• Designing and extending MLIR dialects, building conversion pipelines.
• Implementing and optimising passes.
• Extending and maintaining backends, curating and writing custom kernels (CUDA/HIP) with runtime integration for optimal occupancy and bandwidth use.
• Profiling, measuring, and preventing regressions using tools such as nsight-compute, rocprof, vtune, and perf, supported by CI’d performance suites.
• Driving upstream improvements to LLVM/MLIR, authoring RFCs, and reviewing PRs.
• Collaborating with model optimisation and runtime teams on ABI, graph partitioning, and kernel launch strategies.
