Job Description
C++ Software Developer
IS-Wireless
• Design, implement, and optimize 5G NR Layer 1 (PHY) components in modern C++ for low-latency, high-throughput processing. • Build and tune signal-processing blocks (OFDM modulation/demodulation, channel estimation, equalization, synchronization, MIMO/beamforming, HARQ, LDPC/Polar). • Apply multithreading, lock-free techniques, fixed-point arithmetic, and SIMD (SSE/AVX/NEON) vectorization to meet real-time KPIs. • Integrate close to hardware on embedded Linux (x86/ARM), optimize memory/I/O paths, and ensure cache-efficient data layouts. • Profile and debug performance (gdb, perf, valgrind, VTune), identify bottlenecks, and drive continuous improvements. • Define clean interfaces between L1 and upper layers (L2/L3) and O-RU; collaborate with system architects, protocol engineers, and QA teams to deliver carrier-grade features. • Write unit/integration tests (GoogleTest), support hardware-in-the-loop testing, and contribute to CI/CD and documentation. • Participate in code reviews and uphold high engineering standards.
Job Requirements
- 3+ years of hands-on modern C++ (C++14/17/20) in performance-critical systems; strong multithreading and memory-management skills.
- Solid understanding of DSP fundamentals and 5G NR PHY concepts (OFDM, MIMO, synchronization, channel coding LDPC/Polar).
- Proven experience with SIMD vectorization and cache-aware, low-latency design.
- Proficiency in Linux development (toolchain, CMake, Git) and debugging/profiling tools.
- Experience with embedded/real-time systems and working close to hardware.
- Ability to read and apply 3GPP specifications.
- Very good English (spoken/written).
Benefits
- Competitive salary package that grows with your experience and impact
- Access to world-class telecommunications knowledge base and comprehensive training resources
- Time for training, conferences, and self-development with ample opportunities for personal growth
- Opportunities for growth and advancement based on merit
- Ownership of cutting-edge, patent-worthy technology that shapes global connectivity
- Exposure to the latest technology and tools that push the boundaries of innovation
- Diverse, friendly, and talented international team of engineers and domain experts
- Collaborative, low-ego environment that rewards initiative and values your input
- Flexible working hours that promote healthy work-life balance
- Regular integration events that foster team bonding and camaraderie
