Senior System Software Engineer, NVLink Fusion

Job Title

Senior System Software Engineer, NVLink Fusion

Role Summary

Develop low-level software (kernel-mode drivers, embedded firmware/microcode) for NVIDIA NVLink Fusion, a high-bandwidth, low-latency interconnect for accelerated computing systems. Work across architecture, pre-silicon development, silicon bring-up, validation, productization, and partner deployment with cross-functional engineering teams.

Experience Level

Senior - typically requires 5+ years of relevant software, firmware, or systems development experience or equivalent demonstrated expertise.

Responsibilities

Primary responsibilities include design, implementation, verification, and production support for low-level interconnect software.

• Design, implement, and maintain kernel-mode drivers and embedded firmware or microcode for NVLink Fusion.
• Drive features across requirements, architecture, design, pre-silicon verification, silicon bring-up, validation, productization, and production support.
• Develop unit, integration, and system-level tests, diagnostics, and automation for pre- and post-silicon environments.
• Debug complex hardware, firmware, kernel, and system-level issues across the hardware/software boundary.
• Collaborate with GPU and system architects, ASIC designers, firmware and driver teams, validation engineers, and external partners to integrate and validate platforms.
• Lead and participate in design and code reviews; build technical consensus and improve software quality and release readiness.
• Develop production software primarily in C and C++.

Requirements

Must-have technical skills and experience for the role.

• 5+ years of experience in low-level software, firmware, or systems development, or equivalent demonstrated expertise.
• Strong programming skills in C and C++; proficiency in Python or comparable scripting language.
• Experience with operating-system kernels, device drivers, embedded firmware, microcode, high-speed interconnects, networking, or low-level system software.
• Strong understanding of computer architecture and hardware/software interaction: memory-mapped I/O, interrupts, DMA, concurrency, memory ordering, and device I/O.
• Experience debugging complex systems using logs, traces, debuggers, hardware diagnostics, simulation, or emulation.
• Familiarity with software engineering practices including technical design, peer review, testing, release management, and production maintenance.
• Experience collaborating with hardware development teams during pre-silicon development, silicon bring-up, or platform validation.
• Strong communication, collaboration, and analytical problem-solving skills; ability to work independently and in teams.

Nice-to-have:

• Experience using Rust for systems, kernel, firmware, or embedded development.
• Linux kernel development, device drivers, RTOS, or microcontroller firmware experience.
• Familiarity with NVLink, PCIe, CXL, InfiniBand, Ethernet, cache-coherent interconnects, or other high-speed I/O technologies.
• Experience with pre-silicon simulation, emulation, FPGA prototyping, silicon bring-up, or cross-company platform integration.
• Experience applying AI-assisted tools to development, verification, debugging, or root-cause analysis with appropriate validation and security judgment.

Education Requirements

Bachelor's degree or higher in Electrical Engineering, Computer Engineering, Computer Science, or a related field - or equivalent practical experience.
