Description

You can take an Interface Design Document, build the OIC integration end-to-end, handle the error cases the document did not cover, deploy it across environments, and hand over technical documentation that the support team can use a year later. That is the standard we build to. ABOUT ROLLING ARRAYS Rolling Arrays is a private equity-backed, award-winning HR Tech consulting firm — Asia Pacific's premium partner for enterprise HR digital transformation. Headquartered in Singapore and with offices across India, Malaysia, Australia, and Hong Kong, we have delivered more than 200 HR Transformation projects since our founding in 2009, and were recognised as one of Singapore's Top 100 fastest-growing companies in 2025. We specialise in SAP SuccessFactors, Oracle HCM, and Workday across the full delivery spectrum: HR process design and consulting (ALIGN), technology implementation (AUTOMATE), change management and adoption (ADOPT), and managed support services (AMS). POSITION SUMMARY RAC is hiring an Interface Developer to build Oracle HCM integrations using Oracle Integration Cloud (OIC). You will develop, test, and deploy integration flows between Oracle HCM Cloud and third-party systems, working from functional Interface Design Documents and translating them into production-grade OIC implementations. WHAT YOU WILL DO Build Oracle Integration Cloud flows from functional Interface Design Documents — implementing trigger, adapter connections, orchestration logic, data transformation, and error handling without requiring functional re-explanation of the business requirement Configure OIC adapters across the full HCM integration surface — Oracle HCM Cloud adapter for REST API calls, HDL-based operations, and Atom Feed subscriptions; REST and SOAP adapters for third-party systems; FTP adapter for SFTP file transfer; and database adapter for ATP persistence patterns Build XSLT data transformations — field mapping, conditional logic, array iteration for multi-record payloads, data type conversions, and null value handling Configure fault handling — scope-level fault handlers, global error handlers, retry policies, and alert notifications for failures that require human intervention Deploy integrations across environments — configuring environment-specific connection parameters, promoting via OIC Projects, deploying to Test/UAT/Prod, and validating post-deployment in each environment Perform unit testing and contribute to SIT — building test scenarios for happy path, error conditions, and edge cases, documenting results, and resolving defects to sign-off WHY ROLLING ARRAYS Every integration RAC builds goes to a live client environment with a real go-live dependency. You will develop OIC depth across the full Oracle HCM module integration surface in APAC legislative contexts, with a clear pathway to Senior Interface Developer and Integration Architecture roles.
