Digital Signal Processing (DSP) Engineer

Beamlink•Los Angeles, CA

176d•Hybrid

About The Position

Half the world still doesn't have stable Internet – want to play a critical role in changing that? Beamlink builds entire cellular networks in a matter of weeks, not years. These are built of easy-to-set-up cells, called Bentocells, which address the historic bottleneck preventing carriers from expanding beyond cities. Our dynamic engineering team designs these in-house along with the firmware, software, and network architectures that make them run. We are looking for a Digital Signal Processing Engineer to join our team full-time. You will work on high-speed digital systems, FPGA development, and software-defined radio (SDR) platforms powering Beamlink’s wireless networking products. This role involves designing complex digital hardware, developing FPGA-based packet processing systems, and improving signal integrity and RF system performance for next-generation telecommunications infrastructure.
