Job summary

NVIDIA is seeking a highly motivated Senior System Software Engineer to develop and optimize system software for next-generation O-RAN infrastructure. You will work at the intersection of SoC architecture, cellular systems, firmware, operating systems, and radio-access-network workloads, helping deliver industry-leading performance and energy efficiency.

This role focuses on software for 5G and emerging 6G infrastructure, including Radio Units and Distributed Units, with collaboration across

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 or C++, with Python or scripting language proficiency.
• Strong understanding of computer architecture and hardware-software interaction, including multicore systems, memory hierarchies, caches, interconnects, interrupts, memory-mapped I/O, and DMA.
• Experience with 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 budgeting).
• Familiarity with 5G/6G interfaces and protocols (3GPP NR, O-RAN Open Fronthaul, eCPRI).
• Experience evaluating system behavior against timing, synchronization, latency, throughput, and reliability requirements.

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.
• Develop and tune DVFS, clock/power gating, idle-state management, thermal controls, and power budgeting.
• Create performance and power models, measurement tools, benchmarks, and automated test infrastructure.
• Use simulation, emulation, prototyping, and production silicon to validate architectural decisions and identify 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 from deployed systems.
