  • • 1+ year of hands-on experience with LLMs (e.g., OpenAI GPT series, Llama, Gemini)
  • • Proficiency in at least one programming language (Python, JavaScript/TypeScript)
  • • Familiarity with prompt engineering techniques (few-shot, chain-of-thought, structured outputs, function calling)
  • Desired Qualifications
  • • Strong, data-driven problem-solving skills
  • • Strong written and verbal communication skills
  • • Exposure to RAG concepts, embeddings, and vector databases
  • • Understanding of AI safety considerations (prompt injection, bias, data privacy)
