Senior Administrator, Corporate Systems

Job Description

The Oracle Revenue Management and Billing (ORMB) Corporate Systems Senior Developer will be responsible for the end-to-end administration, deployment, and development of the ORMB application built on the Oracle Utilities Application Framework (OUAF). This role combines hands-on system administration — including fresh installations, environment provisioning, patch management, and release deployments — with Java-based development of enhancements, integrations, and batch processing solutions.

Working under the direction of the Technical Manager, this role requires frequent collaboration with functional business analysts, infrastructure/DBA teams, third-party vendors, and end users to ensure high availability, compliance, and continuous delivery of a quality finance/corporate systems application. The ideal candidate brings both deep administrative experience with ORMB/OUAF environments and strong Java development skills in large-volume financial systems.

Responsibilities

• System Administration & Environment Management

• Plan, execute, and document fresh installations of ORMB/OUAF across Development, QA, UAT, and Production environments on Linux/Unix servers

• Configure WebLogic application server, Oracle database connections, batch frameworks, and OUAF environment properties (ENVIRON.INI, SPLEBASE).

• Manage multi-environment topology including environment cloning, refresh, and rollback procedures.

• Apply Oracle-released CPU patches, SPU patches, and product fix packs to ORMB/OUAF environments following change management procedures.

• Coordinate patch testing in lower environments before promoting to Production; maintain patch inventory and compliance registers.

• Use Oracle OPatch / OUAF patch utilities (e.g., FW patch scripts) and validate post-patch environment integrity.

• Execute and oversee application deployments and release promotions across all environments using OUAF deployment utilities.

• Manage Configuration Migration (CM) packages, migration plans, and controlled rollouts via the OUAF Migration Assistant.

• Coordinate with DBAs for schema scripts, data migrations, and post-deployment validation.

• Monitor application health, JVM performance, batch throughput, and WebLogic thread pools; tune configurations to meet SLA targets.

• Maintain and update installation guides, runbooks, patch procedures, and environment-specific configuration documentation.

• Development & Enhancements

• Design and develop custom ORMB components — algorithms, service scripts, BPA scripts, business objects, business services, and portal zones — using Java and the OUAF framework.

• Build and maintain third-party integrations (e.g., tax engines, payment gateways, e-invoicing, ticketing systems) using REST/SOAP APIs and batch file-based patterns.

• Develop and optimize batch programs for high-volume billing and financial transaction processing, including performance profiling and JVM-level tuning.

• Collaborate with functional analysts and business stakeholders to gather requirements, propose solutions, and deliver enhancements aligned with business capabilities.

• Production Support & Operations

• Provide Tier 2/3 production support for ORMB including incident triage, root cause analysis, and resolution of batch failures, data anomalies, and integration errors.

• Run and schedule production batch jobs; maintain and modify interfaces, reports (BI Publisher), and scheduled tasks.

• Perform year-end processing support, system upgrades, and general technical modifications with minimal business disruption.

• Liaise with Oracle Support (SR management), infrastructure, and DBA teams to resolve platform-level issues.

• Collaboration & Governance

• Work with external vendors and internal teams to evaluate system changes; participate in design reviews, propose solutions, and document outcomes.

• Ensure all deployments and patches comply with change management, security, and audit policies.

• Support the ORMB V8 upgrade and other strategic migration initiatives, contributing to parallel-run testing and validation activities.

• Knowledge and Experience

• Bachelor's or Master's degree in Computer Science or Information Systems required.

• 4+ years of experience with Oracle ORMB or CC&B, including hands-on administration of OUAF-based environments (installations, patching, deployments).

• 4+ years of strong Java development skills with demonstrated ability to build and extend OUAF/ORMB framework components.

• Experience installing and patching ORMB/OUAF on Linux/Unix servers; familiarity with WebLogic administration and JVM tuning.

• Working knowledge of Oracle Database / SQL; ability to write and optimize queries against ORMB billing schema.

• Experience managing OUAF Configuration Migration (CM) packages and multi-environment promotion workflows.

• Ability to work independently and thrive in a high-profile environment while maintaining high attention to detail and quality.

• Strong communication skills to collaborate effectively with technical peers, business stakeholders, and third-party vendors.

• Preferred Knowledge and Experience

• Familiarity with Oracle patch delivery mechanisms (My Oracle Support, OPatch) and WebLogic patching procedures.

• Experience with CI/CD pipelines or scripted deployment automation for Java/OUAF applications.

• BI Publisher and/or Tableau experience is a plus.

• Financial industry experience with finance and/or accounting knowledge is beneficial.

• Experience with ORMB V8 (v8.x) and knowledge of differences from legacy CC&B / ORMB v2.x.
