As an AI Engineer Intern, you'll join a global team of engineers and product professionals working on AI-enabled digital solutions transforming P&C insurance. This internship provides hands-on exposure to three core disciplines: applied AI/ML, production AI/LLM systems engineering, and agentic AI systems. You'll contribute to real projects across the AI product lifecycle, from model experimentation to production support, while learning from experienced engineers in a fast-paced enterprise environment. This position offers a unique opportunity to gain hands-on experience building production AI systems at enterprise scale while contributing to Chubb's AI-driven transformation.

We expect our AI engineers to be AI-native in how they work. You should be comfortable using AI-powered coding tools (e.g., GitHub Copilot, Cursor, Claude Code) and agentic development environments to accelerate your workflow, debug problems, and explore solutions.

Key Responsibilities

Applied AI/ML 

• Assist AI engineers in building and testing ML/AI solutions for business challenges in cloud environments
• Support experimentation with LLM techniques including prompt engineering, fine-tuning workflows, and evaluation methods
• Help curate and prepare datasets for model training and evaluation
• Write and maintain Python scripts for data processing, model inference, and pipeline automation

Production AI Systems 

• Contribute to building and testing AI service components including APIs, inference pipelines, and integration layers
• Assist with prompt management, versioning, and testing workflows
• Support documentation and testing of AI system integrations
• Learn production engineering practices including containerization (Docker), version control, and CI/CD workflows

Agentic AI Systems

• Explore agentic AI frameworks (e.g., LangChain, CrewAI, AutoGen) through guided prototyping projects
• Assist in testing agent behaviors, tool integrations, and multi-step workflows
• Support evaluation and observability efforts including prompt tracing and performance logging
• Document findings and contribute to internal knowledge sharing. 

General Engineering Practices

• Write clean, well-documented code following team standards and guidelines
• Participate in code reviews (as reviewer and reviewee) to develop engineering judgment
• Communicate progress, blockers, and learnings clearly to mentor and team
• Complete a capstone project demonstrating skills developed during the internship
