Senior LLVM Compiler Engineer

About the role

We are seeking for an expert Senior Compiler Engineer to join our Compute Compiler Team, with a focus on upstream engagement with the LLVM ecosystem and advancing NVIDIA’s compiler technology through trusted, sustained participation in open‑source communities. In this role, you will work directly with LLVM, Clang, MLIR, and related open‑source projects to upstream compiler functionality that currently lives in NVIDIA’s downstream repositories. Your collaboration with the broader LLVM community to shape designs, influence technical direction, and ensure NVIDIA’s needs are met by supplying high‑quality, maintainable solutions that benefit the ecosystem as a whole.

We are seeking an experience engineer who proficient in combining deep compiler expertise with a strong appreciation for open‑source norms, collaboration, and long‑term stewardship. Your influence will come not from authority, but from technical credibility, respect for community processes, and sustained contribution to the health and evolution of the LLVM project. If you are passionate about open‑source compiler development, upstreaming real‑world production code, and representing NVIDIA as a trusted partner in the LLVM community, we would love to hear from you.

What you will be doing:

- Work closely with LLVM, Clang, MLIR, and related open‑source communities to upstream compiler features, refactors, and infrastructure originating from NVIDIA’s downstream codebases

- Lead and contribute to design discussions, RFCs, and code reviews in upstream communities with an emphasis on long‑term maintainability and broad usefulness

- Refactor, adapt, and decompose downstream NVIDIA compiler code to meet upstream quality, abstraction, and API expectations

- Advocate for NVIDIA’s technical needs through credible engineering arguments, prototypes, and sustained community engagement

- Collaborate with internal compiler teams to identify which downstream capabilities are best suited for upstreaming and how to stage that work effectively

- Partner with architecture, performance, and product teams to translate NVIDIA hardware and software requirements into upstream‑viable compiler solutions

- Help shape NVIDIA’s long‑term open‑source LLVM strategy, balancing ecosystem health with NVIDIA’s platform goals

- Act as a technical ambassador for NVIDIA within the compiler open‑source community, strengthening trust and collaboration over time

What we need to see:

- B.S., M.S., or Ph.D. in Computer Science, Computer Engineering, or related field (or equivalent experience)

- 6+ years experience with LLVM, Clang, MLIR, or similar compiler infrastructures

- Excellent hands‑on C++ programming skills

- Solid understanding of compiler internals, including IR design, transformations, analyses, and code generation pipelines

- Experience engaging with open‑source development workflows, including design discussions, code reviews, and upstream contribution processes
