Lightmatter Tech Stack
Photonic processors and optical interconnect hardware for data center computing
Lightmatter designs photonic computing engines and optical interconnect systems using hardware simulation (Tidy3D, SystemVerilog, Cadence) and embedded systems tools (OpenBMC, gRPC, Python). Active hiring is almost entirely staff-and-senior-level engineering (26 of 28 roles), pointing to a hardware-scale-up phase focused on control plane architecture, laser integration, and packaging for AI workloads—challenging technical work requiring depth rather than headcount.

You've provided the word "Passage" but this appears to be:
1. A generic English word (a corridor, text excerpt, etc.)
2. Not a standard technology product name
