Job description

Are you passionate about pushing the boundaries of data center cooling through advanced CFD analysis and innovative mechanical system design? Do you want to own the technical direction of CFD modeling standards across a global engineering organization? Are you ready to lead the development of thermal solutions that directly influence how we scale our infrastructure worldwide?

Key Job Responsibilities

CFD Modeling & Technical Leadership

• Defining the CFD modeling approach for innovative data center designs; developing validation methodologies and establishing best practices for the broader engineering team
• Leading internal CFD studies for data halls and electrical rooms, including steady‑state thermal analysis under N unit failure scenarios and N+1 operational conditions at full load
• Performing transient thermal studies to assess IT equipment survivability during concurrent power failure and unit failure events, including time‑to‑recovery analysis post power restoration
• Owning external CFD studies encompassing full campus mechanical and electrical plant, including adjacent industrial complexes and site obstructions, and leading thermal plume recirculation analysis to understand heat dissipating equipment impact on building and equipment intake temperatures
• Performing air emissions and contaminant dispersion modeling to quantify generator exhaust ingestion into building intakes
• Proposing and validating mitigation strategies where results indicate exceedance of defined limits, and implementing solutions into the CFD model for verification
• Managing external CFD consultants including review and approval of return briefs, model inputs, assumptions, and boundary conditions prior to solving

Mentorship & Team Development

• Providing mentoring, guidance and developing junior engineers in CFD techniques, mechanical design best practices, and professional growth
