• Highly competent with Linux/ MacOS operating systems including file system, command line, and scripting.

• Strong understanding of commonly used machine learning and deep learning algorithms, processes, tools and platforms (e.g. HuggingFace) and experience with tuning and optimization for efficient implementation.

• Proven experience working with large structured and unstructured data sets; experience with NLP; experience with Computer Vision, preferably with OCR.

• Experience with foundational LLMs and using GPT or other Transformer models for NL search and information retrieval. Ability to enhance LLM output quality through prompt engineering, Retrieval Augmented Generation, and fine tuning. Proven experience using embeddings, vector databases, and indexing to extract information and insights quickly from huge volumes of numeric and textual data.

• Experience working with DevOps/ MLOps for model release and deployment

• Strong experience working with AWS (in the console and with boto3), working with EC2 instances (writing Lambdas, Sagemaker model pipelines) and an ability to work with data from various sources (e.g., DynamoDB, S3)
