Integration lead — Aravo and Supplier Platforms

JLL is seeking an Integration Lead for Aravo, its supplier management platform, which is live globally and supports its Workplace Management business. The role connects Aravo to PeopleSoft, Trustpair, Ingenious, Omnea, Yardi, Avetta and ISN, and completes phase two of the Aravo-to-Corrigo integration for certificates of insurance. The leader sees how these pieces fit together, leads the design of each integration, brings together engineers, vendors and business teams, and ensures releases are accurate, supported and ready for audit. The role works with JLL engineers and vendor teams rather than managing them, and is an integration leadership role, not a software development position. The role partners with Sourcing and Procurement, Finance and Accounts Payable. This position is on-site in Chicago, IL and does not provide visa sponsorship.
