Location: Mountain View
Workplace: Onsite
Employment Type: Full time
Job Function: Data Science & Machine Learning
Seniority: Mid level

Key Responsibilities

  • •Own thermal design and analysis for deployable data center cooling systems, spanning rack/chip level through full facility cooling, heat rejection, and liquid cooling.
  • •Use first-principles modeling (hand calcs, spreadsheets, MATLAB/Python) to determine the right analysis level before detailed design.
  • •Define cooling architecture and heat-rejection strategy (e.g., CRAH/CRAC, economization, chilled water plants, dry coolers, CDUs, rear-door heat exchangers, direct-to-chip/immersion).
  • •Develop approaches for high-density racks and trade off air, liquid, and hybrid cooling for transportable systems in austere, high-ambient environments.
  • •Lead thermal FEA/CFD and system models, predict facility performance, set operating limits, and support prototype builds, field testing, commissioning, and root-cause analysis.

Pay and Benefits

Salary: USD 160,000 - 211,000 annually

Key Requirements

  • •MS or higher in mechanical engineering, applied physics, or related field focused on heat transfer, fluid dynamics, and HVAC
  • •In-depth understanding of heat transfer and fluid dynamics
