AI Architect

Location: Oaks

SEI is seeking an AI Architect. As part of the Enterprise AI team, you will be responsible for designing and delivering enterprise AI platforms-RAG systems, agentic frameworks, document intelligence services, and responsible‑AI patterns-on Azure. You bridge strategy and execution: defining reference architectures, running fast POCs, writing production code, and partnering with Info Sec, Cloud, and business stakeholders.

What you will do:

* Design AI architectures end‑to‑end: RAG pipelines, agentic orchestration (multi‑agent, tool use, MCP), retrieval strategies, grounding, and structured outputs.

* Architect Document Intelligence as a Service: ingestion, OCR/vision, extraction, verification, multi‑tenant design, and sensitive‑data handling.

* Define enterprise patterns: prompt governance, model routing, security envelopes, HITL gates, plugin/MCP integration, fallback/verification flows.

* Prototype fast: build rapid POCs in Python to validate architecture, derisk decisions, and accelerate delivery.

* Drive Trust

AI: hallucination testing, bias/fairness evals, lineage, scoring, drift monitoring, and compliance alignment.

* Design robust telemetry: retrieval/prompt tracing, eval feedback loops, guardrail instrumentation (Open Telemetry, Langfuse, App Insights).

* Interface with Info Sec & Cloud Enablement: private networking, identity boundaries, policy‑as‑code, DLP, model‑risk governance.

* Publish reference architectures, reusable modules, decision playbooks; lead design reviews and mentor engineers.

What we need from you:

* A minimum of 10 years of experience with software/ML engineering; strong Python (APIs, services, production).

* Deep RAG expertise: embeddings, hybrid search, chunking, reranking, evals, guardrails.

* Agentic AI: multi‑step agents, tool calling, orchestration frameworks (Lang Chain/Llama Index or custom).

* MCP / plugin patterns, tool‑server integration, context protocol design.

* Azure:
OpenAI/Models, AI Search, ML, AKS, Functions, Key Vault, VNET/private endpoints.

* Solid grasp of LLM lifecycle: prompting, structured outputs, token/cost management, fine‑tuning concepts.

* Ability to design for regulated industries: PII handling, isolation, audit, governance readiness.

* Strong communication; able to present to C‑suite, Info Sec, and engineering audiences.

What we would like from you:

* Experience effectively interacting with large application development and delivery teams and application development managers who are providing full lifecycle application support in complex, heterogeneous environments

* Experience working with senior leadership, ability to work comfortably with a wide range of people and skill sets

* LLM fine‑tuning (LoRA/QLoRA), evaluation frameworks (RAGAS, pairwise).

* Vector databases (Milvus, Pinecone, Weaviate).

* Trust

AI implementation: safety evals, governance dashboards, drift monitoring.

* Type Script/Node for plugins or front‑end integrations.

This team follows a hybrid schedule and work 3 days in the office.
