Mechanical Engineer, Data Center Engineering & Design

Fluidstack is focused on delivering massive compute infrastructure for AI, aiming to enhance human freedom through technology. The Mechanical Engineer will lead the design and execution of mechanical systems for high-density data centers, ensuring efficient cooling and power distribution.

Responsibilities:

• Own mechanical systems end to end for AI-optimized, high-density data centers, from early concept and analytical modeling through final build and deployment
• Lead the design and evolution of mechanical and cooling systems as Fluidstack scales to multiple gigawatts
• Develop and maintain modular mechanical templates that enable rapid, repeatable global deployment
• Serve as the technical interface between internal teams and external consultants, keeping designs aligned with Fluidstack's high-density cooling and power requirements
• Build supply-chain-aware solutions so designs integrate cleanly and deploy fast

Requirements:

• You've owned mechanical design for data centers or high-density facilities, from concept and modeling through build
• You design cooling systems for AI-class density (chilled water, CDUs, direct liquid cooling) and think in modular, repeatable templates
• You manage external consultants and act as the technical bridge to internal strategy
• You design with supply chain and constructability in mind, not in a vacuum
• You want full ownership of the mechanical lifecycle at gigawatt scale
• PE license
• Direct-to-chip or liquid cooling design
• Modular or prefab template programs
• CFD (6SigmaET, Icepak)
• ASHRAE TC 9.9
