Lumentum is an industry leader in photonics technology.

The Silicon Photonics Design Engineer is a key member of a team of researchers responsible for the design of silicon photonics chips for cloud and network applications especially for the rapidly growing AI market.  You will work in a team environment to develop silicon photonics chips and components through conception, modeling, design, layout, and performance evaluation with a goal of feeding chip solutions directly into Lumentum products that are produced in large volume to meet market requirements.

Responsibilities:

  • Complete simulations of chip components to continuously improve and optimize performance to maintain Lumentum’s leading edge and to find novel solutions for next generation products
  • Work collaboratively with packaging teams and other teams to ensure that chip solutions meet all constraints for target applications.
  • With a clear understanding of the fabrication process, ensure that designs are kept within manufacturing tolerances.
  • Participate in the construction of chip-test stations, providing support with mechanical and software requirements, and conduct initial experimental measurements before transferring routine testing to other teams.
  • Evaluate performance results for typical performance behavior and for yield margin in a cost-effective high-volume manufacturing environment.
  • Communicate with team members.  Engage with others to both learn and teach.

Qualifications:

  • A PhD in Electrical Engineering or Physics or equivalent combination of education and work experience along with a solid background in optical physics and photonics
  • Strong background in photonic device modeling and analysis of test results
  • Experience with test methods used to characterize photonic chips
  • Expertise in software development to run experiments and/or to script simulations
  • Demonstrated drive and aptitude for research and development
  • Excellent oral and written English communication and presentation skills
  • Self-motivated, with strong analytical and problem-solving skills

Desired Qualities:

  • Proficiency with photonics simulation techniques such as FDTD, EME, etc. and software platforms that implement such techniques (e.g., Lumerical, Synopsys)
  • Proficiency with physical layout and verification software
  • Proficiency with statistical analysis software (SAS JMP)
  • Experience with fabrication of silicon photonics chips

Pay Range:

P40-USA-1 :$85,000.00 - $121,400.00
