Senior AI Engineer

Chubb is looking for a Senior AI Engineer to lead the design, development, and deployment of advanced generative AI solutions that improve how we operate across the insurance lifecycle — from underwriting and claims to customer service and risk assessment. This role sits at the intersection of software engineering, applied AI, and technical leadership, turning the latest LLM capabilities into reliable, production-grade systems built on our Azure and Databricks platform. As a senior member of the team, you will not only build high-quality AI solutions, but also help shape technical direction, guide architecture decisions, mentor other engineers, and influence how AI capabilities are delivered across the organization.

Key Responsibilities:

• Lead the design and build of end-to-end generative AI applications using LangGraph, including agentic workflows, RAG pipelines, and LLM-integrated services.
• Define and drive architecture for scalable, secure, reliable, and maintainable AI solutions deployed in production.
• Develop robust, well-tested backend APIs with FastAPI, containerized via Docker and deployed on Kubernetes.
• Architect and own search and retrieval solutions using Azure AI Search and MongoDB, including design of indexing strategies, hybrid search configurations, and retrieval evaluation.
• Work within our Azure cloud environment, integrating with Azure OpenAI, Azure services, and our broader data platform.
• Collaborate with product managers, data scientists, engineers, and other stakeholders to scope and deliver AI features that address real insurance business problems.
• Own the full software lifecycle, including design, code review, testing, deployment, monitoring, and production support.
• Translate complex business requirements into well-scoped technical solutions with a strong focus on reliability, maintainability, failure modes, and operational excellence.
• Mentor and support junior engineers through design reviews, code reviews, and technical guidance.
• Contribute to technical standards, best practices, and reusable patterns for AI engineering across the team.
• Evaluate and improve model quality, retrieval strategies, prompt and agent design, and production performance over time.
• Partner with business and technical leaders to shape AI roadmaps and identify high-impact opportunities for automation and decision support.

Qualifications

Desired Qualifications:

• 6+ years of software engineering experience, with strong fundamentals in system design, data structures, and clean code practices.
• Proven experience designing and shipping production-grade AI or ML-enabled software systems.
• Strong proficiency in Python, including building and shipping production backend services.
• Hands‑on experience building applications with LLMs such as Azure OpenAI, OpenAI, Anthropic, or similar.
• Experience with FastAPI or comparable Python web frameworks.
• Production experience with Docker and Kubernetes, including deployment and management on AKS.
• Strong hands‑on experience with Azure, including Azure OpenAI, Azure AI Search, AKS, and Databricks.
• Proven production experience with LangGraph and LangChain, including multi‑step agentic workflows and tool‑calling agents.
• Hands‑on experience with Azure AI Search or other vector/hybrid search solutions, including vector search, hybrid search, and retrieval evaluation.
• Experience with Databricks and PySpark for large‑scale data processing.
• Experience designing evaluation frameworks for LLM systems, including offline metrics, hallucination detection, and production monitoring.
• Experience implementing responsible AI practices in a regulated environment, including audit trails, confidence scoring, and human‑in‑the‑loop controls.
• Background in traditional ML or data engineering, including feature pipelines, model training, and ETL, is preferred.
• MongoDB or other NoSQL database experience is preferred.
• Prior exposure to insurance domain concepts such as underwriting, claims, and policy administration is preferred.
• Experience mentoring engineers, leading technical discussions, and influencing architecture decisions.

Preferred Attributes:

• Strong problem‑solving skills and the ability to work through ambiguity.
• Ability to balance speed of delivery with engineering quality and long‑term maintainability.
• Strong communication skills and the ability to explain technical concepts to both technical and non‑technical stakeholders.
• A proactive mindset with ownership of outcomes and continuous improvement.
• Interest in emerging AI technologies and practical application of LLMs in enterprise environments.

What Success Looks Like:

• You lead the delivery of high‑impact AI solutions that are reliable, scalable, and production‑ready.
• You help the team make better technical decisions through strong architecture and engineering judgment.
• You raise the quality bar through mentoring, code reviews, and engineering best practices.
• You contribute to a stronger AI engineering capability across the organization.
• Join Chubb as a Senior AI Engineer and play a key role in shaping the future of intelligent, scalable, and enterprise‑ready AI solutions that create real impact across the insurance lifecycle.
