Full-Stack Engineer (Forward Deployed) - Digital Client Experience - Marsh

Marsh is hiring a full-stack engineer to join our Innovation & Applied AI team within the DCX initiative, focused on building a competitive digital platform. The team is 20 people, primarily based in London, and we’re looking for someone who can significantly increase productivity while adapting to new ways of working. You’ll have the opportunity to help build what we believe will become the largest data platform in the insurance industry and a sophisticated digital platform supporting renewal strategy.

We’re seeking strong AI technology skills and architectural understanding. For recent graduates, we’re looking for a business bachelor’s degree with a master’s in statistics, computer science, physics, or a related STEM field. For more experienced candidates, we’re looking for strong data foundations and a proven ability to apply AI at scale in real‑world, production environments. The ideal candidate is a versatile full‑stack data professional who thrives in complex, fast‑paced environments, combining deep technical expertise with strong business acumen in retail operations and insurance risk.

You’ll be a proactive problem solver and collaborative communicator who can turn ambiguous business challenges into robust, data‑driven solutions—using data to drive strategic risk management and insurance recommendations.

We will count on you to:

• Own features end‑to‑end—from data consumption and querying through API logic to client‑facing UI (minimal handoffs, high autonomy).
• Self‑source the data you need by navigating our data platform (e.g., Databricks/lakehouse patterns), writing SQL, and understanding upstream structures and quality.
• Build and operate scalable, secure pipelines and curated data layers that power risk analytics and insurance recommendations.
• Implement front‑end mathematical/actuarial computation with precision (e.g., exposure analysis, loss projections, premium/price‑impact calculations) and validate results.
• Develop backend services and APIs (TypeScript/Node; NestJS or similar) to support data access, computation, and model inference.
• Build modern React experiences (components, state, data visualisation) that explain insights and recommendations clearly to end users.
• Integrate AI into your delivery workflow (e.g., Copilot, code generation, automated testing) to increase quality and throughput.
• Build strong insurance/actuarial domain understanding to make product‑informed engineering decisions and translate ambiguous needs into working software.

What you need to have:

• Strong TypeScript/Node.js experience, including NestJS (or comparable frameworks) in production.
• Strong React skills (component architecture, state management) and experience delivering data‑heavy UIs.
• Strong SQL/data querying skills and the ability to self‑serve from Databricks or similar data platforms.
• Solid math/quantitative skills, comfortable implementing and validating actuarial/financial computations on the client side.
• Experience building APIs/services that connect data, computation, and user‑facing applications.
• High ownership and comfort working from ambiguous requirements, making sound decisions independently.
• Ability to learn quickly and build domain expertise in insurance/actuarial concepts.
• AI‑enabled development experience—using AI tools daily and shaping AI‑augmented engineering practices.

What makes you stand out?

• Experience with data visualisation libraries (D3, Recharts, AG Grid, etc.).
• Prior work on pricing, underwriting, exposure, claims, or risk analytics products.
• Familiarity with modern lakehouse/data engineering patterns and production reliability practices (testing, observability, performance).
