Senior Silicon Photonics Design Engineer

Requirements:

• MS and/or PhD in Electrical Engineering, Applied Physics, Photonics/Optical Engineering, or related field (or equivalent experience).
• Electronic-photonic co-simulation and Verilog-A compact modeling, integrating photonic models into a circuit design environment (Cadence ecosystem a plus).
• 5+ years of design experience in industry or applied R&D, spanning photonic and/or high-speed electronic design.
• Proven track record in silicon photonics device modeling, compact modeling, or optical component design.
• Photonic simulation tools: Lumerical (FDTD, MODE, INTERCONNECT, CHARGE) or comparable (Ansys, Synopsys OptoDesigner/RSoft).
• Solid grasp of photonic device physics: resonator theory (CMT, Q, FSR, ER/OMA), carrier-based and thermo-optic modulation, waveguide loss and dispersion.
• Experience building verification/testbench environments and correlating models to measurement.
• Strong debugging and analytical skills, and a genuine desire to work as part of a close-knit team.

Nice to Haves:

• Foundry PDK flow experience, photonic layout/DRC awareness, optical VNA/LCA measurement background.

What you'll be doing:

• Develop and maintain the electro-optic co-simulation flow, integrating Verilog-A compact models with circuit and link simulation so photonics and electronics can be verified in one environment.
• Define silicon-photonics test structures and characterization plans, and extracting compact-model parameters from measured optical, electrical, electro-optic, RF, and thermal data.
• Build and calibrate compact/behavioral models for silicon photonic components — ring modulators and resonators, Mach-Zehnder modulators, photodetectors, grating/edge couplers, waveguides, splitters, and thermo-optic phase shifters.
• Correlate models against foundry and in-house characterization data (spectra, S-parameters, OMA/ER), contributing to the model accuracy and validation the team is collectively responsible for.
• Partner closely with circuit/SerDes designers, system teams, and foundry contacts as the direct customers of the team's models.
• Contribute to the shared component library the team maintains — versioning, documentation, QA, and release — taking detailed physics/EM models as source data and abstracting them into design-usable form.
