GPU Power & Performance Systems Engineer — Real-Time DVFS

NVIDIA; Santa Clara (CA); On-site; USD 184,000 - 357,000; Full time

Job summary

NVIDIA is seeking a System Software Engineer to join the GPU Performance and Power Management Software team. You will design, develop, and debug production software for P-states and DVFS, interfacing with hardware, drivers, OS, and AI workloads.

You will work across design, pre-silicon, validation, silicon bring-up, and production support, helping to deliver best-in-class power, performance, and reliability in data-center GPUs.

Qualifications

• BS or MS in Computer Science, Computer Engineering, Electrical Engineering, or equivalent experience.
• 8+ years of experience crafting system software, embedded firmware, device drivers, or other hardware-related production software.
• Strong programming skills in C, including developing, debugging, and maintaining complex low-level software.
• Deep understanding of operating-system fundamentals, device-driver architecture, embedded or real-time software, concurrency, interrupt handling, and hardware programming.
• Experience interpreting hardware specifications and developing software interfaces for registers, telemetry, interrupts, and control mechanisms.
• Strong understanding of computer architecture and hardware-software interactions.
• Proven ability to independently debug complex, cross-layer problems across software and hardware.
• Demonstrated ability to own technically challenging features or subsystems and drive them to production in collaboration with cross-functional teams.
• Excellent written and verbal communication and presentation skills.

Responsibilities

• Architect, build, implement, and debug GPU power and performance management software, with emphasis on P-state management and DVFS.
• Develop control policies, mechanisms, and real-time software that optimize GPU performance, power, thermals, and energy efficiency KPIs under demanding data-center workloads.
• Own focus area and drive features across the full product lifecycle, including requirements, architecture, implementation, pre-silicon validation, silicon bring-up, productization, and production support.
• Collaborate with GPU architects and hardware designers to define hardware-software interfaces and shape the power-management capabilities of next-generation processors.
• Analyze complex interactions among workloads, clocks, voltages, power limits, thermals, telemetry, and system-level policies.
• Lead investigation and resolution for complex power, performance, stability, and reliability issues spanning firmware, drivers, hardware, and platform software.
• Develop validation strategies and automation for functional correctness, transition latency, performance-per-watt, and robustness across operating conditions.
• Build clear architecture, interface, and feature specifications for new power and performance management capabilities.
• Partner effectively with distributed teams across architecture, ASIC, firmware, drivers, validation, platform, and data-center systems.
• Influence next generation system software by building internal scalable architecture frameworks.
