About the role

  • Propose, plan, and execute applied research initiatives that will make a real-world impact on Conversational AI using Large Language Models (LLMs) within a commercial setting.
  • Use expert knowledge of Transformer architecture mechanics (Attention, Tokenization, Embeddings) to consistently find the most effective, efficient, stable, explainable, and elegant prompting and orchestration approaches.
  • Utilize modern LLM inference and retrieval pipelines.
  • Analyze large scale conversational datasets for RAG (Retrieval-Augmented Generation) optimization.
  • Bring research-inspired prompt strategies to life within production systems.
  • Create durable, flexible scientific evaluation and experimentation capabilities for non-deterministic model outputs.
  • Present findings on model behavior and context efficacy in ways that inform and guide business and product strategy.
  • Work closely with other scientists.
  • Stay current with the rapidly evolving state of Generative AI.

Requirements

  • Requires a Master's degree in Computer Science, Artificial Intelligence, Computational Linguistics, Operations Research, Industrial Engineering, or a directly related field plus two (2) years of experience as a data scientist.
  • Must have two (2) years of experience in the following (experience may be gained concurrently):
  • Programming experience in Python
  • Developing and designing Large Language Model (LLM) interaction flows, evaluation frameworks, or advanced prompting strategies
  • Partnering with engineering teams to deploy GenAI/LLM solutions into production
  • Must have one (1) year of experience in the following (experience may be gained concurrently):
  • Experience with Generative AI, including Large Language Models, Prompt Engineering, Retrieval Augmented Generation (RAG), and Semantic Search/Vector Databases
  • Researching and implementing advanced prompting techniques, such as Chain-of-Thought or Few-Shot prompting
  • Experience with dialogue systems and context management
  • Hands on experience with LLM Orchestration Frameworks, such as LangChain / LangGraph
  • Experience with Transformer architectures, specifically understanding Attention mechanisms, Context Windows, and Tokenization constraints
  • Experience with SQL
