Job Summary

Senior mechanical engineer leading cooling strategy for FluidStack’s AI data centers. Owns design from chip-level interfaces to chiller plants across multi-site portfolio, coordinating with electrical, controls, structural, and construction teams. Shapes modular, prefabricated thermal assemblies, drives energy-efficiency innovations, and guides a growing engineering team to meet aggressive deployment timelines.

Location: Austin, New York, San Francisco

Workplace: Onsite

Employment Type: Full time

Job Function: Design (Product/UX/UI/Visual)

Seniority: Sr. Manager level

Key Responsibilities

•Define and own FluidStack’s mechanical cooling strategy across the portfolio – from chip-level thermal interfaces through CDU/coolant distribution, chilled water plants, and heat rejection to atmosphere.
•Develop and maintain the mechanical basis of design, master specifications, standard drawings, and sequence of operations for all cooling systems.
•Drive key architectural decisions: coolant chemistry (e.g. clean PG25 circuits), chiller topology (air-cooled vs. water-cooled centrifugal), CDU elimination strategies, and medium-voltage chiller integration.
•Lead innovation on energy efficiency – free cooling, water-side economizers, waste-heat reuse – targeting best-in-class PUE and WUE across all sites.
•Establish thermal and hydraulic design criteria for high-density GPU deployments (75–150+ kW/rack) spanning direct liquid cooling, rear-door heat exchangers, and hybrid air/liquid architectures.

Travel: Medium travel
