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.We will count on you to:Own 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 areasDrive 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 likeCollaborate 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 roadmapBuild and maintain reference architectures — own high-level integration diagrams, reference architectures, and technology radar documents that guide AI adoption across the businessDocument architecture for humans and AI agents — produce architecture documentation in formats that are useful to both human engineers and AI coding agentsPresent at architecture forums — present at and contribute to the agenda of Marsh's Architecture Council, Dev Council, and business unit forumsNavigate 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 beCoach peers — share architectural thinking and domain knowledge with colleagues in the AI CoE, helping the team build collective expertiseWhat you need to have:Professional experience in a software engineering, architecture, or technical design role — with a track record of contributing to design decisions, not just implementing themExperience designing or contributing to system architecture — integration patterns, component decomposition, technology selection — in a professional settingUnderstanding of cloud-native architecture across multiple platforms (AWS, Azure, GCP)Hands-on comfort with AI coding platforms and copilots (GitHub Copilot, Claude Code, Cursor, or similar) and the modern languages they supportStrong intellectual curiosity and high standards — you actively track emerging technology, learn quickly, and care about doing excellent workStrong communication skills, able to present a technical recommendation to both engineers and senior stakeholdersThe ability to evaluate a new technology quickly and form a clear architectural opinionWhat makes you stand out:Experience with AI/ML technologies in a professional context — integrating, deploying, or architecting systems that use LLMs, RAG, embeddings, or agent frameworksFamiliarity with enterprise architecture — understanding how large organisations structure their technology estates and manage technology changeExperience with architecture documentation approaches that are ready for consumption by AI agents as well as humansCloud architecture certifications (AWS Solutions Architect, Azure Solutions Architect, or similar)Experience presenting at internal architecture forums, tech talks, or external conferencesWhat makes this role different:You'll work with preview-stage technologies. Beta APIs, emerging frameworks, technologies that don't have documentation yet.You'll shape technical direction across Marsh. Your reference architectures and technology recommendations directly influence how AI is adopted across the business.You'll design for humans and machines.
