The team of over 800 employees includes more than 400 highly skilled engineers with deep expertise across hardware and software engineering, as well as an in-house AI R&D team.

About the role:

AI Studio is a part of Nebius Cloud, one of the world’s largest GPU clouds, running tens of thousands of GPUs. We are building an inference platform that makes every kind of foundation model — text, vision, audio, and emerging multimodal architectures — fast, reliable, and effortless to deploy at massive scale.

Responsibilities:

Develop and optimize low-level kernels and runtime components for AI inference

Improve performance of inference engines GPU platforms

Profile and debug system-level and hardware-level performance issues

Integrate support for new hardware architectures (Hopper, Blackwell, Rubin)

Collaborate with ML and backend teams to optimize end-to-end execution

Required Qualifications:

Strong proficiency in C++, OR expertise in GPU programming with a focus on low-level high-performance coding and memory management

Experience in GPU programming or systems-level software development, e.g. operating system internals, kernel modules, or device drivers

Hands-on experience with profiling and debugging tools to identify performance issues on both CPUs and GPUs, and the ability to optimize code based on those findings.

Solid understanding of CPU/GPU architecture and memory hierarchy

Preferred Qualifications:

Experience with GPU computing programming: CUDA, ROCm, CUTLASS, Cute, ThunderKittens, Triton, Pallas, Mosaic GPU

Familiarity with ML inference runtimes (e.g. TensorRT, TVM)

Knowledge of Linux internals, drivers, or compiler toolchains

Experience with tools like perf, VTune, Nsight, or ROCm profiler

Familiarity with popular inference engines (e.g. such as vLLM, sglang, TGI)
