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 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

What You Bring

Required

-

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

-

Solid understanding of integrated photonic building blocks, both passive and active, and their electrical drive requirements

-

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

Nice to have

-

Experience modelling signal propagation in photonic integrated circuits

-

Hands-on experience with silicon photonics platforms

-

Experience with optical/photonic simulation tools (e.g., FDTD, mode solvers, circuit-level simulators)

-

Familiarity with foundry PDK-based photonic design flows

-

Tcl scripting
