# Photonic Component Modelling Engineer

About Us Salience Labs is building an industry-defining approach to optical circuit switching for AI infrastructure, engineered for real latency reduction and cost savings. We’re moving towards real-world deployment, and joining at this stage means genuine ownership over that next chapter, working alongside a highly technical team on one of the most consequential problems in AI infrastructure today. About the Role We’re looking for a Photonic Component Modelling Engineer to build and qualify behavioral and compact models that accurately capture the underlying device physics. Your models will be the foundation for system-level verification of systems that combine photonic and electronic components. You’ll need to understand how a component’s behavior shifts with its surrounding optical and electrical circuitry and with operating conditions. What You’ll Do Working closely with the system verification, photonic design, and photonic characterization teams, you will: Develop and maintain models of optical primitives (modulators, switches, photodetectors, couplers, etc.) for simulation and system verification environments Verify that models accurately represent device physics across pro
