Senior System Software Engineer - Nixpkgs

NVIDIA•Us, CA

About The Position

NVIDIA has been transforming computer graphics, PC gaming, and accelerated computing for more than 25 years. It’s a unique legacy of innovation that’s fueled by great technology—and amazing people. Today, we’re tapping into the unlimited potential of AI to define the next era of computing. An era in which our GPU acts as the brains of computers, robots, and self-driving cars that can understand the world. Doing what’s never been done before takes vision, innovation, and the world’s best talent. As an NVIDIAN, you’ll be immersed in a diverse, supportive environment where everyone is inspired to do their best work. Come join the team and see how you can make a lasting impact on the world. Are you passionate about open-source packaging and delivering GPU-accelerated software to developers worldwide? We are seeking a System Software Engineer to join Kitmaker, our team responsible for getting NVIDIA's software out the door. As NVIDIA scales its AI computing and accelerated software portfolio, first-class support in the Nix ecosystem is critical to reaching developers who rely on reproducible, declarative system configurations. Kitmaker oversees packaging and release for many business areas of NVIDIA, from CUDA Toolkit to our expanding compute software stack, and we're investing heavily in growing our presence in the nixpkgs ecosystem. If you love building high-quality Nix packages, contributing upstream, and bridging the gap between NVIDIA's proprietary software and open-source packaging communities, you'll thrive on our team!
