Job Overview Job Overview

We're hiring an AI Architect to design and govern the end-to-end architecture for AI solutions spanning multi-agent orchestration, knowledge-graph reasoning, retrieval-augmented generation (RAG), and evaluation at scale. You will define model strategy, reasoning patterns, data interfaces, and safety / guardrails; establish reusable blueprints; and partner with engineering, security, and data teams to deliver reliable, explainable, and cost-effective AI capabilities.

Key Responsibilities

• AI Architecture & Patterns : Define reference architectures for LLM-powered systems (planner / reasoner, router / composer, tool / connector mesh), including typed I / O contracts and failure isolation.
• Knowledge & Retrieval Strategy : Architect coexistence of Knowledge Graph reasoning and RAG baselines; select embedding / vector stores, chunking, retrieval / reranking, and subgraph / query patterns.
• Model Strategy & Routing : Establish model selection policies (small→large escalation), prompt / adapter patterns, caching, and cost / latency budgets; document routing outcomes.
• Evaluation & Quality Gates : Design test sets and scoring rubrics (faithfulness / correctness, precision / recall, multi-hop coverage, latency); implement automated re-evaluation on any change (model / agent / prompt / data).
• Safety & Guardrails : Specify policy-as-code, entitlement checks (role / row / column), PII / PHI handling, and content moderation; define red-team tests and jailbreak defenses.
• Data & Interfaces : Define schemas for AI inputs / outputs; guide ontology / taxonomy alignment; ensure provenance / lineage for KG / RAG pipelines; minimize data movement.
• Operability & Observability : Standardize tracing / logging / metrics for AI runs (call graphs, token / latency / cost); set SLOs and error budgets; partner with DevOps for CI / CD and environment promotion gates.
• Technical Leadership : Review designs / PRs; mentor AI engineers; communicate decisions / trade-offs to stakeholders; maintain decision records and roadmaps.
