Research Scientist, High Performance Computing and Artificial Intelligence (Hybrid Eligible)


Ready to apply your HPC and AI skills in a premier research institution? The Analytics and AI methods at Scale (AAIMS) group in the National Center for Computational Science (NCCS) is seeking hardworking research scientists in the very broad areas of intersection of High-Performance Computing (HPC) and AI.

Examples on areas of research interest include: 

NLP and Foundational model pre-training, human-in-loop reinforcement learning and fine-tuning.
Performance analysis and optimization of large-scale AI/ML stack and applications including computational optimization of mixed-precision kernels, data parallelism, model-parallelism, collective communication patterns and strategies for large-scale, distributed machine learning using frameworks such as PyTorch and TensorFlow.
Operational data (Power, energy, CPU/GPU utilization, job scheduling, large scale storage and I/O traces, system logs) analytics to enable data-driven intelligence and facility innovation via novel applications of ML/AI techniques such as large-scale language model and causality analysis.
AI algorithms for handling sensitive data using methods such as Federated Learning, Differential Privacy, and Secure Multiparty Computing, among others.
Data analytics pipelines from the Edge to Exascale.
Visualization of large-scale HPC/AI discovery campaigns.

At the NCCS and its Leadership Computing Program (OLCF,) we provide world class computing facilities to applications across all computational domains and subject areas. Through this position you are able to impact and further the mission of NCCS and Oak Ridge National Laboratory. We are a diverse, dynamic environment that welcomes those with initiative and creativity.
