Photonic Component Modelling Engineer

<p style="min-height:1.5em"><strong>About Us</strong></p><p style="min-height:1.5em">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.</p><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>About the Role</strong></p><p style="min-height:1.5em">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.</p><p style="min-height:1.5em">You’ll need to understand how a component’s behavior shifts with its surrounding optical and electrical circuitry and with operating conditions.</p><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>What You’ll Do</strong></p><p style="min-height:1.5em">Working closely with the system verification, photonic design, and photonic characterization teams, you will:</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Develop and maintain models of optical primitives (modulators, switches, photodetectors, couplers, etc.) for simulation and system verification environments</p></li><li><p style="min-height:1.5em">Verify that models accurately represent device physics across process, voltage, and temperature (PVT) corners</p></li><li><p style="min-height:1.5em">Release models that pass defined QA criteria</p></li><li><p style="min-height:1.5em">Verify PDK component libraries so that PDK updates and process variations don’t break circuit-level simulations</p></li><li><p style="min-height:1.5em">Extract model parameters from lab measurements and work with characterization to correlate simulation with measurement</p></li><li><p style="min-height:1.5em">Build and maintain automated tooling (Python and/or MATLAB) for parameter extraction, model fitting, and regression tracking</p></li><li><p style="min-height:1.5em">Maintain regression suites so model and PDK changes are checked against reference data before release</p></li><li><p style="min-height:1.5em">Resolve model discrepancies found at system level and feed model-based design risks back to photonic design</p></li><li><p style="min-height:1.5em">Keep reproducible records: version-controlled models, scripts, reference data, and QA results</p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>What You Bring</strong></p><p style="min-height:1.5em"><em>Required</em></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">MS/PhD (or equivalent experience) in photonics, electrical engineering, applied physics, or a related field</p></li><li><p style="min-height:1.5em">3+ years of experience in photonic component design and/or simulation</p></li><li><p style="min-height:1.5em">Solid understanding of integrated photonic building blocks, both passive and active, and their electrica
