Mechanical Lead, Capacity Delivery

Lead mechanical engineering for Fluidstack's gigawatt-scale AI data centers, owning reference design, field decisions, and execution for direct-to-chip liquid cooling systems from concept to energized. Requires prior leadership of data center or heavy industrial mechanical programs with deep liquid cooling expertise.

About the role

Role Scope

Own mechanical engineering across the portfolio: cooling plants, liquid loops, and airside from reference design to energized. Set the mechanical reference design for direct-to-chip liquid cooling and evolve it with each build's lessons. Make the field mechanical calls, routing conflicts, equipment substitutions, sequence changes, at build speed. Review consultant packages with owner-of-record rigor before they hit the field.

Responsibilities

  • Engineer gigawatts from drawing to energized, in months not years.
  • Own technical execution across every build: the drawings, the field questions, and the engineering calls that keep multiple concurrent gigawatt sites moving.
  • Engineer data centers that go up in months, not years. At that pace rework is not an option: problems get caught on paper or they cost a data hall.
  • Design it once, build it a hundred times. Every site's lessons roll into the reference design on the way to 50GW+, so each build starts ahead of the last.

Requirements

  • Led mechanical engineering for data center or heavy industrial programs.
  • Know liquid cooling at the design level: hydraulics, controls interface, redundancy.
  • Made field engineering calls under schedule pressure that held up.
  • Manage design firms with technical authority, not just contract terms.

Nice-to-Haves

  • PE license.
  • Direct-to-chip cooling.
  • Modular skid packages.
  • Hydraulic and CFD modeling.
