Build and optimize modern AI systems by experimenting with LLMs and multimodal models, then turning prototypes into production-quality Python and PyTorch components. You’ll run and improve inference performance using tools like vLLM, measure latency/throughput and GPU memory constraints, and develop evaluation frameworks for model quality and behavior. You’ll deploy model-backed services, troubleshoot failures, and reproduce or test research ideas.
