Candidates should demonstrate hands-on experience with several of the following:

• OpenAI API
• Anthropic Claude API
• Google Gemini API
• Meta Llama models
• Model Context Protocol (MCP)
• Retrieval-Augmented Generation (RAG)
• Vector databases (Pinecone, Weaviate, Milvus, ChromaDB, pgvector)
• AI Agents and multi-agent frameworks
• LangChain, LangGraph, LlamaIndex, or equivalent AI orchestration frameworks
• Function calling and tool integration
• Prompt engineering and evaluation
• Embeddings and semantic search
• Streaming AI responses
• AI observability and monitoring
• API integrations with third‑party platforms (Stripe, Twilio, Firebase, Auth0, SendGrid, etc.)

Preferred Qualifications

• Experience building AI-native products.
• Experience with event-driven architectures.
