Senior Software Engineer, CUDA C++ Core Libraries

• Design and implement foundational CUDA C++ libraries, parallel algorithms, utilities, and runtime abstractions.
• Compose and optimize GPU algorithms from high-level generic interfaces through low-level implementation.
• Design stable interoperability boundaries that allow core C/C++ functionality to be consumed efficiently from Python and Rust.
• Balance performance, compile time, portability, compatibility, usability, and long-term API evolution.
• Own features throughout their lifecycle: design, implementation, testing, profiling, benchmarking, documentation, release, and maintenance.
• Improve developer productivity through diagnostics, examples, build integration, tests, benchmarks, and continuous integration.
• Collaborate with Python, Rust, compiler, and runtime engineers during architecture, design, and code reviews.
• Engage with users on performance investigations, API feedback, and correctness issues.

We are hiring a Senior Software Engineer to advance the C++ foundation of CUDA Core Libraries. You will design and optimize high-performance algorithms and APIs for C++ developers. You will join the team building the foundational libraries, algorithms, and language/runtime infrastructure that make CUDA a speed-of-light experience for developers and AI coding agents alike., * BS, MS, or PhD in Computer Science, Computer Engineering, or a related field, or equivalent experience and 8+ years of relevant software-development experience.

• Strong production programming skills in C and C++, with deep knowledge of modern C++.
• Experience with generic programming, templates, type systems, and standard-library design principles.
• Proven experience developing systems-level software with demanding performance, concurrency, and compatibility requirements.
• Practical experience with CUDA or another parallel or heterogeneous programming environment.
• Experience developing production software or foundational libraries, including testing, profiling, benchmarking, and code review.
• Understanding of API and ABI compatibility and the challenges of exposing C/C++ functionality to other languages.
• Ability to work independently, define project scope, and drive complex work to completion.
• Clear written communication skills for architecture documents, API specifications, and developer documentation.
• Comfort working in large C/C++ codebases with build systems, toolchains, and continuous-integration infrastructure.

Ways to stand out from the crowd:

• Strong understanding of CPU/GPU architecture and performance optimization, with hands-on experience in GPU-accelerated stacks (CUDA C++/Python, PyTorch, JAX, Numba, CuPy, or similar).
• Proficiency with modern C++ and GPU libraries such as Thrust, CUB, and libcudacxx.
• Experience with compiler infrastructure and tooling, including LLVM, Clang, or MLIR.
• Knowledge of binary interfaces, linking, versioning, cross-platform distribution, and interoperability across Python, Rust, and C/C++ stacks.
• Demonstrated interest in developer tools, library design, and improving developer productivity.
