Hiring · 14 open jobsGeneral information
SirenOpt makes sensors and software for manufacturing nanoscale materials used in semiconductors, electronics, batteries, and aerospace. Its real-time manufacturing intelligence platform uses cold atmospheric plasma and physics-informed machine learning to help make thin films more cheaply. SirenOpt is based in San Leandro, California.
SirenOpt was founded in 2022 as a spin-out from the UC Berkeley Chemical Engineering Department. That academic root means the technology is fairly new, built for industries like chipmaking and batteries that are scaling up fast. SirenOpt is an H-1B sponsor.1
