New Position

Position Overview

We are seeking a highly motivated and experiencedThermal Engineer Liquid Coolingto join ourFront-End I/O Active Thermal Solutionsteam. This role focuses on the design, simulation, validation, and optimization ofliquid-based active cooling solutionsfor high-speed interconnect and front-panel I/O systems used in data center and high-performance computing environments.

The ideal candidate will work closely with customers and cross-functional engineering teams to define thermal requirements, develop robust liquid cooling architectures, perform advanced thermal simulations, and validate designs through laboratory testing. This role deliversproduction-ready thermal solutionsthat meet performance, reliability, and manufacturability targets.

Key Responsibilities:

Design & Development

• Architect and developliquid-cooled cold platesfor high-density front-end I/O connector and interconnect applications.
• Design and optimizemicrochannel structures, flow paths, and cold plate geometriesto maximize thermal performance while minimizing pressure drop.
• Select and integrate materials compatible withhigh heat flux, corrosion resistance, and long-term reliabilityin data center environments.
• Collaborate with connector and mechanical design teams to ensuremechanical integration, tolerance alignment, and manufacturability.

Customer Engagement

• Work directly with customers to gatherthermal boundary conditions, system constraints, and performance requirements.
• Translate customer needs intothermal simulation strategies, validation plans, and design trade-offs.
• Serve as a technical interface to explain thermal concepts, design decisions, and test results.

Thermal Simulation & Analysis

• Develop and executeCFD thermal modelsusing tools such asANSYS Icepak, FloTHERM, or equivalent.
• Analyze temperature distribution, heat dissipation, and fluid flow behavior in liquid cooled front-end I/O environments.
• Performsensitivity studies and optimization analysesto ensure designs meet performance margins.

Experimental Validation

• Partner with lab and test engineers to plan and conductthermal performance and flow validation testing.
• Correlateexperimental datawith simulation results to validate and refine models.
• Conduct root-cause analysis and iterative design improvements to resolve thermal issues.

Optimization & Technical Reporting

• Optimize thermal designs consideringperformance, cost, reliability, and manufacturability.
• Prepare detailedtechnical reports and presentationssummarizing simulations, test results, and design recommendations.
• Present optimized solutions and findings to customers and internal stakeholders.
