Telecommunications San Jose, California 1,001–5,000 employees Public Company

Harmonic supplies video delivery and broadband access hardware and software to cable and telecom operators. The engineering-heavy hiring mix (24 of 35 open roles) paired with active projects around Remote OLT, DOCSIS 4.0, and ONU interoperability testing reflects their focus on next-generation access standards. Pain-point concentration on interoperability gaps and network stability suggests they're working through fragmentation challenges as operators scale gigabit and fiber deployments.
