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:
- Strong experience in Layer‑1 / PHY firmware development:
- Hands‑on experience with LTE and/or 5G NR:
- Solid understanding of 3GPP PHY specifications:
- Strong C/C++ programming skills:
- Experience working on real‑time or embedded systems:
- Good understanding of:
- OFDM / SC‑FDMA
- Numerologies and frame structures
- HARQ and link adaptation

Nice to Have
- Experience with gNodeB / eNodeB PHY software:
- Exposure to FAPI / nFAPIor similar PHY‑MAC interfaces
- Experience with massive MIMO or beamforming:
- Knowledge of O‑RAN or split‑PHY architectures:
- Background in DSP or wireless signal processing:
- Experience with NB‑IoT, NTN, or advanced NR PHY features

Minimum Qualifications:
- Bachelor's degree in Engineering, Information Systems, Computer Science, or related field and 2+ years of Systems Engineering or related work experience.
