Responsibilities:

• As an Infrastructure Intern, you may work on one or more of the following areas:
• Design and optimize large-scale distributed training systems (e.g., data/model/pipeline parallelism, memory efficiency, fault tolerance)
• Contribute to reinforcement learning training frameworks and large-scale post-training systems
• Improve inference performance, latency, and throughput for foundation models
• Develop compiler or runtime optimizations for heterogeneous hardware (GPU/accelerator)
• Work on system-level performance analysis, profiling, and bottleneck diagnosis
• Build tooling and automation to improve developer productivity and system reliability

Requirements:

Minimum Qualifications:

• Currently pursuing a PhD degree in Computer Science, Electrical Engineering, or related technical fields
• Strong programming skills in Python and/or C++
• Solid understanding of systems, distributed computing, machine learning systems, or performance optimization
• Experience with one or more of the following:
• Distributed training frameworks (e.g., Py Torch 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)

As a condition of employment, all successful candidates must be able to establish authorization to work in the United States. For this position, the Company does not provide sponsorship or any immigration-related benefits.
