• Develop solutions supporting transaction enrichment, approvals, and self-service functionality.
• Configure business rules, validations, and approval logic within custom components.
• Ensure reusability and maintainability through component-based design and modular architecture.

Data & Integration Layer

• Configure secure connectivity (OAuth2, certificates, SFTP) and handle authentication through OCI Identity and Access Management (IAM).
• Support backend automation using PL/SQL, Oracle REST Data Services (ORDS), and Server-Side Logic (SSL).
• Collaborate with data migration and reporting teams to ensure data consistency and auditability across environments.

Governance, Security & Quality

• Ensure all extensions adhere to Oracle PaaS governance, naming, and deployment standards.
• Design solutions that align with Fusion Application Security (Roles, HCM Data Roles, Duty Roles) and data segregation principles.
• Conduct code reviews, peer validations, and maintain configuration control through Visual Builder Studio (VBS) and Git.
• Support SIT, UAT, and performance testing phases; troubleshoot and optimise custom components for scalability.
• Document technical designs, configuration guides, and release notes in line with project quality processes.

Innovation & Enablement

• Identify opportunities to leverage AI/automation, APEX plug-ins, or VBCS accelerators to improve user experience and delivery efficiency.
• Contribute to R&D and internal capability-building on low-code / no-code development within OCI.
• Mentor junior developers and guide offshore delivery teams in best practices for VBCS/APEX and Fusion extensions.

• Required Skills & Experience

• 8+ years of Oracle Cloud or PaaS development experience, including at least 3+ years in VBCS and/or APEX.
• Proven track record in delivering custom extensions for Oracle Fusion ERP and HCM Cloud.
• Strong expertise in VBCS application design, REST API consumption, event-driven flows, and security integration.
• Hands-on experience with Oracle APEX on ATP/ADW or DBCS, including backend logic using PL/SQL and ORDS.
• Proficiency with Fusion SaaS REST APIs, FBDI, HDL, and BICC for integration support.
• Good understanding of Fusion security model, OAuth2, and OCI IAM.
• Familiarity with Visual Builder Studio (VBS), Git, and CI/CD pipelines for extension deployment.
• Excellent analytical and documentation skills with strong attention to UI/UX detail.
• Ability to work effectively in multi-wave, public-sector transformation programmes with robust assurance controls.
