AI/ML Engineer

Deploys and fine-tunes AI models for production use. Builds RAG pipelines, implements prompt engineering, creates evaluation frameworks, and optimizes inference costs. Works with OpenAI, Anthropic, and open-source models. ## Specialty LLMs, RAG, fine-tuning, prompt engineering, embeddings, vector databases ## When to Use AI feature implementation, model deployment, RAG system design, inference optimization ## Acceptance Criteria 1. Model accuracy meets specified threshold on evaluation set 2. Inference latency < target SLA 3. Cost per query within budget ceiling 4. RAG pipeline retrieves relevant documents with >= 90% precision 5. Prompt injection defenses validated 6. Model versioning and rollback capability demonstrated
