Job summary

NVIDIA in Santa Clara, CA is seeking a Senior System Software Engineer to design, develop, and optimize system software and firmware for next‑gen O-RAN infrastructure and 5G/6G workloads. You’ll work at the intersection of SoC architecture, cellular systems, firmware, and Linux to deliver high performance and energy efficiency.

Collaborate with hardware, platform, and software teams across pre‑silicon bring‑up to deployment, driving power‑management features, benchmarks, and test tooling while

Qualifications

• 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 DVFS, 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.
