Lead verification and characterization of high-speed electro-optic links across silicon and system programs. Responsibilities include lab debugging, electrical and optical channel modeling, link-budget ownership, eye-diagram and BER analysis, silicon bring-up, signal-integrity root-cause investigations, architecture tradeoff guidance, automation development, and engineering mentorship. The role requires deep expertise in high-speed SerDes, photonics, measurement systems, and modeling tools.

Drive the micro-architecture of a photonic communication fabric. Propose photonic device designs, estimate performance/power/area, collaborate with analog and photonic engineers, and author and validate architectural specifications for Passage.

Leads system-level electrical design for silicon photonics AI accelerators and interconnect products. Responsibilities include defining hardware requirements, designing power, memory, and high-speed circuits, selecting components, overseeing PCB layouts, validating boards in the lab, ensuring manufacturability, integrating cross-functional systems, and supporting contract manufacturing. The role requires taking products from concept through production and collaborating with mechanical, software, IC, packaging, and supply partners.

Design and model silicon photonic and analog sub-circuits for laser products and optical interconnects. Build compact and behavioral models incorporating fabrication variability, dispersion, thermal effects, and nonlinear properties. Calibrate models using optical solvers, PDKs, and silicon measurements; develop circuit simulations for lasers, modulators, filters, receivers, and controls. Perform corner, Monte Carlo, margin, and yield analyses, and validate models against production silicon data.

Develop and maintain photonics Process Design Kits, including Python-based layout libraries, compact behavioral models, test structures, and automated verification pipelines. Validate models against silicon measurements through data fitting and statistical analysis. Collaborate with multidisciplinary engineering teams to support large-scale photonic integrated circuit tape-outs. The role requires advanced photonic device physics, circuit simulation, Python programming, layout automation, and experience with foundry PDKs and design verification.

Lead product definition, positioning, partnerships, customer design wins, rollouts, pricing, forecasting, and lifecycle management for silicon photonics products. The role focuses on Lightmatter’s Passage interconnect platform, evaluation systems, and photonics-enabled data center solutions, collaborating across engineering, sales, operations, finance, customers, and executives from early development through volume production and end-of-life.

Own the architecture and development of firmware test automation frameworks, hardware-in-the-loop infrastructure, CI/CD integration, diagnostics, telemetry, and test reporting for photonic hardware. Debug failures across firmware, boards, instruments, fixtures, and test software. Define test strategies, improve framework reliability, participate in design reviews, integrate embedded management interfaces, and mentor engineers. The role requires strong Python, embedded C/C++, CI/CD, hardware testing, and automation architecture experience.

Lead verification and characterization of high-speed electro-optic links across silicon and system programs. Perform lab measurements, model electrical and optical channels, own link budgets and verification methodology, and debug signal integrity issues involving eye diagrams, BER, jitter, equalization, and channel impairments. Support silicon bring-up, influence architecture decisions, develop automation tools, and mentor engineers.

Lead hardware bring-up and automated system-level testing for photonic IC products from evaluation through high-volume manufacturing. Responsibilities include ATE hardware integration, electrical bring-up, supplier debugging, test software development in Python or C/C++, power-sequence validation, protocol testing, firmware diagnostic integration, and lab instrumentation control. The role collaborates with IC design, DFT, and firmware teams to isolate silicon and board-level issues.

Drives hardware systems program execution across electrical, mechanical, and systems engineering from design through production. Owns integrated schedules, resource planning, dependencies, material flow, supplier coordination, budgets, risks, and cross-functional communication. Coordinates with contract manufacturers, PCB fabricators, assembly houses, supply chain, finance, engineering teams, and executives while establishing lightweight program management processes in a fast-changing environment.
