Job summary

NVIDIA is seeking a Senior System Software Engineer to develop and optimize system software for next-generation O-RAN infrastructure at our Santa Clara campus. You will work at the intersection of SoC architecture, cellular workloads, firmware, and operating systems to deliver high performance and energy efficiency across RUs and DUs, including pre-silicon bring-up and post-silicon deployment.

Responsibilities include designing and tuning system software, developing power-management policies,

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++, and proficiency in Python or similar scripting language.
• 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 OS internals, Linux kernel development, device drivers, concurrency, virtual memory, and real-time or latency-sensitive programming.
• Hands-on expertise in performance measurement, workload characterization, data analysis, bottleneck identification, and system optimization.
• Knowledge of SoC power-management concepts like DVFS, clock and power gating, thermal management, and power/performance budgeting.

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 power-management capabilities such as DVFS, clock and power gating, idle-state management, and thermal controls.
• 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 decisions and identify issues.
• Evaluate system behavior against O-RAN and cellular-interface requirements for timing, synchronization, latency, throughput, and reliability.
• Influence future SoC and cellular-software architectures based on workload analysis.
