• Working experience with cloud platforms; deep expertise in AWS.
• Strong Python skills and experience with AI frameworks like Hugging Face Transformers, LangChain, and PyTorch.
• Beyond “RAG/fine-tuning”: require experience with RAG architecture patterns (chunking, hybrid search, reranking, citations, source attribution); Evaluation frameworks (e.g., automated retrieval eval, hallucination checks, regression testing); Safety/guardrails (prompt injection defenses, content filtering, PII redaction).
• Experience with high-performance inference (vLLM/TensorRT-LLM where applicable), batching, quantization, and GPU cost/perf tradeoffs.
• Designing multi-model routing and cost controls (fallbacks, caching, budget ceilings).
• Require competence in: data modeling, data quality checks, schema evolution, and governance.
• Vector DB + embedding ops: index management, re-embedding strategies, retrieval tuning.
• CI/CD for ML, model registry, feature stores, monitoring (drift + performance).
• Ability to define engineering standards (linting, type checking, testing strategy, code review norms) and enforce via CI.
• Threat modeling for GenAI (prompt injection, data exfiltration), privacy-by-design, retention policies, and auditability.
