📋 Description

• Design and build conversational AI agents for returns, claims, and customer service experiences • Own agent systems from architecture → implementation → evaluation → production operations • Build RAG / context graph retrieval pipelines that ground agent responses in real company and customer data • Design agent orchestration for multi-step workflows that interact with identity, risk, order, and loyalty systems • Create evaluation frameworks to measure task completion, accuracy, safety, and user satisfaction • Implement guardrails and safety mechanisms — content moderation, hallucination detection, graceful fallbacks • Integrate conversational experiences across web, mobile, SMS, and email channels • Make real decisions around prompt design, model selection, latency/cost/quality tradeoffs, and failure modes • Collaborate with product, design, and ML teams to build systems that are technically sound and product-aware

🎯 Requirements

• Have shipped conversational AI or agent-based systems used by real users in production • Have built production systems on top of LLM APIs and agent frameworks — not just prompt playgrounds, but real integrations involving tool orchestration, context management, and reliability at scale • Have a point of view on model selection tradeoffs — when to use frontier APIs vs. open-weight models (Qwen, Llama, Mistral), and understand the cost, latency, privacy, and capability tradeoffs of each • Understand prompt engineering beyond basics: structured outputs, few-shot learning, chain-of-thought, tool calling • Have built context graph pipelines that go beyond naive retrieval — entity resolution, relationship modeling, and dynamic context assembly from structured and unstructured data • Have designed agent architectures that use function calling, tool execution, or multi-step reasoning • Have strong programming skills in Python or TypeScript • Have experience building and integrating APIs and backend services • Are comfortable reasoning about evaluation, safety, and reliability in non-deterministic systems • Take initiative naturally and are comfortable operating with ambiguity.
