What you’ll do

\n

\n
• Develop distributed training pipelines that support complex models and large datasets.
\n
• Build tools that automate experimentation, hyperparameter searches, and model retraining.
\n
• Improve data pipelines, parallelism strategies, and checkpointing to support training at scale.
\n
• Partner with HPC specialists to increase training throughput and reduce compute costs.
\n
• Extend ML frameworks and open-source components to better support research workloads.
\n
• Design scalable infrastructure that helps researchers work effectively with high-volume trading data.
\n
• Evaluate and integrate technologies that improve model development, evaluation, and deployment.
\n
• Own systems through testing, rollout, and ongoing operation, incorporating feedback from researchers.
