* 26 mars 2026 * 100% * Durée indéterminée * Rouges-Terres 61, 2068 Hauterive NE Focuslight Switzerland is one of the leading manufacturers of high-end micro-optics. We have more than 20 years of experience in the fields of optical design, micro manufacturing, and metrology. Our micro-optical components meet the highest requirements for applications in photolithography, optical networks, medicine, and metrology. To allow us to integrate last generation technology faster we are looking for a Optical Design Engineer Physical Optics We are looking for an experienced optical engineer that contributes to our activity in physical optics. As a subject matter expert in the corporate R&D team, you will work for the diffractive optics product range at Focuslight. This includes diffractive optical elements (DOEs), Metaoptics and all products where physical optics plays a major role in realizing a certain optical function. Your main task will be the optical design, tolerance analysis and product implementation of diffractive optical elements for industrial use. A solid background in electromagnetic simulation is required to use and further develop simulation tools for this purpose. To be successful, you need to gain a complete understanding of the laws involved in manufacturing miniaturized structures for optical use. Job Responsibility In more detail the Subject Matter Expert should : * Design, simulate and optimize micro-optical components based on physical optics principles * Develop and maintain simulation tools for optical design, tolerance analysis * Lead and mentor a team to oversee the DOEs production on different platforms and perform the functional test, ensuring products meet the customer-s specifications. * Efficiently coordinate the internal and external global resources to deliver the competitive DOEs in the market. * Capture and formalize learnings from rapid prototyping and iterative development cycles * Establish and maintain comprehensive technical documentation * Provide Technical support across the global teams and customers Key Competences * Excellent technical and analytical understanding of complex subjects * Habitude to work in project teams merging different competencies * Skilled in planning and executing experiments unifying different technology platforms * Connections within the etched optics industry and research institutes * Goal-oriented, self-driven, quick-responsive and accountable professional mindset Professional skills * B. Sc. / M. Sc./Ph. Degree in Microtechnology/Physics/Electrical Engineering or a related field * Strong expertise in electromagnetic theory and diffractive optics * Experience in metrology and characterization of micro and nanostructures * Fluent in English, German as well as French; Chinese is a plus * Highly experienced in optical system design and analysis of diffractive optics * Proficiency with optical modelling tools (VirtualLab, -) * Skilled in programming and numerical computing software tools (MatLab, Pyhton, -) * Knowing how to use computational hardware and AI for optical design optimization is a plus * Profound knowledge in micro and nanofabrication technology and clean room fabrication process, including DOE and Metaoptics wafer foundries We offer * A dynamic and flexible work environment with focus on work-life balance * A global and multicultural company culture Workplace: Focuslight Switzerland (2068 Hauterive/ Neuchâtel)
