At EY, we’re all in to shape your future with confidence.

We’ll help you succeed in a globally connected powerhouse of diverse teams and take your career wherever you want it to go.

Join EY and help to build a better working world.

The opportunity

We are seeking a Manager, AI Architect specializing in generative AI to lead the design and delivery of GenAI solutions for our clients. This is a hands‑on delivery and technical management role: you will own the architecture of a defined solution area or workstream, lead a small delivery team, and ensure your solutions run reliably in production. You will work closely with client teams and communicate technical decisions clearly to project stakeholders.

Your key responsibilities

Design and Delivery of Engagements

• Own the architecture and technical delivery of a GenAI solution area or workstream, from design through production rollout.
• Lead a small cross‑functional delivery team (engineers, data specialists) through the delivery lifecycle.
• Ensure solutions are scalable, secure, resilient, and cost‑aware in production.
• Manage delivery execution: architecture decisions within scope, technical risks, dependencies, quality checks, and blocker resolution.
• Apply engineering standards, reusable frameworks, and accelerators to improve delivery quality and speed.
• Take accountability for delivery quality, timelines, and outcomes within your workstream.

Technical Direction

• Design generative AI solutions: LLM selection, RAG pipelines, prompt orchestration, agentic workflows, and integration.
• Build solutions for insurance use cases (claims intake automation, submission triage, document intelligence, underwriting copilots, policy Q&A, contact‑center copilots).
• Design and tune RAG systems: chunking, embeddings, vector stores, retrieval tuning, and grounding to reduce hallucination.
• Implement multi‑agent and tool‑calling workflows that automate insurance processes.
• Apply LLMOps and quality practices: prompt engineering, evaluation, guardrails, monitoring, versioning, and cost/latency optimization.
• Apply responsible AI practices: hallucination controls, PII handling, bias mitigation, explainability, and compliance (NAIC, GDPR, EU AI Act).
• Support integration with core insurance platforms (Guidewire, Duck Creek, Sapiens) and enterprise data/content systems.

Leadership & Communication

• Act as a technical point of contact and advisor to client project stakeholders.
• Translate GenAI concepts, tradeoffs, and risks into clear explanations for technical and business audiences.
• Prepare and deliver clear presentations and demos to project stakeholders.
• Coordinate across business, IT, and compliance stakeholders on solution decisions.
• Guide and mentor junior engineers and consultants; help uphold technical standards.

Skills and attributes for success

• Hands‑on ownership of solution design and delivery.
• Clear communication with technical and business stakeholders.
• A collaborative, mentoring mindset with a small team.
• Outcome‑focused and quality‑driven.

To qualify for the role;

• Bachelor’s or Master’s in Computer Science, Engineering, or a related field.
• Experience in technology, including hands‑on delivery of enterprise solutions and delivering production generative AI initiatives.
• Hands‑on experience with LLMs (OpenAI, Anthropic, Google, or open‑weight models like Llama/Mistral) and orchestration frameworks (LangChain, LlamaIndex, Semantic Kernel, or equivalent).
• Practical expertise in RAG design, embeddings, and vector databases (Pinecone, Weaviate, pgvector, Azure AI Search).
• Experience with agentic architectures, function/tool calling, and structured outputs.
• Solid prompt engineering, evaluation, and LLM guardrail/safety experience.
• Experience with cloud GenAI platforms (Azure OpenAI, AWS Bedrock, Google Vertex AI) and LLMOps tooling.
• Good understanding of system design, API design, integration patterns, and secure handling of sensitive data.
• Working knowledge of responsible AI and model governance.
• Strong communication skills, able to explain complex concepts clearly.

The following will be an advantage;

• Experience delivering GenAI or AI/ML solutions in insurance or financial services.
• Familiarity with insurance core platforms (Guidewire, Duck Creek, Sapiens) and document‑heavy workflows (ACORD forms, loss runs, policy documents).
• Experience taking GenAI solutions from proof‑of‑concept toward production.
• Relevant cloud or AI certifications.
