Senior System Software Engineer, NVLink Fusion

Location: US, CA, Santa Clara, US, MA, Westford

Time Type: Full time

Job Description

We are looking for a Senior System Software Engineer to develop low-level software for NVIDIA NVLink Fusion, a high-bandwidth, low-latency interconnect platform for next-generation accelerated computing systems. You will design and implement kernel-mode drivers and embedded firmware, working across the product lifecycle—from architecture and pre-silicon development through silicon bring-up, productization, production, and partner deployment.

You will collaborate closely with GPU and system architects, ASIC designers, firmware and driver teams, validation engineers, and external technology partners to deliver reliable, high-performance interconnect solutions.

What youll be doing:

• Design, implement, and maintain next-generation NVLink Fusion features across one or more low-level software layers, including kernel-mode drivers and embedded firmware or microcode.
• Drive features across the product lifecycle, including requirements, architecture, design, implementation, pre-silicon verification, silicon bring-up, validation, productization, and production support.
• Develop unit, integration, and system-level tests, diagnostics, and automation across pre-silicon and post-silicon environments.
• Debug complex hardware, firmware, kernel, and system-level issues across the hardware/software boundary.
• Collaborate with internal engineering teams and external technology partners to integrate, validate, and debug NVLink Fusion platforms.
• Develop low-level production software primarily in C and C++
• Lead and participate in design and code reviews, build technical consensus across teams, and improve software quality, maintainability, and release readiness.

What we need to see:

• Bachelor’s degree or higher in Electrical Engineering, Computer Engineering, Computer Science, or a related field (or equivalent experience)
• 5+ years of relevant software, firmware, or systems development experience, or equivalent demonstrated expertise designing, implementing, and debugging low-level software.
• Strong programming skills in C and/or C++, along with proficiency in Python or a comparable scripting language.
• Experience in one or more of the following areas: 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, including 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.
• Experience 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 a team environment.

Ways to stand out from the crowd:

• Experience using Rust for systems, kernel, firmware, or embedded software development.
• Experience with Linux kernel development, device drivers, embedded RTOS environments, or microcontroller firmware, including performance, security, or reliability considerations.
• 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 or agentic tools to software development, verification, debugging, or root-cause analysis, with sound judgment around validation, security, and appropriate use.
