed reports, visualizations, and

presentations to effectively communicate simulation findings and proposed

solutions to stakeholders. Additionally, maintain accurate records of

modeling assumptions, methods, and outcomes to ensure transparency and

consistency in the documentation process.

* Research and Development: Stay up to date with the latest advancements in CFD

modeling techniques, software, and data center cooling technologies.

Continuously identify opportunities to integrate emerging tools and methods

that can enhance modeling accuracy and improve overall efficiency.

Required Qualifications:

* MS degree in Mechanical Engineering, Aerospace Engineering, Thermal Sciences,

or a related field

* 2 or more years of post-graduate experience in CFD modeling, thermal

analysis, or HVAC design, preferably for data centers, mission-critical

facilities, or high-performance buildings, including practical experience

with internal and external CFD studies

Key Skills & Attributes:

To succeed in this role, you must have a solid understanding of thermodynamics,

fluid mechanics, heat transfer, turbulence, and atmospheric or environmental

flow principles, together with knowledge of data center cooling technologies and

industry best practices. Experience with both internal CFD for data hall airflow

and thermal management and external CFD for site wind, heat rejection, and

exhaust dispersion is strongly preferred. Proficiency in one or more primary CFD

platforms, including ANSYS Fluent, Cadence Reality DC Design Pro (Formerly known

as 6SigmaDCX), HELYX, STAR-CCM+, SimScale, OpenFOAM, and FLOW-3D., is required.

Experience should include geometry preparation, meshing, boundary-condition

development, turbulence modeling, solution monitoring, verification, sensitivity

analysis, and interpretation of results. Familiarity with FLOW-3D is considered

a plus but is not required. Proficiency in Python or MATLAB for data analysis

and automation is highly desirable. Strong analytical, problem-solving,

communication, collaboration, and project-management skills are essential. Mut

be proficient in ANSYS Fluent, Cadence Reality DC Design Pro (Formerly known as

6SigmaDCX), STAR-CCM+, HELYX, SimScale, OpenFOAM, and FLOW-3D. Experience

developing 3D geometry from engineering and architectural drawings and

simplifying models in Rhino for CFD analysis.

Preferred Qualifications:

* PhD in Mechanical Engineering, Aerospace Engineering, Thermal Sciences, or a

related field

* Professional Engineer (PE) license or equivalent certifications

* Demonstrated experience evaluating building aerodynamics, thermal or exhaust

recirculation, plume dispersion, outdoor-air intake exposure, and

equipment-yard performance for data center or mission-critical sites.
