Designs, develops, and optimizes Oracle database solutions and APIs for mission-critical applications. Responsibilities include writing SQL and PL/SQL, managing database objects and scheduled jobs, implementing Oracle Advanced Queue workflows, tuning performance, and supporting secure API design and lifecycle management. The role also covers authentication, routing, throttling, monitoring, documentation, version control, Agile collaboration, and coordination with technical teams on system integrations.
Summary Generated by Built In
We are seeking an experienced Database & API Developer to design, develop, and optimize data-driven and API-driven solutions supporting mission-critical business applications. The role includes analyzing existing systems—core data sources, billing modules, and API-based procedures—and extending PL/SQL logic built on the billing platform to deliver new functionality.
The developer will extract and analyze data from core systems, interpret high-level business requirements, and translate them into database extensions or API-related tasks, planning and tracking activities in Jira according to the delivery roadmap. The role also involves identifying and documenting database-side requirements for integrations with external and internal platforms (mobile applications, web portals, backend systems), designing and delivering the required APIs, and coordinating implementation with technical teams.
Additionally, the developer is expected to maintain thorough, clear, and up-to-date technical documentation, ensuring transparency, traceability, and efficient long-term maintenance. The ideal candidate demonstrates strong SQL/PL/SQL expertise, solid understanding of API design and lifecycle management, and the ability to work effectively in a fast-paced Agile environment.
