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 process, voltage, and temperature (PVT) corners Release models that pass defined QA criteria Verify PDK component libraries so that PDK updates and process variations don’t break circuit-level simulations Extract model parameters from lab measurements and work with characterization to correlate simula
