Key Responsibilities
- Software Stack Maintenance: Maintain, update, and optimize critical ML libraries and frameworks including JAX, PyTorch, CUDA, and ROCm across multiple environments and hardware configurations.
- End-to-End Stack Ownership: Build, maintain, and continuously improve the entire ML software stack from ROCm/CUDA drivers to high-level JAX/PyTorch tooling.
- Distributed Training Optimization: Ensure all model implementations are efficiently sharded, partitioned, and configured for large-scale distributed training.
- System Integration: Continuously integrate and validate modules for runtime correctness, memory efficiency, and scalability across multi-node GPU/accelerator clusters.
- Profiling & Performance Analysis: Conduct detailed profiling of compilation graphs, training workloads, and runtime execution to optimize performance and eliminate bottlenecks.
- Debugging & Reliability: Troubleshoot complex hardware–software interaction issues, including vLLM compilation failures on ROCm, CUDA memory leaks, distributed runtime failures, and kernel-level inconsistencies.
- Collaborate with research, infrastructure, and kernel engineering teams to improve system throughput, stability, and developer experience.
Must-Haves
- 5+ years of industry experience in ML systems, distributed training, or related fields.
- Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or related technical fields.
- Strong programming experience in Python, C++, and familiarity with ML tooling and distributed systems.
- Deep understanding of profiling tools (e.g., Nsight, ROCm Profiler, XLA profiler, TPU tools).
- Deep expertise with partitioning configuration on the modern ML frameworks such as PyTorch and JAX.
- Experience with multi-node distributed training systems and orchestration frameworks (DTensor, GSPMD, etc.).
- Hands-on experience maintaining or building ML training stacks involving CUDA, ROCm, NCCL, XLA, or similar technologies.
Nice-to-Haves
Extensive experience with the XLA/JAX stack, including compilation internals and custom lowering paths.
Familiarity with distributed serving or large-scale inference frameworks (e.g., vLLM, TensorRT, FasterTransformer).
Background in GPU kernel optimization or accelerator-aware model partitioning.
Strong understanding of low-level C++ building blocks used in ML frameworks (e.g., XLA, CUDA kernels, custom ops).
