Senior SoC System Software Engineer – Power & Performance

NVIDIA Corporation; Santa Clara (CA); On-site; USD 152,000 - 242,000; Full time

Job summary

NVIDIA Corporation seeks an experienced systems engineer to design, develop, and optimize SoC-related software and firmware for O-RAN and cellular infrastructure in Santa Clara. You will work across CPU, GPU, accelerator, memory, interconnect, and I/O subsystems to improve performance and power efficiency.

Expect hands-on work with pre- and post-silicon validation, workload analysis, and DVFS-based optimizations. Strong C/C++ and Python skills, plus Linux kernel experience, are required.

Qualifications

• Bachelor’s or Master’s degree in CS/CE/EE or equivalent experience.
• 5+ years of relevant experience in system software, embedded software, firmware, computer architecture, cellular infrastructure, or performance engineering.
• Experience developing and debugging software for complex SoCs or embedded platforms.
• Strong programming skills in C or C++, and Python or scripting language.
• Deep understanding of computer architecture and hardware-software interaction, including multicore systems and memory hierarchies.
• Experience with OS internals, Linux kernel development, device drivers, concurrency, virtualization, and real-time programming.
• Hands-on expertise in performance measurement, workload characterization, data analysis, bottleneck identification, and system optimization.
• Knowledge of SoC power-management concepts (DVFS, clock/power gating, thermal management).

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 representative RU and DU workloads to identify architectural and system-level bottlenecks, including compute, memory bandwidth, latency, synchronization, and data-movement constraints.
• Develop and tune power-management capabilities such as dynamic voltage and frequency scaling, clock and power gating, idle-state management, thermal controls, and system-level power budgeting.
• Create performance and power models, measurement tools, benchmarks, and automated test infrastructure for both pre-silicon and post-silicon environments.
• Use simulation, emulation, prototyping, and production silicon to validate architectural decisions and identify power and performance issues.
• Evaluate system behavior against O-RAN and cellular-interface requirements, including timing, synchronization, latency, throughput, and reliability.
• Influence future SoC, platform, and cellular-software architectures based on workload analysis and measurements from deployed systems.
