  • 2+ years of experience in an engineering role

  • Deep understanding and practical experience with core Generative AI concepts and techniques, including embedding models, Retrieval Augmented Generation (RAG), attention mechanisms, and similarity search
  • Strong Python development experience writing clean and maintainable code
  • Ability to learn low level topics, such as protocols (HTTP) and Windows internals, to then implement in code
  • Clear thinker and efficient communicator (i.e. written and verbal).
  • Go-getter attitude and can work independently
  • Able to take high level requirements and lead the project to completion
  • The ability to work remotely with teammates across the organization and maintain healthy working relationships.
