Senior System Software Engineer - GPU Power Management

NVIDIA is redefining accelerated computing and powering the next era of artificial intelligence. Our data-center platforms bring together GPUs, CPUs, networking, systems, and software to solve some of the world’s most exciting computing problems. We are looking for a Senior System Software Engineer to join NVIDIA’s GPU Performance and Power Management Software team. You will be responsible for architecting production software for performance states (P-states) and Power Management Controllers. Your work will also cover dynamic voltage and frequency scaling (DVFS) and power-management control system technologies for next-generation data-center GPUs.

You will work at the intersection of hardware architecture, embedded firmware, device drivers, operating systems, and AI workloads. Your responsibilities will span the entire product lifecycle-from initial architectural design and pre-silicon validation through silicon bring-up, productization, and deployment in extensive data-center infrastructures. This is an outstanding chance to influence how next-generation NVIDIA GPUs provide top-tier performance, energy efficiency, and reliability.

What You’ll Be Doing:

• Architect, build, implement, and debug GPU power- and performance-management software, with particular emphasis on P-state management and DVFS.
• Develop real-time controllers, policies, and mechanisms that dynamically optimize GPU performance, power, thermals, and energy efficiency under demanding data-center workloads.
• Drive features across the full product lifecycle: 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 influence the power-management capabilities of next-generation processors.
• Analyze complex interactions among workloads, clocks, voltages, power limits, thermals, telemetry, and system-level policies.
• Lead the investigation and resolution of 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 compose specifications for new power-management features.
• Partner with geographically distributed architecture, ASIC, firmware, driver, validation, platform, and data-center systems teams.

• BS or MS degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field-or equivalent experience.
• At least 12+ years of extensive industry experience crafting system software, embedded firmware, device drivers, or other hardware-related production software.
• Strong programming skills in C, including experience 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 problems across multiple software and hardware layers.
• Excellent written and verbal communication skills, with a track record of working effectively across organizational and geographic boundaries.

Ways to Stand Out From the Crowd:

• Hands-on experience with GPU, CPU, accelerator, or SoC power and performance management.
• Background with crafting or implementing P-state selection, DVFS, clock-control, voltage-control, power-capping, thermal-management, throttling, or workload-aware control policies.
• Experience developing real-time feedback controllers, including reasoning about stability, responsiveness, hysteresis, latency, and noisy telemetry.
• Understanding of electrical and platform considerations such as voltage-frequency relationships, transient power, thermal limits, power delivery, and system-level power budgets.

Your base salary will be determined based on your location, experience, and the pay of employees in similar positions. The base salary range is 224,000 USD - 356,500 USD for Level 5, and 272,000 USD - 431,250 USD for Level 6.
