Lumentum Tech Stack

Optical and photonic components for data center and telecom infrastructure

Telecommunications San Jose, California 10,001+ employees Founded 2015 Public Company

Lumentum manufactures lasers, modules, and optical subsystems at scale—a capital-intensive, process-driven business where yield and cycle-time directly impact margin. The tech stack reflects hardware-software integration (VHDL, Verilog, SystemVerilog, MATLAB, LabVIEW, HFSS for design; Docker, gRPC, Python for production systems) and the hiring skew is heavily toward engineering and manufacturing (244 of 314 open roles), with a backlog of device reliability, yield improvement, and test automation projects. Recent adoption of ChatGPT and FPGA/CPLD tooling suggests exploration of AI-assisted design and flexible hardware solutions.
