Summary of Role 

As a Packaging Engineer within GF’s Integrated Optics organization, you will lead the development and sustainment of advanced optical packaging solutions for silicon photonics (SiPh) and co-packaged optics (CPO) platforms. You will collaborate across photonics, electrical, mechanical, and manufacturing teams to deliver scalable, low-loss, and cost-effective packaging architectures that meet stringent performance and reliability targets.  

Essential Responsibilities include: 

• Own the definition, design, and qualification of optical packaging architectures for SiPh-based modules, including fiber attach, photonic die placement, and thermal/mechanical integration.  

• Develop and implement scalable fiber-to-chip coupling strategies (e.g., V-groove, passive alignment, lens integration) for high-density optical I/O.  

• Drive heterogeneous integration (HI) of photonic and electronic components using 2.5D/3D/3.5D packaging technologies (e.g., TSV, Cu-Cu hybrid bonding, advanced molded integration).  

• Perform multiphysics simulations (thermal, mechanical, optical) to optimize package performance and reliability.  

• Lead root cause analysis and corrective actions for yield and reliability issues using FMEA, DOE, and FA tools.  

• Collaborate with OSATs and internal manufacturing teams to ensure mass production readiness and process transfer.  

• Support cost modeling and drive package cost reduction initiatives aligned with GF’s B2B supply chain strategy.  

• Present technical updates and roadmaps to internal stakeholders and external partners.  

Other Responsibilities 

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

• Travel up to 25% to other GlobalFoundries facilities or external partner sites may be necessary. 

Required Qualifications 

• Master’s degree or higher in Packaging, Materials Science, Mechanical Engineering, Optical Engineering or related field.  

• 8+ years of experience in semiconductor packaging, with a focus on photonic or advanced packaging.  

• Hands-on experience with fiber attach processes, photonic alignment, and optical coupling techniques.  

• Familiarity with packaging technologies such as die attach, flip-chip, underfill, molding, and micro-optics integration.  

• Understanding of reliability standards and qualification methodologies for optical modules.  

• Excellent analytical, problem-solving, and communication skills.  

• Experience in bringing packaged products from development into production.  

• Strong written and spoken English communication skills.  

Preferred Qualifications 

• Experience with automated optical/electro-optical test setups and motion control systems (e.g., Python-based).  

• Knowledge of co-packaged optics (CPO), pluggable modules, and silicon photonics ecosystems.  

• Expertise in chip package interaction for 2D, 2.5D, 3D, 3.5D SiPh advanced packaging. 

• Strong background in thermal/mechanical modeling and optical simulation tools (e.g., Lumerical, COMSOL).  

• Familiarity with GF’s Fotonix™ platform, including 300mm monolithic SiPh integration and advanced packaging flows.  

• Experience working with OSATs and managing external development partners.  

• Demonstrated ability to lead cross-functional teams and influence technical direction.
