- 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
- Integrate extensions with Fusion SaaS using REST APIs, OIC services, FBDI/HDL, and BICC extracts where required.
- 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.
