Job Overview
Job Overview
We're hiring an Enterprise Architect to define and govern the technical blueprint for an AI-first, data-centric platform. The role spans target architecture, reference patterns, and guardrails across orchestration, knowledge systems, retrieval pipelines, security, and operations. You'll partner with product, security, data, and engineering leads to translate business outcomes into resilient, scalable designs-then guide teams to deliver them with measurable quality, cost, and reliability.
Key Responsibilities
Target Architecture &
Roadmap:
Define the end-to-end architecture (experience, orchestration, agents/tools, data/knowledge, security, observability) and a phased roadmap.
Reference Patterns & Standards:
Establish patterns for multi-agent orchestration, connector/adapter design, model routing, policy-as-code, and evaluation/observability; produce reference implementations.
Knowledge & Retrieval:
Architect the coexistence of knowledge graph reasoning and retrieval (RAG) baselines; select graph/embedding stores, query patterns, and caching strategies.
Integration & Platform Services:
Define typed interfaces and contracts for AI engines, vector/graph stores, SQL/warehouse, and external tools; standardize retries, idempotency, and failure isolation.
Security & Governance:
Embed SSO/IDP, secret management, entitlement models (role/row/column), data minimization, auditability, and red-team controls into the design.
Evaluation & SLOs:
Institutionalize quality gates (faithfulness/correctness, precision/recall, latency), automated re-evaluation on change, and service SLOs with error budgets.
Operability:
Drive choices for tracing/logging/metrics, incident response, capacity planning, and cost/performance budgets; ensure CI/CD, IaC, and environment promotion gates.
Technical Leadership:
Review designs/PRs, mentor leads, resolve cross-team trade-offs, and communicate architecture decisions to technical and non-technical stakeholders.
Required Skills
Architecture Mastery: 3-5+ years designing distributed systems or platforms (microservices, event-driven, API-first) on cloud environments.
AI/LLM Platform Patterns:
Practical experience with multi-agent orchestration, model/embedding selection, RAG pipelines, and knowledge graph solutions.
Data & Knowledge Stores:
Hands-on with one or more: graph DBs (RDF/SPARQL or property graph/Gremlin), vector DBs (pgvector, Milvus, Pinecone, Weaviate), SQL/warehouse.
Security-by-Design: SSO/OAuth/OIDC, secrets management,…
