Design and engineer the mechanical systems behind demand-flexible data center cooling. You’ll model thermal inertia and headroom dynamically, develop strategies such as setpoint moves, staging, and thermal storage, and validate predictions through instrumented field tests. Working as one team with controls engineers, you’ll quantify operational risk in degrees and margins and help turn cooling into a grid asset at civilization-scale AI infrastructure.

Location: Austin, New York, San Francisco, Seattle
Workplace: Onsite
Employment Type: Full time
Job Function: Field Service, Maintenance & Skilled Trades

Key Responsibilities

  • •Engineer the mechanical side of demand flexibility, including cooling systems that ride through load flex without thermal risk.
  • •Model thermal inertia and headroom to quantify how far and how long the plant can flex per site.
  • •Design mechanical strategies—setpoint moves, staging, and storage—to turn cooling into a grid asset.
  • •Validate models in the field using instrumented tests before the fleet runs on them.

Pay and Benefits

Salary: USD 203,000 - 232,000 annually

Key Requirements

  • •Engineered mechanical or HVAC systems for data centers or industrial plants.
  • •Modeled thermal systems dynamically (not just steady state).
  • •Ran field validation campaigns and reconciled model predictions to measurement.
  • •Quantified operating risk in terms of degrees, minutes, and margins.
  • •Worked jointly with controls engineers as one system team.
