About the role

Role focused on engineering the mechanical side of demand flexibility for data centers and industrial plants, including modeling thermal systems, designing strategies for cooling as a grid asset, and validating models in the field.

Responsibilities

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

Qualifications

  • You've engineered mechanical or HVAC systems for data centers or industrial plants.
  • You've modeled thermal systems dynamically, not just at steady state.
  • You've run field validation campaigns and reconciled model to measurement.
  • You quantify risk in operating terms: degrees, minutes, and margins.
  • You work jointly with controls engineers as one system team.
