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

## Company: Marsh ## Description: **Full-Stack Engineer (Forward Deployed) — Digital Client Experience - Innovation & Applied AI - Marsh** Marsh is hiring a Full-Stack Engineer to join our Innovation & Applied AI team within the DCX initiative, focused on building a market-leading digital platform. DCX operates like a start-up within Marsh: a small, high-calibre team with the pace and autonomy of a start-up, backed by the scale, reach, and data advantage of a global leader. This is an opportunity to drive meaningful transformation across a major enterprise, solving complex problems with high visibility and outsized impact. Our team is around 20 people, primarily based in London. We are looking for engineers who thrive in fast-moving environments and raise the pace and quality of execution. You will help build what we believe will become one of the largest data platforms in the insurance industry, alongside a sophisticated digital platform supporting renewal strategy, risk insight, and better client outcomes. This is a hybrid role primarily based in New York aimed at **mid-to-senior engineers** who can operate independently from day one and work closely with product, business, and technical leaders, though exceptional early-career candidates will also be considered. We are looking for a **forward-deployed, AI-fluent engineer** with strong judgment: someone who can work directly with users, quickly get to the heart of a problem, and turn it into a practical technical solution. You should be excited by the AI frontier, testing new models, tools, and workflows early and applying the ones that create real value. **We will count on you to:** * Own features end-to-end - from data consumption and querying through API logic to client-facing UI, with minimal handoffs and high autonomy. * Work directly with users and business stakeholders, joining calls, understanding pain points first-hand, shaping solutions collaboratively, and owning delivery through to measurable impact. * Self-source the data you need by navigating our data platform, writing SQL, understanding upstream structures, and working confidently with Databricks or similar lakehouse patterns. * Build and operate scalable, secure pipelines and curated data layers that power analytics, risk insights, and insurance recommendations. * Implement front-end mathematical computations with precision, including exposure analysis, loss projections, premium calculations, and price-impact modelling. * Develop backend services and APIs using TypeScript/Node.js, NestJS, or similar frameworks to support data access, computation, and model inference. * Build modern React experiences, including components, state management, and data-rich interfaces that explain insights and recommendations clearly to end users. * Integrate AI into your engineering workflow using tools such as Copilot, code generation, automated testing, and AI-assisted development practices to improve speed, quality, and throughput. * Stay on the frontier of AI - when a new model drops, a new harness appears, or a better workflow emerges, assess it early, experiment quickly, and bring the best ideas into user and client experiences where they create clear business value. * Build strong insurance and actuarial domain understanding so you can make product-informed engineering decisions and translate ambiguous needs into robust, production-ready software. **What you need to have:** * Strong experience in TypeScript/Node.js, including NestJS or comparable backend frameworks used in production. * Strong React skills, including component architecture, state management, and experience delivering data-heavy user interfaces. * Strong SQL and data querying skills, with the ability to self-serve from Databricks or similar data platforms. * Solid mathematical and quantitative skills, with the ability to implement and validate computations accurately. * Experience building APIs and services that connect data, computation, and user-facing applications. * High ownership, sound judgment, and comfort working from ambiguous requirements with minimal oversight. * Confidence working directly with users and stakeholders to understand problems and shape practical solutions. * Ability to learn quickly and build domain expertise in insurance, risk, and actuarial concepts. * AI-native development experience, with a track record of using AI tools daily, shaping AI-augmented engineering practices, and staying current with the fast-moving frontier of models, tooling, and techniques. **What makes you stand out?** * Experience with data visualisation including libraries such as D3, Recharts, or AG Charts. * Experience building and shipping internal tools, automations, or AI-enabled workflows that delivered measurable business impact. * Prior work on pricing, underwriting, exposure, claims, or risk analytics products. * True full-stack range - comfortable moving from DevOps and data architecture through backend systems and complex logic to polished frontend delivery. * Familiarity with modern lakehouse or data engineering patterns and strong production practices across testing, observability, and performance. * Experience working in high-autonomy, startup-style environments where speed, judgment, and adaptability matter. * Experience working in highly embedded, user-facing engineering roles. * Ability to communicate clearly with non-technical stakeholders and frame technical work in business terms. * Academic depth in Computer Science or another STEM field, with additional business exposure a plus. **Why join our team:** * We help you be your best through professional development opportunities, interesting work and supportive leaders. * We foster a vibrant and inclusive culture where you can work with talented colleagues to create new solutions and have impact for colleagues, clients and communities. * Our scale enables us to provide a range of career opportunities, as well as benefits and rewards to enhance your well-being.
