📍 Job Overview

Job Title: Oracle Interface Designer - Consultant

Company: Rolling Arrays - Consulting

Location: Mumbai, Maharashtra, India

Job Type: Full-Time

Category: Revenue Operations / Sales Operations / GTM Operations (Focus on System Integrations & Data Flow)

Date Posted: May 18, 2026

Experience Level: 2-5 years (Consultant level, with potential for growth)

Remote Status: Hybrid (with potential for remote work based on performance and project needs)

🚀 Role Summary

• Design and document precise integration specifications between Oracle HCM and third-party systems, acting as a critical functional bridge for technical teams.

• Elicit and meticulously capture detailed integration requirements, focusing on data triggers, frequency, error handling, and business impact.

• Validate the accuracy and completeness of built integrations against design specifications, ensuring adherence to functional requirements and raising defects when necessary.

• Develop and execute comprehensive integration test cases, encompassing positive, negative, and volume scenarios to ensure robust data flow and system performance.

• Maintain a live, accurate interface inventory, serving as a central repository for all integration details throughout client engagements.

📝 Enhancement Note: This role is positioned as a "Functional Interface Designer," emphasizing the critical need for detailed, developer-ready specifications. The core value lies in producing Interface Design Documents (IDDs) so precise that developers can execute them with minimal clarification, thereby directly impacting project efficiency and defect reduction. This aligns with the broader GTM Operations goal of enabling seamless data flow for critical business processes.

📈 Primary Responsibilities

• Lead and facilitate integration requirements workshops with client HR and IT stakeholders, delving into trigger mechanisms, frequency, error ownership, rejection handling protocols, and the business consequences of integration failures.

• Produce comprehensive and unambiguous Interface Design Documents (IDDs) for all in-scope integrations, detailing source/target systems, trigger events, data direction, frequency, field-level mapping with transformation rules, code conversions, error handling strategies, volume estimates, and reconciliation methods.

• Accurately map Oracle HCM data objects to target system fields, understanding the capabilities of REST API, HCM Extract, and SOAP services, and proactively identifying mapping gaps where Oracle may not hold the required attributes.

• Collaborate closely with Oracle Integration Cloud (OIC) or other middleware developers to validate built integrations against IDD specifications, meticulously raising formal defects with clear evidence and documenting any approved deviations.

• Develop, execute, and manage comprehensive integration test cases, including positive, negative, and volume scenarios, and actively drive defect resolution to successful closure.

• Maintain a disciplined approach to managing the interface inventory as a dynamic and live document throughout the project lifecycle, ensuring accuracy and accessibility for all stakeholders.

📝 Enhancement Note: The responsibilities heavily emphasize the "Interface Design Document" (IDD) as the central deliverable. This goes beyond simple data mapping to encompass the entire lifecycle of an integration, including requirement elicitation, technical validation, and testing. This requires a deep understanding of both functional HR processes and the technical nuances of data integration, a common requirement in advanced Revenue and Sales Operations roles focused on system interconnectivity.
