About this role JLL is looking for a Platform Engineer to own the implementation and ongoing support of integration, workflow configuration, system administration, and UI/UX work across our Omnea procurement orchestration platform. Omnea implementation is kicking off in Q4 2026 supporting our procurement and finance function workflows and integrating with upstream and downstream systems such as Aravo and PeopleSoft to improve user experience. This role will lead the design and delivery of new integrations connecting Omnea to PeopleSoft, ePro, Aravo, and several other systems over time. Beyond integration delivery, this role will take on operational ownership of the technical enhancement and support aspects of Omnea once the tool is in BAU. Responsibilities Design, build, and maintain integrations between Omnea and Aravo, Peoplesoft, ePro, and additional tools over time Deliver successful technical implementation of Omnea. Own the technical design, data mapping, and validation logic for each integration, including error handling and reconciliation processes. Serve as the technical owner for Omnea, managing change management processes, configurations, workflows, UX/UI, audits, and the relationship with business stakeholders. Partner with stakeholders across Sourcing & Procurement, Finance, and Procurement to gather requirements and translate them into integration designs, balancing business needs against platform scope and maintainability. Ensure new integrations align with Omnea's configuration structure and data model, and with JLL's broader integration architecture and standards. Collaborate with the Enterprise Data Platform (EDP) team on integration architecture and design consistency. Troubleshoot integration issues and data discrepancies, coordinating with platform owners across connected systems on root cause and resolution. Develop and maintain technical documentation, including data flow diagrams, mapping specifications, and support runbooks. Build and execute test plans for integration changes tied to Omnea releases and related system releases.

Identify and recommend opportunities for continuous improvement across the integration landscape. Required Skills, Experience & Knowledge Real experience building and maintaining system-to-system integrations (API, file-based, or middleware) in an enterprise environment. Working knowledge of Omnea, Aravo, PeopleSoft, Yardi, Jaggaer or similar procurement/AP-adjacent systems — prior hands-on exposure to any of these is a strong plus. Comfort operating within a formal change management process and familiarity with SOC audit expectations. Strong stakeholder management — this role sits between technical delivery and business/finance relationships, and needs to hold the line on scope when it's warranted. High attention to detail; mistakes here touch supplier payments and compliance data. Able to work independently across multiple concurrent integrations, escalating real gaps rather than needing day-to-day direction. Comfortable working with AI tools (Claude or similar) to support daily tasks — documentation, requirements analysis, testing, and …
