Mechanical Design Engineer - Power Modules and Power Packages

About the role

We are seeking a skilled and detail-oriented Mechanical Designer to join our Power Modules and Power Packages R&D team. The role focuses on the mechanical design and integration of advanced power modules and discrete packages, with a strong emphasis on assembly process compatibility, thermal management, reliability, and manufacturability. The ideal candidate will contribute to the development of next-generation solutions based on SiC and GaN technologies for traction and industrial applications.

What you will do

Design mechanical structures for power modules and packages, including housings, substrates, interconnects, and cooling systems.

Integrate mechanical design with assembly process requirements, including:

Sintering (Ag or Cu)

Gel-filling and potting

Press-fit and soldering

Wire bonding and clip bonding

Encapsulation and molding

Large area soldering / sintering

Collaborate with process engineers to ensure mechanical designs are compatible with automated and semi-automated assembly lines

Develop 3D CAD models and detailed drawings using tools such as SolidWorks, Inventor or CATIA

Perform mechanical simulations (e.g., stress, vibration, thermal expansion) using FEA tools (e.g., ANSYS, COMSOL) is a nice to have

Support prototyping, testing, and validation of mechanical designs in collaboration with internal labs and external partners

Contribute to design-for-manufacturing (DFM) and design-for-reliability (DFR) initiatives

Interface with suppliers and manufacturing teams to ensure feasibility and quality of mechanical components

Document design processes, specifications, and test results in compliance with internal standards and industry regulations

Coordinate and manage design documentation activities across the mechanical design team, ensuring proper document control, version management, release processes, and data consistency

What you will bring

Bachelor’s or Master’s degree in Mechanical Engineering or related field

3+ years of experience in mechanical design, preferably in power electronics or semiconductor packaging

Proficiency in CAD and FEA tools

Solid understanding of materials used in power electronics (metals, ceramics, polymers) and their mechanical/thermal properties

Experience with assembly processes relevant to power modules and packages

Familiarity with thermal management techniques (e.g., heat sinks, TIMs, liquid cooling)

Knowledge of reliability standards (e.g., JEDEC, IEC) and environmental testing

Strong problem-solving skills and ability to work in cross-functional teams

Fluent in English; Chinese would be a plus

Available to travel for 25% of working time

Preferred Skills

Experience with SiC , GaN or IGBT -based power modules

Background in traction or industrial applications

Exposure to processes and manufacturing or advanced packaging technologies

Knowledge of PCB design and integration

What We Offer

Opportunity to work on cutting-edge technologies in a collaborative and innovative environment

Strong connection with academic and industrial partners

Career development in a global organization with a focus on sustainability and electrification
