- Produce complete technical quotes for optics/coatings.
- Advise customers on coating design/substrate choices.
- Liaise closely with production, process engineers, and metrology to ensure specs are achievable and to set test procedures and acceptance flows.
- Review and approve incoming/outgoing technical documentation (spec sheets, coating maps, inspection reports).
- Support occasional trade shows and customer visits (travel <10%).
Required qualifications:
- PhD in physics, optics, engineering, or closely related field — strongly preferred; exceptional M.S. engineering candidates with relevant experience considered.
- Hands-on experience using optical cavities for physics.
- Direct, practical familiarity with vacuum systems and thin-film deposition.
- Excellent interpersonal skills for technical customer interactions internal coordination.
Preferred / nice-to-have:
- Experience modeling coating stacks (optical thin-film design tools).
