Sr. Mechatronics Engineer

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 Boundary Cool™ 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.
