The right candidate is a strongPeopleSoft integration developer who can independently take an interface from designthrough go-live — covering both batch and real-time patterns, delta (incremental) andfull data-refresh processing, secure file transport with encryption/decryption, andmodern REST API / OAuth2 integration — while protecting the integrity of deliveredPeopleSoft objects.Data flow context (no PHI in scope):GPO / contract & item data → enrichment SaaS platform → PeopleSoft FSCM ItemMaster / Inventory → HL7 integration engine (Infor Cloverleaf) → Epic Item File /OpTime.Key Responsibilities Design, develop, unit-test, and deploy multiple inbound and outbound interfaces between PeopleSoft FSCM and external systems (SaaS data- enrichment platform, clinical/HL7 systems, file-based partners). Build interfaces using both batch (scheduled) and real-time / near-real-time integration patterns, selecting the appropriate approach per use case. Implement delta / incremental processing (change-data capture, run-control watermarking, net-change logic) as well as full data-refresh loads, with restart ability and reconciliation. Develop secure file movement over SFTP / FTP, including PGP/GPG encryption and decryption of inbound and outbound files. Build and consume REST APIs following REST standards (proper HTTP verbs, status codes, resource modeling, pagination) and OAuth 2.0 authentication/authorization flows. Parse, generate, and transform XML and JSON payloads between PeopleSoft and external endpoints. Implement rowset-based processing in PeopleCode and Application Engine for efficient, set-based data handling. Design and create custom staging, configuration, and crosswalk tables to support interfaces without modifying or impacting delivered PeopleSoft tables, records, or structures; build and maintain key mapping / crosswalk logic between PeopleSoft keys and external system identifiers. Develop Fluid UI pages/components where configuration, monitoring, or exception-handling screens are required. Build robust error handling, logging, audit trails, and reconciliation reporting for every interface. Produce technical design documents, interface specifications, and runbooks; support SIT, UAT, go-live, and hyper care. Coordinate with functional analysts, the integration/HL7 team, the vendor, and InfoSec on secure-transport endpoints and data-handling requirements.Required PeopleSoft Technical Skills Application Designer — expert-level: records, pages, components, menus, Application Engine, File Layout, Component Interface, Application Packages, and PeopleCode. Integration Broker — service operations, message definitions, handlers, routings, queues; synchronous and asynchronous messaging; REST and SOAP service operations. Application Engine batch programs with rowset-based / set-basedprocessing, run controls, restart logic, and Process Scheduler. File Layout definitions for fixed-width, delimited (CSV), and XML file structures. REST API development and consumption following REST standards; OAuth 2.0 token-based authentication. XML and JSON generation, parsing, and transformation. SFTP / FTP secure file transport; encryption and decryption of files (PGP/GPG) and management of keys/certificates. Fluid UI development (Fluid pages, components, and navigation). Designing custom tables and objects without impacting delivered structures, and building key-mapping / crosswalk tables and logic. SQL (Oracle), PS Query; SQR and nVision exposure a plus.Supply Chain / Functional Knowledge Hands-on experience with PeopleSoft FSCM Inventory and Purchasing / eProcurement modules. Item Master management — Item Loader, item setup, units of measure, item categories, manufacturer/vendor item cross-references, par/replenishment data. Understanding of inventory management and supply chain processes: requisition-to-PO, receiving, replenishment, item lifecycle. Healthcare supply chain experience strongly preferred — familiarity with GHX, GPO/Premier contracting, and item identifiers (GTIN, UDI, HCPCS) is a significant plus.Integration Pattern Expertise Clear command of batch vs. real-time trade-offs and when to apply each. Delta / incremental processing vs. full data refresh — design, performance, and reconciliation considerations for high-volume item and contract data. Interface error handling, exception management, audit logging, restartability, and reconciliation. Performance tuning of high-volume interfaces (millions of rows per cycle).Required Qualifications 8+ years of hands-on PeopleSoft technical development experience, with a strong concentration in interfaces and integrations. Demonstrated record of independently delivering multiple PeopleSoft interfaces end-to-end (design → build → test → deploy → support). Experience on PeopleSoft FSCM / Supply Chain (Inventory, Purchasing, Item Master). Strong People Code, Application Engine, Integration Broker, and File Layout skills. Experience with secure integrations: REST APIs, OAuth2, SFTP, and file encryption/decryption. Excellent written and verbal communication; able to produce clear technical specs and work directly with functional teams, vendors, and security.Preferred / Nice-to-Have Healthcare / hospital ERP delivery experience. Exposure to Epic (Item File / OpTime / SUP interface), HL7 v2, and integration engines such as Infor Cloverleaf. Experience integrating PeopleSoft with third-party SaaS / cloud platforms. Familiarity with MOVEit / managed file transfer, MuleSoft/iPaaS, or API gateways. PeopleTools 8.6x experience; AIX/Linux environment familiarity.Environment PeopleSoft FSCM & HCM 9.2 (on-premise), PeopleTools 8.62, Oracle Exadata database tier. Integration landscape includes Integration Broker, Infor Cloverleaf (HL7),GHX, Epic, MOVEit, SFTP, and external SaaS endpoints.
