Senior L1 Software Engineer – 5G/6G Baseband

We are seeking a highly skilled L1 Software Engineer to join Huawei’s Sweden Research Center in Stockholm and contribute to the

research, architecture, design, and implementation of next-generation wireless baseband systems.

In this role, you will work on advanced Layer 1 (Physical Layer) software technologies for future wireless RAN systems. You will

be responsible for translating advanced wireless algorithms into highly efficient real-time software implementations running on

heterogeneous baseband computing platforms, including DSPs, CPUs, ASIC accelerators, and other specialized processing

architectures.

You will collaborate closely with wireless algorithm researchers, SoC architects, DSP designers, compiler experts, and system

engineers to develop high-performance and energy-efficient Layer 1 solutions for next-generation wireless communication systems.

Your work will directly contribute to Huawei's future wireless baseband architecture, software platform, and product

competitiveness.

You will contribute to the design, development, optimization, and validation of high-performance Layer 1 software for

next-generation wireless RAN systems.

• Implement and optimize key PHY functions, including channel estimation, MIMO detection and precoding, beamforming, OFDM,

synchronization, LDPC/Polar coding, HARQ, and Massive MIMO processing.

• Optimize workloads using SIMD/vectorization, multi-core parallelism, pipeline optimization, memory/cache optimization, DMA, and

fixed-point techniques.

• Contribute to hardware/software partitioning and evaluation of new processor instructions, accelerators, and memory

architectures.

• Strong knowledge of 4G/5G NR Layer 1, OFDM, Massive MIMO, beamforming, channel estimation, MIMO processing, coding, HARQ, and

link adaptation.

• The candidates should have highly developed skills in finding new innovative solutions, strategic visions and ability of

leading and driving activities.
