Senior Physical Optics Engineer | Thorlabs

This senior position requires an individual with Physical Optics and Optical Simulation experience. Responsibilities include designing, analyzing, and modeling optical systems that employ lenses, diffractive elements, and or, metasuraces and metamaterials. The engineer will be responsible for managing projects from concept to finished products. Although the location of the position is in Newton, NJ, from time to time it may be required to undertake duties at other facilities or Thorlabs locations.

Essential Job Functions include the following, but are not limited to:

  • Design products for manufacturability which utilize physical optics and sub-wavelength scale surface features for manipulation of light in novel ways. Analysis may include Rigorous Coupled Wave or Finite Difference Time Domain.
  • Model novel optical systems using Lumerical or COMSOL Multiphysics Simulation Software, as well as other optical design packages such as Zemax, CodeV or OSLO.
  • Review market, fabrication capabilities, and other applicable sources to determine requirements and/or feasibility of components. Communicate with industry to understand and define their needs.
  • Prepare technical data such as qualification test procedures, acceptance test procedures, reports, component maintenance manuals, etc.
  • Acts as technical expert for the company for both internal and external customers.
  • Keep current with newest applications, products, and manufacturing techniques within the industry. Share, discuss, and collaborate while looking for opportunities to implement.
