Mechanical Engineer (Manifolds​/Liquid Cooling

Mechanical Engineer

We are seeking a highly skilled Mechanical Engineer with deep expertise in CFD and FEA to serve as the Subject Matter Expert (SME) for fluid flow & pipe stress analysis, airflow, thermal, and structural analysis across our data center infrastructure product portfolio, including manifolds and air handling unit (AHU) designs.

This role will play a critical part in product development, analytical validation, and customer-facing engineering support, working closely with Product Development Teams, Sales Engineering, and Applications teams to optimize product performance, reliability, and manufacturability across multiple platforms.

CFD & FEA Technical Leadership

• Act as the primary SME for CFD and FEA analysis across all relevant product platforms.
• Perform and interpret CFD simulations for airflow distribution, pressure drop, thermal performance, and heat rejection in:
• Cooling and fluid manifolds
• Air Handling Units (AHUs)
• Related data center airflow and thermal management components
• Conduct FEA simulations to evaluate:
• Structural integrity
• Vibration, fatigue, and thermal stress
• Material and thickness optimization for manufacturability and cost
• Develop, validate, and maintain analysis methodologies, assumptions, and best practices.

Product Development Support

• Collaborate with mechanical design engineers from concept through production release.
• Influence product architecture by providing data-driven design recommendations.
• Support rapid design iterations through simulation-led decision making.
• Validate designs against industry standards and internal performance criteria.

Sales Engineering & Applications Support

• Provide engineering analysis support for customer-specific applications and bids.
• Assist Sales Engineering with:
• Performance validation
• Custom configurations
• Technical responses and customer presentations
• Translate complex simulation results into clear, customer-ready insights.

Testing & Validation

• Support correlation between simulation and analytical/physical test results.
• Guide prototype testing plans and instrumentation strategies.
• Identify gaps between analytical predictions and real-world performance and drive improvements.

Process & Knowledge Development

• Standardize CFD/FEA workflows, templates, and documentation.
• Mentor junior engineers and cross-functional teams on simulation fundamentals.
• Stay current with emerging data center cooling technologies and analysis techniques.

Additional Expectation

• Remain compliant with the Code of Conduct and Policies which includes the Kingspan Group Compliance Policy.
• Ensure that all duties related to product compliance are adhered to in accordance with the Product Compliance Policy, Laws, Regulations, and market demands.
• Responsible for all tasks to achieve compliance goals and demands of the Compliance Management System.
• Must raise concerns related to the Compliance Management System to their supervisor, manager, or any member of the Leadership Team, or through the confidential whistle blower service.

What You'll Bring

• Bachelor's degree in mechanical engineering (required)
• Hands-on, practical experience with CFD and FEA tools, specifically applied to HVAC and thermal-fluid systems for Data Centers or related industry
• Strong understanding of:
• Fluid dynamics and heat transfer
• HVAC systems and airflow management
• Structural mechanics and materials
• Proven ability to perform independent, end-to-end simulation work, from setup through interpretation

Preferred Software & Tools

• CFD: ANSYS Fluent/CFX, Solidworks Flow Sim, Autodesk CFD, OpenFOAM or similar
• FEA: ANSYS Mechanical, Abaqus, NASTRAN or similar
• CAD tools such as On-Shape, Solid Works, Creo, or equivalent
• Scripting or automation (Python, journal files, macros) is a plus

Preferred Experience (Nice to Have)

• Experience in data center infrastructure, Liquid Cooling & HVAC equipment
• Familiarity with ASHRAE guidelines related to data centers
• Experience supporting customer-facing engineering or pre-sales efforts
• Master's or PhD degree in Mechanical Engineering (Thermal/Fluids or Structural focus)

Key Competencies

• Strong analytical thinking and problem-solving skills
• Ability to balance simulation accuracy with project timelines
• Clear technical…
