• Experience working with LLMs such as:
• OpenAI
• Anthropic
• Gemini
• Open-source LLMs
• Experience with prompt engineering and prompt optimization techniques
• Experience conducting LLM evaluations and measuring model performance
• Familiarity with:
• LangChain
• LangGraph
• LlamaIndex
• Semantic Kernel
• Experience with vector databases, embeddings, and RAG architectures
• Strong software engineering fundamentals, design patterns, and system design skills
• Excellent problem-solving and communication skills

Preferred Qualifications
