Job Overview by Ladders

Qualifications

  • 5-7 years of experience in mechanical or HVAC system engineering, specifically for data centers or industrial applications.
  • Demonstrated ability in dynamic thermal modeling, showing understanding beyond steady-state scenarios.
  • Proven experience in executing field validation campaigns that reconcile modeled data with real-world measurements.
  • Strong capability to quantify operational risks in measurable terms such as degrees and time.
  • Collaborative skills to work integratively with controls engineers as part of a cohesive system team.
  • Bonus qualifications include expertise in liquid cooling, dynamic simulation tools (like Modelica or TRNSYS), computational fluid dynamics (CFD), and depth in psychrometrics.

Responsibilities

  • Engineer mechanical solutions for cooling systems with thermally risk-free load flexibility.
  • Model and quantify thermal inertia and headroom for adaptability at various sites.
  • Design mechanical strategies for effective cooling that optimize grid asset performance.
  • Conduct field tests to validate theoretical models and ensure reliability before real-world application.

Benefits

  • A commitment to pay equity and transparency.
  • Opportunities for professional development and exceptional growth.
  • Flexible work environment to accommodate a diverse range of talent.
Full Job Description
Role Scope
  • 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.
What We're Looking For
  • The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
  • 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.
  • Bonus: Liquid cooling. Dynamic simulation (Modelica, TRNSYS) or CFD. Thermal storage. Psychrometrics depth.


We are committed to pay equity and transparency.
