pSemi, A Murata Company Tech Stack

RF and power management semiconductors for mobile, IoT, and automotive

Semiconductor Manufacturing San Diego, CA 501–1,000 employees Founded 1990 Privately Held

pSemi designs integrated semiconductors across RF, power management, and antenna tuning for smartphones, base stations, and IoT devices under Murata ownership. The tech stack reveals a dual focus: simulation and validation tools (MATLAB, HFSS, Cadence) dominate the design phase, while Python, LabVIEW, and TestStand automation address a core pain point—lab throughput and yield characterization. Heavy intern hiring (12 of 26 open roles) signals either a scaling engineering operation or a seasonal ramp tied to prototype cycles.
