Senior Software Engineer, CUDA Core Libraries

NVIDIA’s accelerated computing platform is the foundation of modern HPC and AI. At the core of this platform are the CUDA Core Libraries. C++ and Python libraries that enable developers to write fast, reliable, and scalable GPU-accelerated software! We are hiring a full‑time Software Engineer to work on the CUDA Core Libraries that power GPU computing for both C++ and Python developers. This includes projects such as CCCL (Thrust, CUB, libcudacxx), cuda‑python, and numba‑cuda. You will join the team building the foundational libraries, algorithms, and language/runtime infrastructure that make CUDA a speed‑of‑light experience for developers across deep learning, scientific computing, and data analytics!

What You’ll Be Doing

• Develop and implement CUDA Core Libraries in C++ and/or Python, including parallel algorithms and idiomatic language bindings for core CUDA functionality.
• Compose, optimize, and evolve GPU algorithms and APIs, from high‑level interfaces down to low‑level performance tuning involving memory, parallelism, and synchronization.
• Own features end‑to‑end: develop, implementation, testing, benchmarking, documentation, and long‑term maintenance.
• Improve developer experience across the stack: CI, tests, benchmarks, packaging, examples, and docs.
• Collaborate with senior CUDA engineers in design reviews, code reviews, and open‑source‑style workflows.
• Engage with real users through issues, performance investigations, and API feedback.

What We Need To See

• BS, MS, or PhD in Computer Science, Computer Engineering, or a related field or equivalent experience.
• Minimum of 8+ years of related development experience.
• Strong programming skills in C++, Python, or both, with proven interest in systems‑level software (performance, memory, concurrency, API design).
• Solid understanding of modern C++ (templates, generics, standard library) and/or Python library development and packaging.
• Practical experience with parallel or heterogeneous programming (CUDA, OpenMP, GPU‑accelerated Python, or similar).
• Experience contributing to production software or open‑source libraries, including testing, profiling, and code review.
• Ability to work independently, scope problems, and drive projects to completion.
• Clear written communication for technical design and documentation.
• Comfort navigating large, multi‑language codebases (C++, Python, CMake, Pixi, CI systems).

Ways To Stand Out From The Crowd

• Strong understanding of CPU/GPU architecture and how hardware details affect performance.
• Hands‑on experience with CUDA C++, CUDA Python, PyTorch, JAX, Numba, CuPy, or similar GPU‑accelerated stacks.
• Familiarity with Thrust, CUB, libcudacxx, or other modern C++/GPU libraries.
• Experience with compiler infrastructure or tooling (LLVM, Clang tooling, MLIR).
• Demonstrated interest in developer tools, library design, and making other developers faster.

If you care deeply about performance, enjoy working at the C++/Python boundary, and want to shape the core CUDA libraries relied on by thousands of developers, this role is a direct fit.
