Lead ML Engineer

Job Description

The Role

This is a senior, hands-on engineering leadership role responsible for turning pricing, portfolio and underwriting models into robust, production-grade capabilities embedded within operational workflows and core systems (e.g., PAS platforms such as Duck Creek, EXP).

You will define and implement the standards, patterns and architecture that ensure analytics solutions are scalable, monitored, auditable and commercially durable — across a portfolio of pricing, conversion and risk models serving Commercial Insurance across EMEA.

You will be the most senior technical practitioner in the analytics and AI team, responsible for setting the engineering bar and raising capability across a growing but junior-heavy squad. This is not a research or experimentation role. It is a build-and-scale role.

What You Will Join

You will join the EMEA Data, Analytics & AI team at Chubb — one of the world’s largest commercial insurers. The team delivers data, analytics and AI capabilities across Commercial Insurance in EMEA.

You will work alongside data scientists, data engineers, actuaries and underwriters — translating analytical models into production capabilities that directly impact commercial outcomes.

Why This Role Matters

This is not a support function. The models this team builds directly influence which risks Chubb underwrites, how they are priced, and how the portfolio is managed. Getting them into production reliably — and keeping them there — is a commercial priority, not a technical nice-to-have.

Core Responsibilities

• Production-Grade ML & AI Deployment (Primary Accountability)
• Design and implement scalable deployment patterns for ML models (batch and API-based scoring)
• Establish model lifecycle standards: versioning, retraining triggers, monitoring, documentation

• Proven experience in data science, ML engineering, or analytics engineering — with a clear trajectory toward production systems
• Proven experience deploying ML models into production — batch and/or real-time scoring in commercial environments
• Experience integrating analytics into operational workflows — not just dashboards, but embedded decision support
• Experience designing and operating model monitoring frameworks — drift detection, performance tracking, alerting
• Strong Python ecosystem expertise — production-quality code, not notebook-only
• Experience with ML lifecycle tooling — MLflow, Azure ML, SageMaker or equivalent
• Cloud platform experience — Azure preferred
• Experience working in regulated industries — insurance or financial services strongly preferred
  
  

Desirable

• Experience with insurance platforms (Duck Creek, Guidewire, Acturis)
• Experience with pricing or actuarial model deployment
• Familiarity with CI/CD for ML (MLOps pipelines, automated testing, model registries)
• Experience leading or mentoring junior engineers and data scientists
• Exposure to GenAI / LLM deployment in enterprise settings
