- Implement and optimize signal processing algorithms such as channel estimation and equalization, HARQ processing, MIMO and beamforming.
- Work on FEC processing including Turbo coding/decoding (LTE) and LDPC and Polar coding/decoding (5G NR).
- Optimize real-time performance for latency and throughput.
- Integrate PHY software with MAC, RF, and hardware platforms.
- Debug complex PHY-level and real-time issues.
Krav
- 5-8 years of 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.
Önskade kvalifikationer
- Experience with gNodeB / eNodeB PHY software.
- Exposure to FAPI / nFAPI or 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.
Förmåner
- Work on cutting-edge 5G NR technology.
- Build performance-critical PHY software used in real networks.
- Collaborate with highly experienced wireless and systems engineers.
- Opportunity to work on next-generation RAN architectures.
