What You Will Do (Job Description)

Liquid Cooling System Design:

* Design and develop advanced liquid cooling solutions, including cold plates, tubing, and manifold systems for highspeed IO solutions.

Mechanical Design:

* Design of cooling system components, including housings, quick-connect fittings, and structural interfaces, ensuring manufacturability and robustness.

* Develop detailed CAD models and engineering drawings for thermal and mechanical components, adhering to industry standards.

* Conduct structural and thermal stress analyses (e.g., FEA) to ensure the mechanical reliability of designs under thermal expansion, vibration, and pressure conditions.

End-to-End Development (Concept to Production):

* Lead product development from initial concept and prototyping to mass production.

* Define product requirements, create design specifications, and establish validation plans for thermal and mechanical systems.

* Collaborate with cross-functional teams (thermal, mechanical, electrical, manufacturing) to ensure a seamless transition from design to production.

* Develop DFX (Design for Manufacturability, Reliability, and Testing) strategies to optimize production efficiency and product quality.

* Identify and mitigate risks throughout the product lifecycle, including design iterations, testing, and production ramp-up.

Cross-Functional Collaboration:

* Act as a technical lead, coordinating efforts among cross-functional teams, suppliers, and production facilities.

* Provide technical guidance to ensure manufacturability, reliability, and scalability of liquid cooling and mechanical system.

Innovation and Compliance:

* Stay updated on industry trends in liquid cooling, mechanical design, and sealing technologies, including advanced sealing materials and methods.

Who You Are (Basic Qualifications)

* Bachelor's or Master's degree in Mechanical Engineering, Thermal Engineering, or a related field.

* 5+ years of experience in thermal and mechanical design.

* Proficiency in CAD software (e.g., NX, Creo, Solid Works).

* Familiarity with End-to-End Development (Concept to Production)

* Experience with manufacturing processes (e.g., CNC machining, stamping, plating, injection molding, LSR molding).

* Experience with developing test requirements for mechanical & thermal designs as well as reviewing thermal and reliability test reports.

* Excellent problem-solving and analytical skills, able to deeply analyze testing failure mode while focusing on manufacturability and quality control.

* Experience performing tolerance stack-up analysis for CAD.

* Experience working with international colleagues and suppliers, which may require meetings in the early morning or evening.

What Will Put You Ahead

* Hands-on experience with liquid cooling systems: cold plates, CDU, quick-connect fittings, tubing, and manifold assemblies.

* Expertise in sealing technologies, including material selection, sealing design (e.g., O-rings, gaskets), and leakage prevention.

* Strong…
