- Modeling Si die-package thermo-mechanical interactions
- Solder joint fatigue and creep modeling
- Support the optical engineering and system engineering leads with the opto-mechanical system design
- Die-package thermo-mechanical interactions in electronic packages for predicting failures during various assembly and reliability tests to recommend design, process or material changes
- Hygroscopic stresses in electronic packages due to moisture diffusion
- Crack propagation and interfacial delamination
- Multifaceted simulation of wire-bonding and wire fusing process
- Thermal characterization of electronic packages (crafting thermal specification datasheets based on FE and experiments according to JEDEC standards)
- Solder joint fatigue and creep modeling
Qualifications
- PhD in Electrical Engineering, Physics, or a similar discipline (or equivalent experience) with 15+ years of experience in a related field
- 8+ years of experience in the development of silicon photonics ICs from concept to high-volume manufacturing
- Experience in product development of optics or photonic systems
- Experience in applied research on Silicon Photonic ICs and Systems
- Hands-on experience with Silicon Photonics products
- Proficient in Ansys tools
- Background with design tools and fixtures to aid in alignment, fabrication, gluing, and assembly of lasers, interferometers, and optical components
- Experience working, communicating, and collaborating in a cross-functional team environment
- Experience defining system performance and component specifications
- Excellent verbal and written communication skills
- Self-motivated and self-directed individual, with little supervision vital
