• Agentic Orchestration:
  Design and deploy multi-agent systems using frameworks like Lang Graph or CrewAI, enabling autonomous task planning and tool-use (Function Calling).
• Enterprise-Grade Evaluation:
  Build "LLM-as-a-judge" frameworks and robust eval pipelines to measure hallucination rates, groundedness, and safety.
• Inference Optimization:
  Implement high-throughput, low-latency serving strategies including quantization, speculative decoding, and prompt caching.

• Typically requires 8+ years of overall software engineering experience.
• Core AI:
  Expert-level mastery of Transformers, attention mechanisms, and the latest frontier models (GPT-4o, Claude 3.5, Llama
  3).
• The Stack:
  Deep experience with vector databases (Pinecone, Weaviate, Milvus), orchestration layers (Lang Chain, Llama Index), and MLOps tools.
