• Architect solutions for high-value insurance use cases (claims intake automation, submission triage, document intelligence, underwriting copilots, policy Q&A, contact-center copilots).
• Design RAG systems at scale: chunking strategies, embeddings, vector stores, retrieval tuning, and grounding to reduce hallucination.
• Design multi-agent and tool-calling workflows that automate complex insurance processes.
• Set LLMOps and quality standards: prompt engineering, evaluation, guardrails, monitoring, versioning, and cost/latency optimization.
• Apply responsible AI governance: hallucination controls, PII handling, bias mitigation, explainability, auditability, and regulatory compliance (NAIC, GDPR, EU AI Act).
• Oversee integration with core insurance platforms (Guidewire, Duck Creek, Sapiens) and enterprise data/content systems.

Leadership & Communication

• Serve as a senior technical authority and trusted advisor to client stakeholders and program leadership.
• Translate complex GenAI concepts, tradeoffs, and risks into clear, persuasive narratives for non-technical and senior audiences.
• Craft and deliver compelling presentations and demos that build client confidence.
• Align diverse stakeholders (business, IT, risk, compliance) around a shared architecture and delivery approach.
• Manage, mentor, and grow a team of architects and GenAI engineers; uphold technical standards and build capability.

Skills and attributes for success

• Skills required Strong executive presence; comfortable influencing senior client stakeholders.
• A clear communicator who turns technical complexity into clarity and momentum.
• Hands-on delivery leadership; thrives on owning complex engagements end to end.
• Commercially minded and outcome-focused.

• Experience in technology, with a strong track record delivering complex enterprise programs and 2+ years delivering production generative AI initiatives.
• Demonstrated experience owning architecture and delivery of enterprise-grade systems in production.
• Deep, hands‑on experience with LLMs (OpenAI, Anthropic, Google, or open‑weight models like Llama/Mistral) and orchestration frameworks (LangChain, LlamaIndex, Semantic Kernel, or equivalent).
• Proven expertise in RAG design, embeddings, and vector databases (Pinecone, Weaviate, pgvector, Azure AI Search).
• Experience with agentic architectures, function/tool calling, and structured outputs.
• Strong prompt engineering, evaluation, and LLM guardrail/safety experience.
• Experience with cloud GenAI platforms (Azure OpenAI, AWS Bedrock, Google Vertex AI) and LLMOps tooling.
• Solid understanding of scalable system design, API design, enterprise integration patterns, and secure handling of sensitive data.
• Strong grasp of responsible AI, model governance, and emerging AI regulation.
• Excellent communication and storytelling skills, able to make complex concepts accessible to senior, non-technical audiences.

The following will be an advantage;

• Desired Criteria Experience delivering GenAI solutions in insurance or broader financial services.
