About the role

Senior System Software Engineer to develop and optimize system software for next-generation O-RAN infrastructure, focusing on 5G/6G workloads, power management, and performance on SoCs used in Radio Units and Distributed Units.

Responsibilities

  • Design, develop, test, and optimize system software and firmware for SoCs used in O-RAN and cellular infrastructure.
  • Develop power-management policies and performance optimizations across CPU, GPU, accelerator, memory, interconnect, I/O, and networking subsystems.
  • Analyze RU and DU workloads to identify architectural and system-level bottlenecks (compute, memory bandwidth, latency, synchronization, data movement).
  • Develop and tune power-management capabilities (DVFS, clock/power gating, idle-state management, thermal controls, system-level power budgeting).
  • Create performance and power models, measurement tools, benchmarks, and automated test infrastructure for pre-silicon and post-silicon environments.
  • Use simulation, emulation, prototyping, and production silicon to validate architectural decisions and identify power/performance issues.
  • Evaluate system behavior against O-RAN and cellular-interface requirements (timing, synchronization, latency, throughput, reliability).
  • Influence future SoC, platform, and cellular-software architectures based on workload analysis and measurements from deployed systems.

Qualifications

  • Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or related field, or equivalent experience.
  • 5+ years of relevant experience in system software, embedded software, firmware, computer architecture, cellular infrastructure, or performance engineering.
  • Demonstrated experience developing and debugging software for complex SoCs or embedded platforms.
  • Strong programming skills in C/C++, proficiency in Python or similar scripting language.
  • Strong understanding of computer architecture and hardware-software interaction (multicore systems, memory hierarchies, caches, interconnects, interrupts, memory-mapped I/O, DMA).
  • Experience with operating-system internals, Linux kernel development, device drivers, concurrency, virtual memory, and real-time/latency-sensitive programming.
  • Hands-on expertise in performance measurement, workload characterization, data analysis, bottleneck identification, and system optimization.
  • Working knowledge of SoC power-management concepts (DVFS, clock/power gating, thermal management, power/performance budgeting).
  • Strong grasp of cellular infrastructure and radio-access-network architecture.
  • Knowledge of 5G interfaces and protocols and 6G evolution (3GPP NR, O-RAN Open Fronthaul, eCPRI, synchronization and timing technologies).
