Top Tech Jobs & Startup Jobs in Boston, MA

Lead development of the internal photonics PDK and component library. Build Python-based pcells, create and validate compact models for active and passive devices, automate parameter extraction from electromagnetic solvers, and correlate models with lab measurements. Implement regression testing, CI pipelines, and robust netlist/connectivity logic to ensure layout, models, and simulations remain synchronized.

The Staff Mechanical Engineer will focus on mechanical design, structural analysis, GD&T, and FEA to enhance packaging technologies for AI architectures at Lightmatter.

The Photonics Technical Lead will create scalable laser solutions for silicon photonics AI communications, collaborating across teams to ensure design feasibility and meet performance specifications.

The Staff Electrical Test Engineer will develop and implement ATE test solutions for Silicon Photonics products, support manufacturing testing, collaborate with teams to debug failures, and enhance testing productivity with scripting.

Design, layout, simulate, and test silicon photonic devices (couplers, muxes, rings, switches) and integrated laser systems. Collaborate with packaging, systems, and characterization teams to validate devices, troubleshoot performance, and optimize designs for manufacturability. Publish results and support product integration.

Lead design verification for integrated digital, analog, and photonic devices using UVM, mixed-signal/AMS methods, RNM, and emulation. Define DV methodology, create reusable testbenches, run block and full-chip verification, integrate analog IP and behavioral models, close coverage and signoff, and collaborate with architects and designers for performance and post-silicon validation.

The Sr./Principal Mixed-Signal Digital Architect will design digital circuits for photonic-based communication, collaborate with teams, and lead product development.

Design analog and mixed-signal circuits for optical communication systems, collaborate with architects, and validate circuit performance in the lab.
