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

• Develop and maintain modular mechanical templates to support rapid, repeatable global deployment.

• Serve as the technical interface between internal teams and external consultants, ensuring alignment with Fluidstack requirements.

• Ensure mechanical designs integrate seamlessly with high-density cooling and power architectures.

• Own mechanical systems from initial concept and analytical modeling through final build and execution.

• Apply strong analytical judgment through CFD modeling and capacity planning to inform design decisions.

• Hold external partners accountable for technical excellence, while remaining adaptable as project needs evolve.

Basic Qualifications

• 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.
