GreenWave™ Radios Tech Stack

Open RAN silicon and firmware for power-efficient 5G base stations

Semiconductor Manufacturing San Diego, CA 51–200 employees Founded 2013 Privately Held

GreenWave Radios designs RF system-on-chip (SoC) and embedded firmware for Open RAN cellular base stations, with a focus on reducing power consumption and operational cost in 5G infrastructure. The tech stack—ARM, C/C++, Embedded Linux, Yocto, Xilinx, plus RF design tools (Keysight ADS, Cadence AWR)—reflects a hardware-firmware co-design operation. Hiring velocity is decelerating while seniority skews toward senior engineers and leads, suggesting a product-focused consolidation phase rather than team expansion.
