Chubb is making strategic investments in artificial intelligence to fundamentally change how we assess risk, serve customers, and operate our business. Combining cutting-edge AI capabilities with our exceptional financial strength, comprehensive product portfolio, and global reach, we're building the future of intelligent insurance solutions.

The Role

As a Senior AI Engineer, you'll work with a global team of engineering and product teams to implement state-of-the-art AI-enabled digital solutions transforming P&C insurance globally. This position spans three core disciplines: applied AI/ML, production AI/LLM systems engineering, and agentic AI systems offering the opportunity to work across the full AI product lifecycle from model development to production deployment.

Major Responsibilities

• Work closely with AI engineers and product teams to design, build, and deploy ML/AI solutions solving complex business challenges in cloud environments (CPU & GPU)

• Research & implement state-of-the-art LLM techniques including post-training (e.g., SFT, GRPO, RLHF), prompt engineering, and evaluation frameworks

• Build production AI services including middleware, prompt management layers, inference pipelines, LLM-Ops tooling, and async messaging systems (e.g., Kafka) for model integration into applications

• Design and develop agentic AI systems end-to-end from orchestration frameworks (LangChain, CrewAI, AutoGen) to memory/data layers, tool integrations, and multi-agent workflows

• Implement observability, monitoring, and evaluation for production AI systems including prompt tracing, agent behavior analysis, and performance metrics

• Build reusable pipelines, processes, and tools to streamline AI/ML workflows from development to production

• Ensure high-quality, maintainable code that meets business objectives, quality standards, and development guidelines

• Manage stakeholder expectations and communications while adapting to shifting priorities

Must Have:

• 5+ years' experience in Machine Learning/AI Engineering/Software Engineering/Data Science with deep expertise in production Python development

• Strong knowledge of ML frameworks and libraries (Transformers, trl, PyTorch, LangChain, LlamaIndex, or similar)

• Experience building distributed, high-throughput, low-latency systems

• Experience with containerization and orchestration technologies (Kubernetes, Docker)

  Strong Preference Given To:

• Experience with the full LLM lifecycle: dataset curation, pos-training, evaluation, data labelling and management, and deployment

• Production AI systems experience: building APIs, middleware, prompt management, inference optimization, or LLM-Ops infrastructure

• Agentic AI development: building autonomous agents, multi-agent systems, memory/state management, tool use, or agent evaluation frameworks

• Experience with observability/monitoring tools for AI systems (LangSmith, Weights & Biases, custom tracing solutions)

• Understanding of system architecture design and technical feasibility tradeoffs

• Full-stack development experience integrating AI into user-facing applications

• P&C insurance domain knowledge
