The AI Center of Excellence is a newly formed team with a singular mission: get emerging AI capabilities into the hands of Marsh engineers and business teams as fast as the technology landscape moves.\nWe're looking for an Architect who wants to shape how AI is adopted across a global enterprise. You'll own areas of the AI platform architecture end-to-end - evaluating emerging technologies, designing integration patterns between new AI capabilities and Marsh's existing systems, and building the reference architectures and standards that guide adoption at scale.\nThis is an architecture role, not a pure engineering role - but you'll need to get hands-on with the technologies you're evaluating. You'll test things yourself, form clear technical opinions, own the architecture recommendations in your domain, and work with technical leaders across the enterprise to get them approved and implemented.\nWe will count on you to:\nOwn areas of the AI platform architecture - design how AI capabilities fit together and integrate with Marsh's existing technology landscape, taking end-to-end ownership of your domain areas\n Drive technology evaluation - identify which emerging AI technologies (LLMs, memory systems, agentic frameworks, guardrails) should come up for the next proof-of-concept, and define what success looks like\nCollaborate on proofs-of-concept - work alongside a software engineer on focused PoCs, owning the architecture perspective: integration patterns, deployment topology, and how the technology fits the broader roadmap\nBuild and maintain reference architectures - own high-level integration diagrams, reference architectures, and technology radar documents that guide AI adoption across the business\nDocument architecture for humans and AI agents - produce architecture documentation in formats that are useful to both human engineers and AI coding agents\nPresent at architecture forums - present at and contribute to the agenda of Marsh's Architecture Council, Dev Council, and business unit forums\nNavigate the enterprise landscape - understand Marsh's existing enterprise architecture deeply enough to design integration patterns that work with where we are today, not just where we want to be\nCoach peers - share architectural thinking and domain knowledge with colleagues in the AI CoE, helping the team build collective expertise\nWhat you need to have:\nProfessional experience in a software engineering, architecture, or technical design role - with a track record of contributing to design decisions, not just implementing them\nExperience designing or contributing to system architecture - integration patterns, component decomposition, technology selection - in a professional setting\nUnderstanding of cloud-native architecture across multiple platforms (AWS, Azure, GCP)\nHands-on comfort with AI coding platforms and copilots (GitHub Copilot, Claude Code, Cursor, or similar) and the modern languages they support\nStrong intellectual curiosity and high standards - you actively track emerging technology, learn quickly, and care about doing excellent work\nStrong communication skills, able to present a technical recommendation to both engineers and senior stakeholders\nThe ability to evaluate a new technology quickly and form a clear architectural opinion\nWhat makes you stand out:\nExperience with AI/ML technologies in a professional context - integrating, deploying, or architecting systems that use LLMs, RAG, embeddings, or agent frameworks\n\nFamiliarity with enterprise architecture - understanding how large organisations structure their technology estates and manage technology change\nExperience with architecture documentation approaches that are ready for consumption by AI agents as well as humans\nCloud architecture certifications (AWS Solutions Architect, Azure Solutions Architect, or similar)\nExperience presenting at internal architecture forums, tech talks, or external conferences\nWhat makes this role different:\nYou'll work with preview-stage technologies. Beta APIs, emerging frameworks, technologies that don't have documentation yet.\nYou'll shape technical direction across Marsh. Your reference architectures and technology recommendations directly influence how AI is adopted across the business.\nYou'll design for humans and machines. Your architecture documentation needs to work for human engineers and for AI coding agents.\nYou'll be one of the first members of the AI CoE. You'll help shape ways of working, documentation standards, and team culture as the team grows.\nYou'll present to senior forums. Architecture Council, Dev Council, business unit leadership - you'll own agenda items, not just attend.\n You'll have the tools you need. Access to AI models, tools, tokens, and broader professional development opportunities.\nWhy join our team:\nWe help you be your best through professional development opportunities, interesting work and supportive leaders.\nWe foster a vibrant and inclusive culture where you can collaborate with talented colleagues to create new solutions and have impact for colleagues, clients and communities.\nOur scale enables us to provide a range of career opportunities.\nMarsh (NYSE: MRSH) is a global leader in risk, reinsurance and capital, people and investments, and management consulting, advising clients in 130 countries.
