This is not a ticket execution role. You get the problem and the context, you propose the solution, you build it, you ship it, and you defend the technical decisions directly in front of the client.
Responsibilities
Own end-to-end delivery: take a production LLM agent from requirement to production deploy, and defend the architecture and trade-offs directly with the client.
Build and harden agent orchestration (LangGraph / LangChain or equivalent) — routing, tool-calling, planning, synthesis, and state management.
Integrate tools over MCP and keep a growing tool surface fast and correct, including BM25, hybrid, or vector retrieval as scale demands.
Run models on AWS Bedrock and Bedrock AgentCore — model selection/routing, guardrails, memory, and regional residency profiles.
Build the evaluation harness (golden sets, LLM-as-judge, quality gates wired into CI) and instrument the system with OpenTelemetry for per-session token, cost, and latency attribution.
Drive down cost and latency with real levers (model routing, prompt caching, payload pruning, parallelizing independent calls) behind a regression gate; build in circuit breakers, fallbacks, and dead-letter handling.
Design and stage safe write-actions with least-privilege permissions, human-in-the-loop approval, plan versioning, audit trail, and rollback — released behind feature flags to a small cohort first.
