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.\nABOUT ROLLING ARRAYS\nRolling 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).\nPOSITION SUMMARY\nRAC 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.\nWHAT YOU WILL DO\nOwn 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\nLead 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\nProduce 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\nDrive 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\nReview 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\nOwn integration UAT - designing the test plan, coordinating third-party test environment availability, and driving defect resolution to formal sign-off\nWHY ROLLING ARRAYS\nRAC'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.\nOUR CULTURE CODE\nSix values define how we operate every day at Rolling Arrays:\nThinking Smart - spot patterns, chase smarter solutions, and illuminate the path to greater productivity\nNever Stop Learning - refine and elevate skills constantly;

at Senior Interface Designer level this is an expected credential, not aspirational\nOracle Global Human Resources Cloud Implementation Professional - Senior interface leads who hold the Core HR module certification can independently validate data availability against the Oracle HCM object model without escalating to the functional team\nOracle Fusion Cloud Applications HCM Process Essentials certified - the foundational HCM credential confirming cross-module process understanding\nExperience designing interfaces between Oracle HCM and Oracle ERP, or between Oracle HCM and third-party payroll, HRIS, or access management systems in APAC\nBUSINESS & CONSULTING SKILLS\nIT architecture credibility - presents integration design decisions to client IT architects and holds the conversation at a technical authority level\nThird-party system management - manages external system teams who are not under RAC's control and escalates effectively when they are blocking the programme\nIntegration risk communication - translates interface catalogue status, risk, and readiness into a format that project leadership can make decisions from\nIDD governance - implements a sign-off process that prevents downstream defects without creating bureaucratic delays\nWorkstream leadership - owns the integration track end-to-end without requiring functional or technical hand-holding\nDeveloper quality review - reviews OIC builds against specifications, raises formal defects, and manages rework to resolution\nCAREER PROGRESSION\nSenior Consultant → Lead Consultant → Solution Architect → Practice Lead","description_format":"text","description_chars":6189,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Enterprise Apps Implementation Partners","HR & Payroll Software"],"lifecycle":[{"event":"open","at":"2026-10-14T11:53:08Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":0,"expected_fill_days":120,"reasons":["conf:3","velocity","win:early"],"computed_at":"2026-10-15T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/rolling-arrays-interface-designer-senior-consultant","json_url":"https://alion.io/job/rolling-arrays-interface-designer-senior-consultant.json","meta":{"generated_at":"2026-10-15T20:29:51Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":31226,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":685469},"rest":"https://alion.io/mcp/rest/get_company?id=685469"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frolling-arrays-interface-designer-senior-consultant"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Frolling-arrays-interface-designer-senior-consultant"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Frolling-arrays-interface-designer-senior-consultant"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/rolling-arrays-interface-designer-senior-consultant\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frolling-arrays-interface-designer-senior-consultant"}]}
