  • Serve as the primary subject matter expert (SME) for Generative AI and Machine Learning within the team

  • Gather requirements and learn from the team on offensive security techniques

What You'll Need:

  • 2+ years of experience in an engineering role

  • Proven experience designing and implementing generative AI applications utilizing LLMs, either professionally or on your own

  • 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.

Bonus Points:
