Modem DSP Engineer

AnySignal  · Los Angeles, CA  · Jan 25, 2025

AnySignal is a startup whose mission is to usher in the next generation of RF products and services. For the most demanding space and defense missions, AnySignal provides a flexible platform with world-class performance that is easy to deploy, monitor, purchase, and upgrade. Our team has a diverse range of backgrounds that cover cloud computing to artificial intelligence, communications and sensing, embedded systems, and much more. In an increasingly congested spectrum, there is a dire need to squeeze maximal capacity out of a space link. In the modern battlefield, waveforms are evolving on a weekly basis. As a Modem DSP Engineer, you will be responsible for the design and integration of signal processing algorithms spanning a multitude of communications systems. You will work side-by-side with FPGA, Software, Hardware, and Test counterparts to rapidly develop, deploy, and iterate upon algorithms for waveforms spanning a multitude of channels and environments. If you live and breathe DSP, and are seeking the freedom to build novel waveforms at breakneck speed and rapidly see them in action, this role is for you. In order to comply with the space technology export rules of the U.S. Government, such as the International Traffic in Arms Regulations (ITAR), it is necessary to be a U.S. citizen, a lawful U.S. permanent resident, a protected individual as specified by 8 U.S.C. 1324b(a)(3), or possess eligibility to secure the necessary authorizations from the U.S. Department of State. For additional information on ITAR, please seek further details. AnySignal values and fosters an...

Responsibilities:
Own the lifetime of DSP algorithms, from initial analysis to modeling to FPGA implementation to field deployment
Develop floating and fixed-point modeling infrastructure in MATLAB/Python/C++ to foster efficient algorithm development and implementation
