Senior Etch Process Engineer

The position will be a subject matter expert on etched optics at the corporate research and development level. The Senior Etch Process Engineer will lead hands-on development and manufacturing of high-performance etched optics within state-of-the-art cleanroom facilities. The candidate will participate in and has the opportunity to 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.

Job Responsibilities

In more detail the Senior Etch Process 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.
• Build and manage a new product pilot line bridging R&D development and production.

Key Competences

• Have the ideas, methodology, and ownership needed to build the team and capabilities to become the best in etched-optics production.
• Have a “fail fast, fail cheap” mindset to quickly identify the optimal solution.
• Goal-oriented and self-driven, with a strong sense of commitment and accountability.
• Proactive and innovative mindset, consistently seeking improvements and new solutions.
• Excellent technical and analytical skills, with the ability to understand and solve complex problems.
• Experienced in collaborative project environments, integrating diverse competencies.
• Capable of planning and executing experiments that combine multiple technology platforms.

Professional Skills

• Sc., M.Sc., or Ph.D. in Microtechnology, Physics, Optics, Electrical Engineering, or related fields.
• Practical industrial experience in the microfabrication of etched silicon and fused silica lenses, with required expertise in dry etching and photolithography.
• In-depth theoretical knowledge of micro- and nanofabrication technologies.
• Proficiency in metrology and characterization techniques for micro- and nanostructures.
• Basic understanding of optics and photonics.
• Experience in solving problems in dry-etching, such as eliminating etch pits and deterministically controlling etched surface shape.
• Experience in high-volume production with optics, CMOS, or MEMS industry.
• Experience in monitoring and controlling etch selectivity and etch rate is an advantage.
• Familiarity with industrial quality standards such as ISO 9001 and ISO 10110 is a plus.
• Fluency in English is required; proficiency in French and German is considered as an asset.

We Offer

• A dynamic and flexible work environment with focus on work-life balance.
• A global and multicultural company culture.
• A key role in leading and driving the development of etched optics, with clear career growth opportunities toward becoming an influential leader at Focuslight.
