AI Engineer

We will count on you to:

• Run focused proofs-of-concept — typically one or two at a time — to evaluate emerging AI technologies against real Marsh use cases, moving from experiment to recommendation at speed
• Select and recommend technologies for adoption, producing clear guidance on when and why to use them
• Productionise chosen capabilities with repeatable, infrastructure-as-code deployment patterns using Crossplane across AWS, Azure, and other hyperscaler clouds, then hand operational ownership to the appropriate platform teams
• Direct AI coding agents (GitHub Copilot, Claude Code, Cursor, and others) — ensuring they are technically configured to leverage new technologies, select them appropriately, and follow Marsh standards
• Become a subject-matter expert in one or more AI technology domains (e.g. memory and retrieval, agent orchestration, guardrails and safety, MCP tooling) and coach peers across Marsh on those topics
• Engage with business units across Marsh through architecture forums, dev councils, and other channels to understand needs and feed requirements back into the PoC pipeline
• Share knowledge internally through blog posts, demos, and presentations — keeping the wider engineering community informed about what's coming and what's ready

What you need to have:

• Strong software engineering experience in Python and/or TypeScript, with a track record of shipping production systems — not just prototypes
• Hands-on experience with AI engineering: integrating, deploying, instrumenting, and operating LLM-based systems (prompt engineering, retrieval-augmented generation, function calling, agent frameworks, evaluation, observability)
• Experience writing infrastructure-as-code for cloud deployments (Crossplane preferred; Terraform, Pulumi, or CDK experience transfers well)
• Comfort working across multiple cloud platforms (AWS, Azure, GCP) rather than deep specialism in one
• Strong intellectual curiosity and high standards — you actively track emerging technology, learn quickly, and care about doing excellent work
• The ability to evaluate a new technology quickly and form a clear recommendation
• Excellent communication skills, able to explain a complex technical decision to both engineers and non-technical stakeholders

What makes you stand out:

• Breadth of programming language experience beyond Python/TypeScript — Rust, Go, or others that demonstrate curiosity and range
• Familiarity with Model Context Protocol (MCP) — building or consuming MCP servers and tools
• Experience with Crossplane or Kubernetes-based infrastructure management
• Exposure to AI safety and guardrails frameworks (content filtering, prompt injection defence, output validation)
• Experience configuring or extending AI coding assistants (custom instructions, tool integration, workspace configuration)
• Background in fine-tuning or adapting foundation models

What makes this role different:

• You'll use things before anyone else. Preview APIs, beta frameworks, technologies that don't have Stack Overflow answers yet.
• You'll shape technical direction. Your PoC outcomes and recommendations directly influence which technologies Marsh adopts across the enterprise.
• You'll onboard humans and machines. You'll ensure that AI coding agents across the organisation are configured to use the right tools in the right way.
• You'll be one of the first members of the AI CoE. You'll help shape ways of working, team culture, and technical standards as the team grows.
• You'll have the tools you need. Access to AI models, tools, tokens, and broader professional development opportunities.

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 collaborate 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.
