About WTW

WTW provides data-driven solutions across three domains: people (employee benefits, HR consulting, pensions), risk (management and mitigation), and capital (financial strategy and optimization). The client base spans enterprise employers and institutional investors across 140 markets. Delivery is split between traditional consulting services and software-enabled platforms (ServiceNow, Epic Systems for pensions and benefits administration). The sales-heavy department mix (272 roles) reflects a consulting business model; healthcare and support teams (111 and 89 roles respectively) underscore focus on benefits and occupational health verticals. Active project work includes group medical and benefits design, total rewards strategy, and vendor optimization, with persistent friction around bid processes, new client acquisition, and cross-selling into existing accounts.
