## About the Role

* Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a closely related engineering discipline.
 * 6+ years of hands-on CFD experience, including direct application to data centers, mission-critical facilities, or similarly complex thermal-management environments.
 * Proficiency with at least one data-center or general-purpose CFD platform, such as Cadence 6SigmaDCX, Ansys Fluent, Ansys CFX, or OpenFOAM, and the ability to learn and apply project-required tools.
 * Strong fundamentals in fluid mechanics, heat transfer, thermodynamics, turbulence modeling, and HVAC system operation.
 * Experience modeling both internal environments, such as IT spaces and containment systems, and external environments, such as mechanical yards, cooling equipment, intakes, and exhaust discharges.
 * Working knowledge of data center cooling architectures, HVAC systems, redundancy concepts, controls and failure scenarios, and common thermal performance metrics.

Preferred Qualifications:

 * Bachelor's in Mechanical Engineering
 * Professional Engineer (PE)
 * Experience with US codes and standards.
 * Demonstrated success independently delivering CFD studies from scoping through final report, including geometry preparation, meshing, solver setup, convergence assessment, post-processing, and engineering interpretation.
 * Ability to develop appropriate boundary conditions from design information and equipment performance data, and to explain the sensitivity of results to key assumptions.
 * Strong technical writing, visualization, and presentation skills, with the ability to communicate complex results to engineering teams, project managers, and clients.

## Description

* 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.
 * Translate findings into prioritized, actionable recommendations for equipment selection, airflow management, containment, intake/exhaust separation, controls, phasing, redundancy, and operational resilience.
 * Prepare concise, client-ready reports and visualizations that clearly communicate methodology, assumptions, scenarios, results, risks, limitations, and recommended next steps.
 * Present findings and coordinate directly with multidisciplinary project teams to resolve issues and confirm implementation of recommendations.
 * Contribute to standardized templates, modeling procedures, quality-control checklists, libraries, and lessons learned; support technical knowledge sharing and mentoring of less-experienced staff.
