Sr. Mechanical Engineer - Thermal

Your Job

As part of Molex's strategic investment in CAEPlus and the ongoing development of next-generation AI data center thermal management solutions, this position will operate in a unique collaboration model between the two organizations.

While employed by Molex and receiving all Molex employment benefits, the successful candidate will work closely with the CAEPlus team and focus primarily on advancing CAEPlus technologies, products, and innovation initiatives.

This role offers the entrepreneurial environment of a growing technology venture combined with the resources, stability, and engineering expertise of a global industry leader.

This role leads the mechanical design, product validation, and manufacturing development of BoundaryCool™ thermal management solutions for the CAEPlus Phase I program.

The engineer will own the detailed design of cold plates, active module integration geometry, and manufacturing drawings - driving the full product development lifecycle from concept through prototype validation.

Working directly with the CAEPlus founder and cross-functional program team, this individual will apply expertise across precision machining, materials, and thermal hardware design to bring a breakthrough active cooling platform to market.

What You Will Do


* Design and apply advanced fluid dynamic concepts into the active thermal management system to enhance convective heat transfer performance of cold plates and related thermal solutions


* Develop and validate CFD simulations of the active thermal management system, including turbulence modeling, Conjugate Heat Transfer (CHT) analysis, heat transfer coefficient improvement, and flow distribution characterization


* Design and execute single and multi-cold plate flow loop test protocols - measuring thermal resistance (Rth K/W), flow impedance, and pressure drop (ΔP) across target flow rate range, consistent with Open Compute Project (OCP) standards


* Design server chassis-level and rack-level test rig configurations for NVIDIA NVL-class GPU load simulation


* Set up and operate flow loop test rig (coolant loop assembly, instrumentation, leakage detection, and data acquisition system)


* Install and calibrate thermal instrumentation including thermocouples, pressure transducers, flow meters, and power measurement equipment


* Correlate CFD simulation results with experimental thermal test data and iterate on the active cooling system to improve performance


* Collaborate with Mechanical Engineers and CAD Designers on cold plate channel geometry and active cooling system design


* Develop thermal test protocols, acceptance criteria, data acquisition procedures, and documentation of best practices for simulation and testing


* Generate performance data package documenting Rth, ΔT, ΔP, and flow uniformity for customer qualification


* Specify fluid fitting requirements and standards, including Universal Quick Disconnects (UQD), G1/4" BSP...
