Summary of Role: GlobalFoundries is seeking an experienced thermal, mechanical, and/or electrical modeler/engineer with demonstrated cryogenic modeling experience to support cryogenic packaging and system co-optimization R&D. The engineer will leverage commercial multi-physics tools to build, correlate, and apply models that capture low-temperature material property behavior and thermo-mechanical effects (e.g., thermal contraction and CTE mismatch) to guide device, integration, and cryogenic 3DHI advanced packaging optimizations for mechanical, thermal, and/or electrical performance. 

Essential Responsibilities:  

• Demonstrated experience using commercial software to develop and correlate cryogenic thermal, mechanical, and/or electrical models for semiconductor devices and advanced packages (e.g., 77 K and below), including temperature-dependent material properties and boundary conditions. 

• Stress simulations for continuous and discontinuous active areas, and how stress affects device performance if the skill is mechanical modeling.  

• Anticipate integration/process issues, based on provided information from integration, process or design enablement teams and performed modeling.  

• Facilitate discussion with originating team to identify simulations that highlight critical process interactions and drive optimal 3DHI technology decisions. 

• Apply commercial simulation software to mimic cryogenic semiconductor process flows and highlight the areas of concern. 

• Extensive interaction with integration, device, and design engineers to assure development of a working technology.  

Other Responsibilities:  

• Perform all activities in a safe and responsible manner and support all Environmental, Health, Safety & Security requirements and programs.  

• Other duties as assigned by manager. 

Required Qualifications:  

• M.S. + minimum of 10 years of relevant experience. 

• Semiconductor mechanical, thermal and/or electrical simulation tool experience with Ansys Mechanical Workbench or other applicable software for any of those 3 modeling applications. 

• Strong problem solving and technical trouble shooting skills including expertise in design of experiment. 

• Must have at least an overall 3.0 GPA and proven good academic standing. 

• Language Fluency - English (Written & Verbal). 

• Solid understanding of semiconductor processes and integration techniques. 

• Good computer / software skills. 

• Ability to clearly present results to small and large groups.  

• Travel - Up to 10%. 

Preferred Qualifications:   

• PhD + 8 years of relevant experience. 

• Thermal and electrical simulation for specific IC circuit designs (RF analog experience preferred) and with LVS and DRC verification tools (Cadence / Mentors Graphics / Keysight ADS…).   

• Demonstrated work performance in an environment requiring a high level of attention to detail and timeliness. 

• Demonstrated prior leadership experience in the workplace, school projects, competitions, etc.  

• Project management skills, i.e. the ability to innovate and execute solutions that matter; the ability to navigate ambiguity. 

• Strong written and verbal communication skills. 

• Strong planning & organizational skills.
