  • Drive the adoption and scalability of Generative AI offerings within C3 AI products.

  • MS or PhD in Computer Science, Electrical Engineering, Statistics, or equivalent fields.
  • Applied Machine Learning experience (regression and classification, supervised, and unsupervised learning).
  • Strong mathematical background (linear algebra, calculus, probability, and statistics).
  • Proficiency in Python and object-oriented programming.
  • Strong experience working with machine learning and natural language processing techniques and tools.
  • Strong experience using Generative AI models, with a good understanding of deep learning model classes such as GPT, VAE, and GANs, as well as their hyperparameters.
  • Strong experience with retrieval methods e.g. using embeddings.
  • Strong experience using key Python packages for data wrangling, machine learning and deep learning such as pandas, sklearn, TensorFlow, torch, transformers, LangChain, etc.
  • Experience in Prompt Engineering and few-shot techniques to enhance LLM's performance on specific tasks.
  • Experience with training and fine-tuning deep learning models, especially LLMs, and how to tune hyperparameters to ensure task generalization.
  • Ability to drive a project and work both independently and within a cross-functional team.
  • Smart, motivated, can-do attitude, innovative and seeks to make a difference in a fast-paced environment.
  • Excellent verbal and written communication, able to articulate complex concepts with a non-technical audience.
Preferred Qualifications:

  • Experience with embedding model training and retrieval method evaluation approaches.
  • Experience with LLM architectures, adapters, Mixture of Experts (MoEs) pretraining and fine-tuning techniques.
  • Experience with design, deployment, and evaluation of LLM-powered agents and tools and orchestration approaches.
  • Experience with reinforcement learning approaches in the context of fine-tuning LLM outputs.
  • Experience with time series analysis and multivariate time series modeling.
