We seek a skilled Photonic Design Engineer with a strong focus on modelling, simulation, and optimising novel photonic and electro-optical systems and sub-systems based on thin-film lithium niobate (TFLN). The ideal candidate will contribute to developing our process design kit (PDK) component library and novel PIC circuits, ensuring top-tier performance and integration. This role involves close collaboration with our multidisciplinary teams, especially with experimental characterisation and process development, to bring groundbreaking photonic solutions from concept to market.
