Teams at Lightmatter

Designs and maintains automated hardware test software for photonic chips across bench-top, wafer, and automated test equipment environments. Responsibilities include developing test methods and flows, controlling instruments, integrating probers and embedded systems, building data pipelines, debugging hardware/software interactions, supporting releases, and collaborating with hardware, characterization, and manufacturing teams. The role also involves test architecture ownership, mentoring engineers, and hands-on laboratory work.

Designs and validates end-to-end electro-optic systems for high-volume photonics products. Responsibilities include system modeling with Cadence, VPI Photonics, and Keysight ADS; co-designing silicon photonic devices; developing high-speed RF experiments; testing optical modulators and receivers; analyzing performance, power, and production requirements; and collaborating with electronics and photonics engineering teams.

Own end-to-end simulation, co-design, and laboratory verification of photonic-electronic links. Develop multi-physics optical and analog models, perform corner, Monte Carlo, and PVT analyses, create link budgets, and correlate simulations with silicon measurements. Partner with photonic and analog circuit teams on architecture, specifications, interface requirements, and corrective design actions. The role requires high-speed optical lab expertise, silicon photonics experience, and proficiency in photonic, mixed-signal, and Python-based simulation workflows.
