Telecom Systems Software Engineer (5G RAN | ARM/x86)

We are a dynamic and rapidly growing company developing next-generation telecommunications technologies for global markets. Our mission is to shape the future of wireless by delivering cutting-edge 5G and 5G mmWave solutions. We're looking for a Telecom Systems Software Engineer to join our RAN team and play a key role in developing and maintaining the L1/L2/L3 protocol stack and enabling multi-platform support (x86 and ARM).

As a Telecom Systems Software Engineer, you will be responsible for maintaining and enhancing the software stack of our 5G Radio Access Network (RAN) solutions. This includes implementing new features across L1/L2/L3, optimizing the system for new architectures (ARM), and integrating licensing mechanisms. You’ll work with a multi-disciplinary team on real-time telecom solutions in a fast-paced, collaborative environment.
