Senior LLVM Compiler Engineer

NVIDIA•Austin, WA

About The Position

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.

Requirements

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
Ability to navigate complex technical trade‑offs while balancing upstream community expectations with internal product needs
Strong communication skills, including technical writing, design articulation, and cross‑organizational collaboration

Nice To Haves

Proven track record of upstream contributions to LLVM or related open‑source compiler projects
Experience in successfully upstreaming non‑trivial production code from a downstream or proprietary environment
Recognition within open‑source communities as a trusted contributor or reviewer
Background in GPU architectures, CUDA, or parallel programming models
Familiarity with deep learning frameworks and performance‑critical workloads on NVIDIA GPUs

Responsibilities

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
