• Experience with one or more of the following:
• Distributed training frameworks (e.g., PyTorch FSDP, Megatron-style parallelism)
• Reinforcement learning training systems
• GPU programming (CUDA, Triton) or compiler technologies

Preferred Qualifications:

• Experience working on large-scale ML systems or infrastructure projects
• Contributions to open-source ML systems or performance tooling
• Publications in ML systems, distributed systems, or related areas (a plus but not required)
