Enterprise cloud ERP for finance, HR, and workforce planning

Software Development Pleasanton, California 10,001+ employees Public Company

Workday is a 10,000+ person public SaaS company building cloud ERP for finance and human resources at scale—adopted by over 10,000 organizations including more than half the Fortune 500. The stack reveals a hybrid integration strategy: built on Java/AWS/GCP with REST/GraphQL APIs, but also deeply embedded with legacy connectors (Oracle, SAP, PeopleSoft, ADP) to replace those same platforms. Active adoption of Workday Data Cloud, LangGraph, and RAG signals a pivot toward AI-driven analytics and contract intelligence; hiring is sales-led (461 roles) with secondary engineering (260), reflecting a land-and-expand motion through implementation-heavy deployments.
