Advanced Product Design Engineer

Your Job:

We are seeking an Advanced Product Design Engineer to join NPD Engineering in Tamsui District, New Taipei City, Taiwan. This experienced, hands-on role develops next-generation cooling solutions for optical modules, related optical communication technologies, and AI computing platforms.

About the Role:
This position leads front-end concept development, architecture exploration, rapid prototyping, and proof-of-concept validation for advanced thermal and liquid cooling solutions. The engineer will independently transform ideas into validated designs while working closely with Thermal Engineering, manufacturing, suppliers, and cross-functional teams.
The role requires strong product design capability, practical thermal knowledge, and concept-to-prototype execution to meet thermal performance, reliability, manufacturability, and cost targets.

What you will do:

Front-End Concept Development

• Develop cooling concepts for next-generation optical modules, optical communication technologies, and AI computing platforms.
• Lead feasibility studies, architecture exploration, rapid prototyping, and proof-of-concept validation.
• Independently drive design decisions from early concept through validated prototype.

Advanced Product Design

• Create 3D models, assemblies, and engineering drawings using Siemens NX.
• Apply GD&T, tolerance analysis, material selection, and design-for-manufacturing.
• Translate customer, system, and thermal requirements into practical product designs.

Thermal & Liquid Cooling Solutions

• Design cold plates, microchannels, manifolds, flow paths, TIM interfaces, and high heat-flux cooling assemblies.
• Collaborate with Thermal Engineering teams to define analysis needs and translate simulation and test findings into design decisions; hands-on CFD execution is not required.
• Optimize thermal performance, flow distribution, pressure drop, reliability, and package integration.

Prototype, Validation & Manufacturing

• Coordinate thermal, flow, pressure, leak, mechanical, and reliability testing.
• Lead root-cause analysis, corrective actions, and design improvement based on validation results.
• Evaluate brazing, laser welding, friction stir welding, diffusion bonding, and other joining methods based on manufacturing constraints and design limits.
• Collaborate with suppliers and manufacturing teams to confirm feasibility and scalability.

Who you are (Qualifications)

• Bachelor's or Master's degree in Mechanical Engineering, Thermal Engineering, or a related engineering discipline.
• 7+ years of product design, thermal-mechanical development, or advanced engineering experience.
• Strong Siemens NX capability for 3D modeling, assembly design, and engineering drawings.
• Experience independently driving products from concept through prototype validation.
• Knowledge of heat transfer, fluid mechanics, thermal management, engineering materials, GD&T, and tolerance analysis.
• Strong problem-solving, ownership, communication, and cross-functional collaboration skills.

What will put you ahead:

• Hands-on experience with liquid cooling, cold plates, optical module cooling, microchannels, manifolds, flow balancing, or pressure-drop optimization.
• Knowledge of Thermal Interface Material (TIM) selection, thermal contact resistance, compression behavior, and high-power thermal design.
• Experience developing thermal solutions for next-generation optical modules, high-speed optical communication products, and future connectivity technologies.
• Strong thermal engineering knowledge with the ability to work closely with Thermal Engineering teams to define cooling requirements, review analysis results, and drive successful thermal solution development.
• Ability to interpret thermal simulation and test data and convert findings into product improvements.
• Understanding of vacuum brazing, laser welding, friction stir welding, diffusion bonding, and related joining design limitations.
