Senior Systems Software Engineer, Compute Stack Acceleration

NVIDIA is growing a senior engineering team focused on making our compute software stack first‑class on NVIDIA CPU platforms. The team turns modern tool chains, 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.

• Lead toolchain, build, code‑health, and performance‑workflow adoption projects across large software components.
• Evaluate and deploy supported GCC and LLVM/Clang tool chains, compiler options, linkers, sysroots, and cross‑compilation configurations.
• Integrate modern tool chains 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, flame graphs, 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 trade‑offs clearly to engineers and leadership.

• 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.

• Experience with Arm
  64 systems, CPU architecture, vectorization, or SVE. Experience with LTO, PGO, AutoFDO, BOLT, binary optimization, or code‑layout analysis.
• Hands‑on experience with Clang diagnostics, Address Sanitizer, or other code‑health workflows.
• Familiarity with PMU analysis, perf, flame graphs, 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.

Your base salary will be determined based on your location, experience, and the pay of employees in similar positions. The base salary range is $184,000 USD – $287,500 USD for Level 4, and $224,000 USD – $356,500 USD for Level 5.

You will also be eligible for equity and benefits.
