Description

Integration risk is invisible until go-live. The Senior Interface Designer is the person who makes it visible — knowing which interfaces are on the critical path, which third-party system teams are behind, and which mapping decisions will create a production defect six months after go-live. That awareness comes from owning the workstream, not contributing to it. 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 specialize 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 seeking a Senior Functional Interface Designer to lead the integration design workstream on Oracle HCM implementations. You will own the end-to-end interface catalogue — from requirements elicitation and IDD production through developer handoff, testing, and UAT sign-off — acting as the functional integration authority for the delivery team and the primary interface contact for the client's IT architecture team. WHAT YOU WILL DO Own the integration catalogue from day one — producing the full interface inventory within the first two weeks of design phase, classifying each interface by pattern, direction, criticality, and third-party owner, and maintaining it as the single source of truth throughout the project Lead integration requirements workshops — extracting trigger conditions, error handling expectations, SLA requirements, and business consequence of failure, and producing workshop outputs that flow directly into IDD authoring Produce and own all Interface Design Documents — at a level of precision that an OIC developer can build from without functional re-engagement, with a client IT sign-off process before development begins Drive interface prioritisation and phasing — recommending development sequence based on go-live criticality, third-party readiness, and data migration dependencies, and escalating when a third-party team is blocking sign-off Review and approve OIC developer builds against IDD specifications — logging formal defects with reference to specific IDD fields and distinguishing design deviations from legitimate technical implementation decisions Own integration UAT — designing the test plan, coordinating third-party test environment availability, and driving defect resolution to formal sign-off WHY ROLLING ARRAYS RAC's Oracle HCM programmes are multi-country, multi-integration engagements where integration risk is one of the top three programme risks on every project. As the functional integration lead, you own that risk — and you have the visibility, authority, and pathway to Solution Architect that comes with it.
