Senior Optical Scientist

Role Summary:

• Develop and apply ray-tracing, wave-optics, and analytical models to design and optimize fiber-optic connectors and waveguides.
• Use simulation results to explain the underlying physical mechanisms and support prototype development.

Key Responsibilities:

• Design, model, and analyze fiber-optic connectors and fiber-to-chip interfaces.
• Calculate and analyze optical modes in fibers and waveguides, and model light propagation and coupling between fibers, waveguides, and photonic chips.
• Perform sensitivity, tolerance, and Monte Carlo analyses to predict coupling efficiency, insertion loss, and performance statistics.
• Optimize designs for optical performance and turn simulation results into design rules and specifications that support prototype fabrication.
• Compare simulation results with measurement data and support root-cause analysis of discrepancies and performance issues.
• Contribute to other optical modeling tasks as needed, such as diffraction gratings, surface light scattering, illumination systems, and light propagation in birefringent and gradient-index materials.
• Document and communicate technical work through reports and presentations, and contribute to invention disclosures and patent applications where appropriate.
• Occasional travel may be required.

Required Skills:

• Ph.D or Master's degree in Physics, Applied Physics, Optics, Photonics, Optical Engineering, or a related technical field, plus relevant experience; equivalent combinations of education and experience may be considered.
• Strong knowledge of fiber and integrated optics: optical fibers, waveguides, optical modes, mode coupling, and mode-field matching.
• Hands-on experience with Zemax OpticStudio in both sequential and non-sequential modes, including physical optics propagation.
• Experience with wave-optics modeling methods (e.g., FEM mode solving, FDTD, or BPM) using commercial or in-house tools.
• Experience with tolerance, sensitivity, and Monte Carlo statistical analysis of optical systems.
• Proficiency in Python for scripting, automation, and data analysis.
• A strong sense of ownership and the ability to deliver results with limited supervision.
• Strong analytical and problem-solving skills, with the ability to troubleshoot complex technical challenges.
• Excellent communication and interpersonal skills for working with globally distributed team members.

Desired Skills:

• Ph.D. in Physics, Applied Physics, Optics, Photonics, Optical Engineering, or a related discipline.
• Familiarity with telecommunications, optical connectivity, co-packaged optics, and data center and AI interconnect architectures.
• Hands-on experience with RSoft (FemSIM, FullWAVE, BeamPROP) and/or Ansys Lumerical (MODE, FDTD).
• Understanding of optical experiments and measurement techniques, and experience comparing simulations with measurement data.
• Experience with structural-thermal-optical performance (STOP) analysis, e.g., importing FEA deformations into optical models.
• Experience with COMSOL Multiphysics and/or MATLAB.
• Experience with LightTools or other illumination design software.
• Basic knowledge of machine learning and optimization methods.
