  • Production experience with LLMs including RAG, Evals, Agentic patterns, and information retrieval techniques.
  • Foundational understanding of Python, Pytorch, and Hugging Face transformers library
  • Knowledge in the latest NLP-related algorithms and methods such as LLMs, transformers, sequence-to-sequence models, word and sentence embeddings, attention, information retrieval, etc
  • Experienced software engineering, data modeling, and debugging/profiling fundamentals
  • A Masters or PhD in Machine learning, Computer Science, Mathematics, Statistics, or another quantitative discipline or 3+ years equivalent industry experience

Nice to Haves:

  • Demonstrated ability to drive selection of machine learning approaches to solve specific problems coupled with the ability to clearly communicate tradeoffs
  • Experience with one or more model inference optimization libraries (TensorRT, ONNX, torch script, vLLM, etc)
  • General software design patterns (REST, MVC, Auto-scaling, etc.)
  • Experience supporting machine learning solutions for multiple languages
