We seek a senior software engineer to join our AI Networking co-design and benchmark R&D team. In this pivotal role, you will be responsible for building and productizing machine learning tools that use ML-based combinatorial optimization and build space exploration (DSE) techniques. These tools will be employed to optimize AI workloads across large GPU and CPU clusters, thereby ensuring the most efficient and productive utilization of system resources at data center scale.
You will interact with diverse hardware and platforms, such as Host Channel Adapters (HCAs), Switches, CPUs, GPUs, and complete Systems. Furthermore, the role requires engagement across multiple software layers, including LLM applications, machine learning frameworks, and communication and computing libraries. You will develop tools and methodologies using Machine Learning (ML) for comprehensive performance analysis and optimization, potentially incorporating learning-based agentic techniques.
This work involves deep-diving across the software stack, from LLM applications and ML frameworks down to communication and computing libraries. This position offers a distinct opportunity to support the core infrastructure powering the next generation of large-scale AI systems.
Responsibilities:
- Design and implement resource allocation and combinatorial optimization techniques (e.g., reinforcement learning, LLM agents for DSE, Bayesian optimization and other multi-objective optimization techniques) to optimize LLM models at datacenter scale.
- Research, develop, and deploy AI/ML techniques to optimize large-scale Deep Learning (LLM) training and inference on NVIDIA supercomputers and distributed systems. This includes a focus on high-performance networking and NVIDIA communication libraries.
- Build and productionize ML-based tools for performance prediction and optimization, with a strong emphasis on networking aspects.
- Develop and deploy a scalable, reliable data curation pipeline capable of handling complex data types, such as time series and PyTorch model graphs, to effectively support the training of high-performance Machine Learning models.
- Collaborate across hardware and software teams to deliver valuable performance analysis insights.
- Lead performance test planning, establish performance targets for new technologies and solutions, and drive efforts to achieve those performance goals.
Requirements:
- PhD or Master's degree in Computer Science, Software Engineering, or equivalent experience.
- 4+ years of experience applying machine learning techniques to computer architecture and system optimization problems. Desired experience involves bringing to bear ML at the intersection of at least two of the following areas: HPC, networking, and AI applications.
- Hands-on experience developing and deploying various learning algorithms (e.g., reinforcement learning, offline RL, supervised learning) to tackle optimization challenges within computer architecture, system design, or networking domains.
- Proficiency in building and using ML models with leading frameworks such as PyTorch or TensorFlow, or JAX.
- Proven ability to apply GNNs/transformers-based optimization to PyTorch model graph and Kineto execution traces.
- Expertise combining knowledge of NVIDIA GPUs, the CUDA library, and deep learning frameworks (TensorFlow/PyTorch) with networking concepts, including collective communication libraries (like NCCL) and protocols (such as RoCE and RDMA).
- Strong programming capabilities in Python, Bash, and C++.
- A collaborative teammate with effective communication and interpersonal abilities.
