Job Description:

This cross-disciplinary position supports all aspects in the development, fabrication, characterization, and application of semiconductor supermirrors produced at Thorlabs Crystalline Solutions in Santa Barbara, CA. Primary responsibilities include the operation, maintenance, and continued improvement of in-house microscopy-based inspection capabilities for optical characterization of production- and research-grade mirrors; realizing improved production processes by designing, executing, and interpreting quantitative test procedures in the cleanroom and in post-process inspection; development of automated measurement solutions to support such efforts; and compiling test reports and quality control data produced along the way for presentation to the wider group. This position involves working with a small multi-disciplinary team of scientists and engineers including mechanical and materials engineers, process technicians, and physicists.


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

  • Operate and maintain in-house metrology tools for the inspection of precision optics and optical materials, including optimization of various imaging modes and interferometric systems in the visible and near infrared spectral regions
  • Develop and support software and automation solutions for the inspection of coating batches, as well as large-area coatings, to inform production process improvements
  • Hands-on work in the nanofab (involving lithography, wet etching, solvent-based cleaning, plasma activation, etc.) with a focus on investigating and defining potential manufacturing improvements for increased production yields
  • Provide and maintain an in-house suite of software solutions at the lab-deployable level to support TCS-wide test and measurement needs
  • Perform and evaluate efficacy of process changes for improving production yields
  • Perform optical inspection of materials, including optical substrates and epitaxial material
  • Assist with fabrication of crystalline coatings as demand dictates
  • Assist with departmental functions such as shipping and receiving, inventory control, data and documentation maintenance, as well as laboratory organization




  • 1+ years of experience in software development for limited multi-user deployment and support required
  • 1+ years of experience in microfabrication techniques and familiarity with common tools in the field.



  • BSc. or higher in Experimental or Applied Physics, or related field such as Chemical / Electrical / Mechanical Engineering, or Materials Science


Specialized Knowledge and Skills:

  • Strong knowledge of building instrument control interfaces using Python, C, and/or C++
  • Knowledge and familiarity with microfabrication techniques and tools
  • Strong ability to work well in a group atmosphere and comply with high quality standards
  • Capability to shift from one task to another to address changing priorities
  • Experience with imaging systems will be advantageous
  • Experience with programming microcontrollers and FPGAs will be advantageous
