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.
