Senior Systems Software Engineer, Compute Stack Acceleration

NVIDIA; California (MO); On-site; USD 184,000 - 356,500; Full time

Job summary

NVIDIA is growing a senior engineering team focused on making our compute software stack first-class on NVIDIA CPU platforms. The engineer will lead cross-stack efforts, validate new capabilities, and turn successful approaches into reusable engineering practices across the stack.

You will work with compiler, platform, performance, library, and application teams to evaluate GCC/LLVM toolchains, integration into large build systems, and drive data-driven improvements with before-and-after

Qualifications

• BS/MS/PhD in CS/CE/EE or equivalent experience with 8+ years in systems software.
• Strong C and C++ development, debugging, and code-review skills.
• Strong Linux systems knowledge with complex native software stacks.
• Experience with GCC or LLVM/Clang, linkers, and build systems.
• Experience with large multi-component codebases and CI environments.
• Experience with profiling, root-cause analysis, and validation.
• Ability to lead projects with ambiguity.
• Excellent written and verbal communication and cross-team collaboration.

Responsibilities

• Lead toolchain, build, code-health, and performance-workflow adoption across large software components.
• Evaluate and deploy GCC and LLVM/Clang toolchains, options, linkers, and cross-compilation.
• Integrate modern toolchains into complex build systems and CI environments.
• Establish Clang diagnostic builds and targeted sanitizer coverage with owners.
• Use profiling data, flamegraphs, and analysis to drive improvements.
• Develop automation, dashboards, and migration helpers to boost adoption.
• Escalate blockers to the appropriate compiler or runtime owner.
• Document approaches as reusable playbooks for engineering teams.

Job description

NVIDIA is growing a senior engineering team focused on making our compute software stack first-class on NVIDIA CPU platforms. The team turns modern toolchains, build and code-health practices, performance-analysis workflows, and optimization techniques into repeatable improvements across real software components.

We are looking for an experienced systems software engineer who can lead cross-stack engineering efforts from an ambiguous adoption problem to a measurable outcome. You will work closely with compiler, platform, performance, library, and application teams to validate new capabilities, resolve integration blockers, produce credible before-and-after evidence, and turn successful approaches into reusable engineering practices. Depending on your background and project needs, your initial work may emphasize toolchain, build, and code-health adoption or profiling, optimization, and evidence-routing workflows. The role is intentionally broad enough to evolve as the team identifies the highest-leverage opportunities across the stack.

What You\'ll Be Doing

• 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. Evaluate techniques such as link-time optimization, profile-guided optimization, AutoFDO, and BOLT on representative software.
• 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. Measure changes in runtime, code size, build time, launch latency, throughput, quality, or engineering velocity.
• 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.

What We Need To See

• BS, MS, or PhD in Computer Science, Computer Engineering, Electrical Engineering, or a 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.

Ways To Stand Out From The Crowd

• Experience with Arm64 systems, CPU architecture, vectorization, or SVE. Experience with LTO, PGO, AutoFDO, BOLT, binary optimization, or code-layout analysis.
• Hands-on experience with Clang diagnostics, AddressSanitizer, or other code-health workflows.
• Familiarity with PMU analysis, perf, flamegraphs, BRBE, SPE, ETM, or similar profiling technologies.
• Experience with cross-compilation, sysroots, large monorepositories, Perforce-scale development, or distributed build systems.
• Experience turning a successful migration or optimization into a maintained workflow used by multiple teams. Python or other scripting experience for engineering automation and data analysis.
