We seek a skilled Photonics Characterisation Engineer with a strong focus on experimental characterisation, testing, and measurements of novel photonic building blocks, including passive and electro-optical, nonlinear, and active components based on thin-film lithium niobate (TFLN). This key position demands creativity and technical expertise in the lab, including measurement automatisation and large dataset analysis. The ideal candidate will be at the forefront of developing our comprehensive process design kit (PDK) component library used by customers worldwide. You will also contribute to developing novel PIC circuits, ensuring top-tier performance and integration. This role involves close collaboration with our multidisciplinary teams, especially with the design and modelling team, as well as our process development and integration teams, to bring groundbreaking photonic solutions from concept to market.
