Senior Engineer – Computational Fluid Dynamics (CFD) | Data Center

Role Overview We're seeking a Senior CFD Engineer to lead fluid dynamics and thermal modeling for data center projects across two scales — facility-level airflow and thermal management inside the data center, and site-level modeling including cooling infrastructure, thermal plumes, and grid/energy integration. This is a hands-on technical role delivering high-quality CFD analysis in support of Sunstripe's data center engineering practice.

Key Responsibilities

Facility-Level Modeling

Perform CFD modeling of data center airflow and thermal environments — including hot/cold aisle containment, rack-level cooling, raised floor plenum, and CRAC/CRAH unit performance Model and optimize cooling system configurations — air-side, liquid-cooled, and hybrid systems — to support facility design and performance validation Conduct thermal risk assessments, identify hotspots, and develop mitigation strategies across a range of data center typologies (hyperscale, colocation, edge) Support equipment layout, rack density planning, and cooling infrastructure sizing through simulation

Site-Level Modeling

Perform site-level CFD analysis including cooling tower thermal plume dispersion, external airflow, and site microclimate effects Support energy and thermal modeling for data center grid and utility integration, including waste heat recovery and thermal load forecasting Collaborate with power systems engineers on data center grid integration studies, bridging thermal and electrical modeling

General

Prepare detailed technical reports, simulation outputs, and visualizations for client and internal stakeholders Drive tool and methodology development across the CFD practice Provide technical guidance and mentorship to junior engineers Ensure compliance with relevant data center standards (ASHRAE, TIA-942, Uptime Institute)

Requirements

Bachelor's or Master's in Mechanical Engineering, Aerospace Engineering, Thermal Engineering, or related field Solid hands-on experience in CFD modeling, with demonstrated application to data center thermal and airflow analysis Proficiency across industry CFD tools — Ansys Fluent, Ansys CFX, 6 Sigma Room / Future Facilities, and Open FOAM Experience with both facility-level (rack, aisle, room) and site-level (cooling tower, plume, microclimate) modeling Familiarity with data center cooling systems — air-side economization, liquid cooling, CRAC/CRAH, cooling towers Knowledge of relevant data center standards (ASHRAE TC 9.9, TIA-942, Uptime Institute Tier classifications) Strong analytical, written, and visualization skills — able to communicate complex simulation outputs clearly to engineering and client audiences Ability to work independently and manage own deliverables within project timelines
