Senior Photonic Modeling Engineer for AI Optics

Salience Labs Ltd; Abingdon; On-site; GBP 70,000 - 100,000; Full time

Job summary

Salience Labs Ltd is seeking a Photonic Component Modelling Engineer to build and qualify behavioral and compact models that capture underlying device physics. Your models will underpin system-level verification for mixed photonic and electronic components.

You will collaborate with system verification, photonic design and characterization teams to develop models for modulators, switches and detectors; extract parameters from lab data; and maintain Python/MATLAB tooling and regression suites to

Qualifications

• MS/PhD (or equivalent experience) in photonics, electrical engineering, applied physics, or a related field.
• 3+ years of experience in photonic component design and/or simulation.
• Strong scripting ability (Python and/or MATLAB) for model fitting, data analysis, and simulation/measurement correlation.
• Comfortable working in Linux and with version-controlled repositories.
• Strong documentation habits, including model specifications, QA reports, and traceability from reference data to released models.
• Clear communication and a collaborative approach across disciplines.

Responsibilities

• 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 simulation with measurement.
• Build and maintain automated tooling (Python and/or MATLAB) for parameter extraction, model fitting, and regression tracking.
• Maintain regression suites so model and PDK changes are checked against reference data before release.
• Resolve model discrepancies found at system level and feed model-based design risks back to photonic design.
• Keep reproducible records: version-controlled models, scripts, reference data, and QA results.
