Job description

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 develop the actuator systems for the thermal active cooling assembly of cold plates and related thermal solutions
  • Apply electromechanical and electromagnetic engineering principles to the design and integration of active cooling mechanismsDevelop and integrate the PCB electrical interface, including connector pinout, power requirements, signal timing, and electrical-mechanical interface specifications
  • Implement and validate embedded control firmware performance for the active cooling electronics system, including control drivers, sensor data acquisition, and thermal performance feedback loop
  • Develop a controller system (PLC-type or equivalent) for the active thermal management control node (TCN)
  • Develop block diagrams for open-loop and closed-loop control systems (OLS and CLS) for thermal and actuator control applications
  • Set up and conduct electromagnetic compatibility testing, including Electromagnetic Interference (EMI) characterization and Vector Network Analyzer (VNA) measurements in collaboration with the Electrical Engineer
  • Integrate mechanical, electrical, and software subsystems into a validated active module assembly
  • Collaborate with the Mechanical Design Engineer on active module housing geometry and mechanical integration
  • Support manufacturing of active cooling components, define assembly procedures, tooling requirements, and quality acceptance criteria
  • Troubleshoot and iterate on system performance through prototype build and test cycles

Who You Are (Basic Qualifications)
  • BS in Mechatronics, Mechanical Engineering, Electrical Engineering, Computer Engineering, or Systems Engineering
  • 3+ years of electromechanical system design and integration experience
  • Strong understanding of electromechanical and electromagnetic principles including actuator design and motor control
  • Experience designing electromechanical and electromagnetic actuation systems, including solenoids, inductor coils, electric motors, and related drive electronics
  • Experience with control systems, feedback loops, and embedded controller or PLC programming
  • Experience using electronic measurement equipment including oscilloscope, DC power supply, function/waveform generator, and related bench instruments
  • Experience with Python or MATLAB-Simulink for system modeling and control algorithm development
  • Experience with PCB design and electrical-mechanical interface development
  • Experience taking electromechanical systems from concept to validated prototype

What Will Put You Ahead
  • Experience with PCB layout tools (Altium, Cadence, or equivalent)
  • Ability to develop and debug embedded firmware (C, C++, or equivalent)
  • Familiarity with thermal management applications and liquid cooling system integration
