Design, agentic behaviour, and performance optimization are all inherent to the role, because the needs converge: architecture shapes behaviour, and behaviour determines what needs optimizing.\nWhat makes it interesting is what the agents have to do. Underwriting, claims, and the other core areas each involve multi-step workflows with real consequences, so agents need to reason over long context, follow complex instructions reliably, and integrate with systems of record that were never designed for them. Reliability is the hard part, and it is largely an evaluation problem rather than a prompting one.\nThis work is aimed at direct implementation. People on this team move between agentic work, systems engineering, and applied science as priorities shift. Less a multi-agent system than one generalist with broad tool access.\nMajor Responsibilities\nDesign and develop agentic systems end-to-end: agent loop design, orchestration, memory and state, tool integrations, and multi-agent workflows\n\nMake agents reliable: diagnose why a loop stalls, why a tool gets misused, or why behaviour drifts between runs, and design the guardrails that hold up under real traffic\n\nMeasure agent quality continuously rather than at demonstration time: evaluation sets that reflect real workflows, regression checks that catch behavioural drift, and analysis that explains a failure rather than only flagging it\n\nTune the tradeoffs that decide whether an agent is usable: latency, answer quality, and token cost, including the judgement of which to give up in a given workflow\n\nIntegrate agents with the systems and data they depend on, and carry them from prototype to something the business can rely on in production\n\n What You'll Bring\nDeep expertise in production Python, with strong working knowledge of current agent frameworks and protocols (Claude Agent SDK, deepagents, LangGraph, MCP, or equivalents)\n\nExperience building and debugging agentic systems in production, where failure modes are emergent rather than exceptions: loop instability, tool misuse, unbounded context growth, and non-determinism\n\nA feel for the performance envelope: where latency comes from in a multi-step agent, what a token budget buys, and how to trade quality against both\n\nEvaluation rigour, and the judgement to design measurement that holds up in a business environment rather than a demonstration\n\nFluency with agentic coding tools in your own workflow, such as Claude Code and Codex. The team is fully immersed in this way of engineering, and we expect it to be part of how you build rather than something reached for occasionally\n\nThe profile can come from either direction: a software engineer who has moved into AI systems, or an AI engineer with strong systems fundamentals. Either way we expect engineering discipline, meaning version control, tests, reproducibility, and code the next person can pick up\n\nStrong Preference Given To\nEvaluation and tracing tooling for agent behaviour (LangSmith, Weights & Biases, or custom solutions)\n\nDistributed and event-driven systems experience (Kafka or similar)\n\nRetrieval and memory system design for long-running agents\n\nFull-stack development experience integrating agents into user-facing applications\n\nAbout Chubb\nChubb is the world's largest publicly traded property and casualty insurer, with operations in 54 countries providing commercial and personal insurance, reinsurance, and life insurance to clients worldwide.\nWe're at the forefront of AI-driven transformation in insurance.
