Marsh operates a sprawling professional-services footprint—90,000+ colleagues across four divisions (Marsh Risk, Guy Carpenter, Mercer, Oliver Wyman) advising on risk, strategy, and people. The tech stack is heavy on Microsoft Office + SQL Server + cloud (AWS, Azure), with active projects spanning LLM-powered code review, multinational client reporting, and new product development. Sales hiring dominates (29 open roles), but the challenge set reveals operational friction: compliance, workflow optimization, and scaling expertise across a geographically distributed org.
