Senior Software Engineer, CUDA C++ Core Libraries

Details

NVIDIA’s accelerated computing platform is foundational to modern HPC and AI. At the center of this platform are CUDA Core Libraries that provide the algorithms, abstractions, and runtime capabilities needed to build fast, reliable, and scalable GPU-accelerated software.

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.

Responsibilities

• 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.

Requirements

• 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

• 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.

Compensation & Benefits

• Base salary ranges provided: 184,000 USD - 287,500 USD for Level 4, and 224,000 USD - 356,500 USD for Level 5. Your base salary will be determined based on your location, experience, and the pay of employees in similar positions.
• You will also be eligible for equity and benefits.
