About The Position

As a Mechanical Engineer at Fluidstack, you will play a pivotal role in architecting the next generation of AI-optimized infrastructure as we scale to deliver multiple gigawatts of facilities. This is a high-impact engineering position focused on owning mechanical systems end-to-end, from early concept and analytical modeling through final build and deployment. You will lead the development of modular template designs and innovative supply-chain-aware solutions that enable rapid global deployment. Acting as the technical bridge between internal strategy and external execution, you will manage specialized partners and consultants to ensure designs integrate seamlessly with Fluidstack’s high-density cooling and power requirements. This role is designed for a problem-solver who thrives in complex environments and wants full ownership of the mechanical lifecycle for gigawatt-scale data centers.

Requirements

  • Bachelor’s degree in Mechanical Engineering.
  • 5–8 years of experience designing large-scale industrial or mission-critical facilities, specifically data centers.
  • Demonstrated expertise in high-density cooling systems, including liquid-to-chip and immersion cooling.
  • Proficiency in Revit / BIM for template creation and design development.
  • Strong analytical skills, including CFD modeling and capacity planning.
  • Proven ability to operate with extreme ownership and manage complex external relationships.

Nice To Haves

  • Professional Engineer (PE) license.

Responsibilities

  • Lead the design and evolution of mechanical systems for AI-optimized, high-density data centers.
