We are building a layered AI intelligence system — a multi-layer agent architecture with a dynamic router, context engine, execution loop, verification layer, and eval feedback cycle. This system will be designed to handle long-horizon business tasks that cannot be accomplished in a single model inference.
As the AI Systems Architect, you will own the design of the entire system. You will decide how intelligence is structured across layers, how context flows between components, when the system routes to a human, and how failures feed back into improvement. You will set the standards the rest of the team builds to.
The router: the component that selects which role to invoke next — executor, planner, verifier, clarifier — based on current task state, risk level, and uncertainty
The context engine: RAG pipelines, structured memory, MCP tool connections, and the prompt library that gives the system company-specific knowledge
The execution loop: the action-observe-act cycle that lets the system pursue multi-step goals with real-world grounding
The verification layer: checker model design, confidence thresholds, and human escalation logic for irreversible actions
The eval loop: the feedback cycle that makes the system improve over time without retraining the base model
Deep understanding of how LLMs behave, fail, and can be steered through prompt design and context structure
Experience building and shipping multi-step agentic systems in production — not prototypes
Systems thinking: ability to design interfaces between components, reason about failure modes, and make architecture decisions that scale
Strong opinions about what does and does not work in LLM system design, backed by real experience
Comfort with ambiguity — this is a new field and there are no established playbooks
Experience with RAG architectures, vector databases, and retrieval systems
Familiarity with MCP, LangChain, LlamaIndex, or similar agentic frameworks
Background in distributed systems or backend infrastructure
Experience designing eval systems and benchmarks for LLM outputs
