Platform Engineer — Aravo Integrations

JLL empowers you to shape a brighter way . Our people at JLL are shaping the future of real estate for a better world by combining world class services, advisory and technology for our clients. We are committed to hiring the best, most talented people and empowering them to thrive, grow meaningful careers and to find a place where they belong. Whether you’ve got deep experience in commercial real estate, skilled trades or technology, or you’re looking to apply your relevant experience to a new industry, join our team as we help shape a brighter way forward. About This Role JLL is seeking a Platform Integration Engineer to own the complete integration lifecycle — design, build, UAT, and deployment — across our Aravo supplier management platform. Aravo is live globally supporting our Workplace Management business, and this role will lead the end-to-end delivery of new integrations connecting Aravo to systems including PeopleSoft, Trustpair, Ingenious, Omnea, Yardi, Avetta, and ISN, along with phase 2 of our Aravo-to-Corrigo integration for Certificates of Insurance. This is a SaaS integration delivery role, not a software development position. You will own the full integration lifecycle — from requirements gathering through production deployment — using platform-native APIs, file-based integration tools, and middleware to connect enterprise systems. You'll configure integrations, design data mappings, execute UAT with business stakeholders, and manage production deployments through formal change management processes. Beyond integration delivery, this role includes operational ownership of Trustpair on behalf of JLL Technology — managing change requests, SOC audit responses, and stakeholder relationships. This is a highly visible, cross-functional role partnering with Sourcing & Procurement, Finance, and Accounts Payable to shape how our supplier and vendor systems work together. What You'll Own: The Complete Integration Lifecycle Design (Requirements → Technical Specifications) Partner with business stakeholders to gather integration requirements and translate them into technical designs Design data flows between Aravo and connected systems, defining field mappings, transformation logic, validation rules, and error handling Create technical specifications including data mapping documents, API endpoint configurations, file format definitions, and integration architecture diagrams Ensure designs align with JLL's integration standards and platform capabilities Balance business needs against technical feasibility — know when to push back on scope that creates maintenance challenges Build (Configuration & Implementation) Configure integrations using platform-native tools, APIs (REST/SOAP), file-based transfers (CSV/XML/JSON), or middleware platforms Set up API connections: authentication, endpoint configuration, request/response formatting, and error handling Build file-based integrations: define file formats, field mappings, transformation rules, and automated file transfers (SFTP, AWS S3) Configure middleware workflows (if using MuleSoft, Dell Boomi, Workato, or similar tools) to orchestrate data movement between systems Implement data validation and reconciliation logic to ensure accuracy and consistency This is platform configuration work, not custom software development — you'll use SaaS admin consoles, integration tools, and low-code/no-code platforms UAT (Testing & Validation) Develop comprehensive test plans covering happy paths, error scenarios, data validation, and edge cases Execute end-to-end testing: validate data accuracy, verify transformations, test error handling, and confirm system behavior Coordinate UAT with business stakeholders: schedule testing sessions, provide test data, document results, and track defects Perform data reconciliation between source and target systems to ensure 100% accuracy Document test results, create defect reports, and manage issue resolution with platform owners Sign off on UAT completion before moving to production deployment Deploy (Production Release & Go-Live) Prepare deployment packages including configuration files, API credentials, runbooks, and rollback plans Submit change requests through JLL's formal change management process (CAB approvals, release windows, stakeholder notifications) Execute production deployments: coordinate cutover activities, migrate configurations, validate connectivity, and monitor initial data flows Conduct post-deployment

ongoing operations Day-to-Day Responsibilities Integration Delivery Own the design → build → UAT → deploy lifecycle for integrations between Aravo and PeopleSoft, Trustpair, Ingenious, Omnea, Yardi,

data discrepancies, diagnose API errors, coordinate with platform owners, and implement fixes Maintain integrations through platform updates and releases: ensure compatibility with monthly Aravo releases and related system changes Perform data reconciliation and validation to ensure integration accuracy and catch issues before they impact business processes Monitor integration health using logs, error reports, and dashboards Trustpair Platform Ownership Serve as operational owner for Trustpair: manage configuration changes, user access, and business stakeholder relationships Coordinate
