Job Responsibilities
The position will be a subject matter expert on etched optics at the corporate research and development level. The Senior Process Integration Engineer will lead hands-on development and manufacturing of high-performance etched optics within state-of-the-art cleanroom facilities. She/He will take ownership of establishing a new pilot product line, contribute to strategic R&D initiatives, and strengthen Focuslight’s etched optics capabilities to expand and enhance the company’s product portfolio. One main task here is to transform conceptual optical designs into functional, manufacturable products by advancing the etch optics processing capabilities, while implementing robust quality control measures throughout the process. This role offers a unique opportunity to grow into an influential leader at Focuslight by strengthening Focuslight’s competitiveness in the global etched optics market.
In more detail the Process Integration Engineer should,
- Lead the development and fabrication of high-end etched optics products on the pilot production line.
- Design, develop, and validate process flows tailored to optical product requirements, ensuring manufacturability and performance.
- Drive the full product lifecycle—from conceptual optical design to functional product.
- Work with the production team as one team to resolve process issues in mass production and implement new processing capabilities developed on the pilot line to improve product optical performance or reduce production costs.
- Strategically leverage global internal and external resources to deliver competitive optical solutions in a fast-paced market, with a strong focus on rapid and successful execution.
- Create and maintain comprehensive technical documentation to support process development, product qualification, and knowledge transfer.
- Provide hands-on support for R&D activities in Focuslight’s cleanroom facility in Hauterive, contributing to innovation and continuous improvement.
