Thorlabs is seeking an experienced optical coating engineer. Job activities include new process/product development, new equipment introduction, process improvement, equipment improvement, process maintenance, equipment maintenance, lean manufacturing projects, and maintaining fab documentation. This position requires deep knowledge of optical coating processes, process engineering core skills, equipment trouble-shooting skills, and a track record of using data-driven problem solving techniques (e.g. Six Sigma methods). Preference will be given to experienced candidates with a broad range of optical coating experience.

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

  • Provides state of the art coating designs from UV to Mid-IR both transmission and reflection.
  • Ability to utilize all formats of material deposition: E-beam ,IAD, Magnetron Sputtering.
  • Ability to design coating tooling for precision optics and fiber.
  • Introduce new product, process, equipment and material technologies into optical coating fab in timely manner, using effective design input, evaluation testing, and project management.
  • Utilize continuous improvement tools, project management skills, team leadership, and basic engineering skills to 1) reduce manufacturing costs, 2) improve/sustain tight control of wafer fab manufacturing process.
