Tools you may use: Python, PyTorch, Hugging Face, vLLM, LangChain/LlamaIndex, FAISS/Pinecone/OpenSearch, Postgres, Redis, Docker, Terraform, GitHub Actions, MLflow/W&B, AWS (Bedrock, SageMaker, Lambda, S3, CloudWatch). You'll close the loop from voice-of-customer insight model/design choices launch telemetry and iteration, with success measured by outcomes like task completion, CSAT, time-to-resolution, and deflection rate-not just model scores.
