Minimum 5 years of experience designing electro-mechanical systems or capital equipment.
Strong hands-on experience in precision mechanical assemblies and PCB support structures.
Proficiency with 3D CAD software (SolidWorks, Creo) and GD&T.
Experience with FEA and/or CFD analysis tools.
Knowledge of mechanical integration in complex systems, including PCB design, EMN creation, thermal management, DFM/DFA, and interconnect systems.
Familiarity with Agile development, Oracle PLM systems, and cross-functional collaboration for system and PCB integration.
Experience supporting products through development and production cycles.
Electromechanical applications experience in semiconductor or related industries.

Nice To Haves

Semiconductor equipment or automated handling/test systems.
Experience with suppliers and manufacturing teams.
Exposure to motion systems, thermal management, electronic packaging, or PCB-level mechanical integration.

Responsibilities

Lead mechanical design for PCB assemblies, including component mounting, board support structures, thermal management, and integration within test equipment.
Design precision electro-mechanical systems such as motion mechanisms, structural components, and enclosures.
Develop 3D CAD models, detailed drawings, tolerance analyses, and BOMs for mechanical and PCB components.
Support system integration, verification, and qualification testing during new product development.
Perform structural and thermal analysis using FEA and CFD tools, including thermal validation for PCB assemblies.
Investigate failures and implement corrective design actions.
Support mechanical integration of semiconductor test cells, including tester interfaces, device handlers, and manipulators.
Collaborate with hardware and applications teams to ensure system-level and PCB-level performance.
Work with Manufacturing and Supply Chain on vendor selection, part qualification, and cost optimization.
Document designs, changes, and engineering updates using standard processes.
