GPU Compiler Intern

Nvidia is hiring a GPU Compiler Intern in Zurich, Switzerland. When: Summer 2027. Posted November 11, 2026. Checked against the employer's posting on November 12, 2026.

As GPU Compiler Intern, you will develop compiler infrastructure for Python-based GPU programming, including CUTLASS CuTeDSL. You will work on DSL design, MLIR IR design, and compiler optimizations that translate expressive Python programs into high-performance NVIDIA GPU kernels.

What you will be doing: • Design and implement Python DSL features for GPU kernel authoring, including metaprogramming and IR generation. • Develop MLIR dialects, transformation passes, and lowering pipelines that preserve the information needed for effective GPU optimization.

• Design and optimize GPU kernels, exploring how IR design and compiler transformations affect generated code and performance. • Profile, benchmark, and validate compiler and kernel improvements across representative workloads.

What we need to see: • Currently pursuing or holding a Bachelor’s, Master’s, or Ph.D. degree in Computer Science, Computer Engineering, or a related technical discipline, or equivalent practical experience.

• Proficiency in Python and C++, with strong debugging and software development skills. • Understanding of how Python DSLs work, including metaprogramming, staged execution, and translation into compiler IR.

• Experience with MLIR, including IR construction, transformation passes, or lowering. • Practical experience with GPU programming, preferably CUDA, and knowledge of GPU execution and memory models.

• Familiarity with performance analysis and optimization, including profiling, memory access patterns, and parallel execution. • Experience with CUTLASS, CuTeDSL, Triton, LLVM, or other GPU compiler and kernel development tools is a plus.
