AI Factory - Liquid Cooling Expert

The AIF Liquid Cooling Expert is a Senior Technical contributor for Siemens AI Factory program, responsible for defining and advancing compute-side liquid cooling architectures across AI Factory and data center environments. This role integrates physical and digital cooling technologies and collaborates closely with multi-disciplinary teams to deliver scalable, reference-ready cooling solutions for Siemens portfolios and customers.

You’ll make an impact by:

• Leading the compute-side cooling strategy for the AI Factory (AIF) program, collaborating with business and technical experts across controls, simulation, air handling, power, and compute.
• Designing and integrating both physical cooling infrastructure (primary and secondary loops, cold plates, manifolds, valves, pumps, CDUs) and digital simulations, including hydraulic system simulation, thermal/ CFD simulation.
• Co-creating with peers across disciplines to optimize Siemens reference architectures and customer-specific AI Factory and data center designs.
• Creating next-generation cooling concepts using simulation tools such as Amesim, Modelica, STAR-CCM+, leveraging automation and controls through PLCs.
• Developing scalable system designs, reusable libraries, and automation-ready assets deployed across Siemens portfolios and customer solutions, including AI-assisted design workflows.
• Incorporating emerging code and standards from OCP, ASHRAE, UL, etc. into forward-looking cooling designs while operating in fast-paced, multi-disciplinary environments.
• Reducing complex cooling systems into reference designs and foundational guidelines enabling consistent execution across portfolio, advanced development, and R&D teams.

Core Competencies:

• Liquid Cooling Systems Expertise:
  Deep expertise in direct-to-chip and immersion cooling technologies and cold plate, CDU architectures. Familiarity with hydraulic and CFD simulations.
• Cooling System Architect:
  Leads physical and digital liquid cooling designs for AI Factory and data center environments, considering hydraulic and thermal performance, reliability, and efficiency.
• Scalable Design Strategy:
  Translates complex cooling systems into reusable, reference-ready architectures.
• Standards-Driven Design:
  Integrates emerging code and standards from OCP, ASHRAE, UL, etc. into future-ready solutions.
• Collaboration & Influence:
  Operates effectively across fast-paced, multi-disciplinary teams.

Basic Qualifications:

• Bachelor’s degree in Mechanical Engineering, Thermal Engineering, or related field.
• 8+ years of experience in liquid cooling, thermal systems, or data center cooling design.
• Hands-on experience with end-to-end compute-side cooling system design, hydraulics and thermal system modeling.
• In-depth knowledge of control and monitoring requirements for data center cooling systems
• Ability to travel domestically up to 90% in the first 6 months and internationally as required.
• Legally authorized to work in the United States on a continual and permanent basis without company sponsorship

Preferred Qualifications:

• Advanced degree (Master’s or PhD) in thermal, mechanical, or related engineering discipline.
• Experience designing liquid cooling systems for AI, HPC, or large-scale data center environments, both mechanical and controls.
• Prior experience in modular construction methods for mechanical and/or cooling design in data centers
• Hands-on experience with Siemens modeling, PLM, or automation platforms.
