# Large Language Model (LLM) Systems Scientist

Large Language Model (LLM) Systems Scientist Research and develop multi-agent orchestration and decision-policy algorithms including inference time agent routing, task decomposition and coordination across both open weight and proprietary LLM and Transformer-based models using python, PyTorch and/or Tensorflow. Develop and scale vector-based retrieval and augmented generation (RAG) systems including vector index optimization, retrieval-latency tuning, hybrid (dense + sparse) search across SQL datastore, and embedding-pipeline throughput to support high-volume agentic reasoning across multiple AI applications. Research and develop novel training algorithms, including contrastive learning, using PyTorch and/or Tensorflow to specialize and align multi-agent LLM systems, and productionize them as platform-level training capabilities managed under Git-based version control and CI/CD. Design and scale the platform-level evaluation framework, including statistical benchmarking pipelines implemented using Python, pandas and numpy, automated regression suites, and quality and reliability dashboards, for evaluating LLM-driven generation and inference systems.
