We are now looking for a Senior Thermal Mechanical Photonic Designer. We are part of the global circuits team at NVIDIA that craft the state-of-the-art GPUs for all applications such as supercomputers, gaming consoles and self-driving cars. Come join us in our mission to Engineer the next generation of outstanding products. Teams are dedicated to the architecture and design of CMOS and Silicon-Photonics high-speed chip interfaces (NVLink, IEEE, PCIE, USB, OIF) and other sophisticated photonic functions. Strong hands-on lab experience with silicon evaluation, debugging, characterization, and bring up.

What you will be doing:

• Work on Thermal and Structural design of Silicon Photonic designs

• Run stress simulation in optical components and fiber alignment and propose improved design of optical components.

• Set up experimental methodology for thermal validation and laser performance under different stress conditions.

• 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

What we need to see:

• PhD in Electrical Engineering, Physics, or a similar discipline (or equivalent experience) with 5+ years of experience in a related field

• 3+ 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
