Job Area:Engineering Group, Engineering Group > Systems Engineering

General Summary:
We are hiring a Layer‑1 (Physical Layer) Firmware Engineerto work on 5G NR gNodeB Firmware. This role focuses on PHY development on the DU side, building high‑performance, real‑time wireless software used in up-to-date cellular networks.

You will work closely with PHY, RF, platform, and system teams to develop and optimize carrier‑grade NR PHY features.

What You’ll Do
Develop and maintain Layer‑1 (PHY) firmwarefor 5G NR gNodeB:
Work on uplink and downlink PHY channels, including:
PUSCH, PDSCH, PUCCH, PDCCH, PRACH, SRS, SSB
Implement and optimize signal processing algorithmssuch as:
Channel estimation and equalization
HARQ processing
MIMO and beamforming
Work on FEC processing:
Turbo coding/decoding (LTE)
LDPC and Polar coding/decoding (5G NR)
Optimize real‑time performancefor latency and throughput
Integrate PHY software with MAC, RF, and hardware platforms
Debug complex PHY‑level and real‑time issues

What We’re Looking For





Required Skills:
