Company

hirify.global develops photonic infrastructure for AI and high-performance computing data centers, including 3D-stacked photonics engines and optical interconnect products.

What you will do

• Design and maintain compact and behavioral models for active and passive silicon photonic elements.
• Model process variation, dispersion, thermal-optical behavior, nonlinear effects, and fabrication variability.
• Partner with device engineers to extract and calibrate parameters using optical solvers, foundry PDKs, and silicon data.
• Build sub-circuit simulations for Guide laser modules and Passage optical interconnect blocks.
• Optimize photonic and analog circuit topologies for loss, extinction ratio, isolation, tuning efficiency, bandwidth, and noise.
• Run corner, Monte Carlo, margin, and yield analyses, and validate models against production silicon measurements.

Requirements

• Ph.D. in Electrical Engineering, Applied Physics, Photonics, or a related discipline with 2+ years of industry experience, or an M.S. with 5+ years of experience.
• Deep knowledge of silicon photonic physics, analog circuit fundamentals, and behavioral component modeling for circuit-level co-simulation.
• Experience with Lumerical, RSoft, or Tidy3D and analog IC tools such as Cadence Virtuoso and Spectre.
• Strong Python skills for modeling, data extraction, and maintainable engineering code.
• Ability to solve complex technical problems through data-driven analysis and structured simulation automation.
• Ability to present technical information clearly in written and verbal form.

Nice to have

• Experience with microring modulators, filters, DWDM MUX/DEMUX structures, and thermal tuning.
• Experience with lasers, III-V photonics, SOAs, wavelength lockers, or heterogeneous integration.
• Analog front-end experience with TIAs, modulator drivers, heater drivers, or DACs.
• Experience with silicon photonics PDKs, process variation data, and laboratory measurement correlation.
• Publications or patents in photonic circuit design or modeling.
