About The Role As a Principal AI Full-Stack Engineer on the AI Platform team, you'll own the design, build, and operation of the agentic AI systems powering our core insurance products — architecting LLM inference chains, building production AI infrastructure, shipping full-stack features from model to UI, and setting technical direction for the team.



You should be as comfortable debugging a RAG recall failure in production as whiteboarding agent memory architectures with research or debating interaction patterns with design. Responsibilities Build agentic AI applications end-to-end — RAG pipelines, multi-agent orchestration, tool calling, workflows — and ship insurance agents that run in production. Design and optimize LLM inference chains: prompt engineering, structured outputs, fine-tuning (Lo RA/PEFT), evals, and observability. Stand up production-grade AI infrastructure: vector databases, semantic retrieval, model gateways, inference acceleration, and cost governance. Own full-stack delivery — frontend (React/Next.js), backend (Python/Type Script), cloud-native deployment (K8s/Serverless) — taking demos to policy volumes in the millions. Partner with actuarial, underwriting, and claims experts to turn domain knowledge into trustworthy, explainable, auditabl
