Job summary

NVIDIA is growing a senior systems software engineer team focused on making our compute software stack first-class on NVIDIA CPU platforms. You will lead cross-stack efforts across compiler, platform, performance, library, and applications teams to drive measurable outcomes and turn adoption barriers into repeatable engineering practices.

As a senior engineer, you will evaluate GCC/LLVM toolchains, integrate new workflows into large build systems, and document validated approaches for reuse.

Qualifications

• BS, MS, or PhD in Computer Science, Computer Engineering, Electrical Engineering, or related field, or equivalent experience. 8+ years of relevant systems software engineering experience.
• Strong C and C++ development, debugging, and code-review skills.
• Strong Linux systems knowledge and hands-on experience with complex native software stacks.
• Practical experience with GCC or LLVM/Clang, linkers, compiler options, and build systems.
• Experience working in large, multi-component codebases and CI environments.
• Experience with performance profiling, root-cause analysis, and before-and-after validation.
• Ability to lead projects with substantial technical and organizational ambiguity.
• Excellent written and verbal communication and a record of effective cross-team collaboration.

Responsibilities

• Lead toolchain, build, code-health, and performance-workflow adoption projects across large software components.
• Evaluate and deploy supported GCC and LLVM/Clang toolchains, compiler options, linkers, sysroots, and cross-compilation configurations.
• Integrate modern toolchains and workflows into complex build systems and continuous‑integration environments.
• Establish useful Clang diagnostic builds and targeted sanitizer coverage in partnership with component owners.
• Use profiling, PMU data, flamegraphs, and binary/source analysis to identify actionable performance and code-quality findings.
• Build automation, wrappers, validation scripts, dashboards, and migration helpers where they improve adoption and repeatability.
• Drive complex blockers to the appropriate compiler, runtime, library, infrastructure, or component owner.
• Document validated approaches as reusable playbooks for other engineering teams. Communicate technical results and tradeoffs clearly to engineers and leadership.
