The role requires strong expertise in ServerHardware, Server OS and schedulers, Oracle Database, Middleware(WebLogic, Forms & Reports, WebSphere), integration tools for maintaining server performance as per requirement and project delivery, along with proven leadership in managing stakeholders, migrations and regulatory-driven projects across APAC.

Key Responsibilities:
  • Lead end-to-end project delivery (requirement gathering, design & Architecting, capacity planning, scheduling, execution, testing, and go-live).
  • Analyse client needs to design & develop solutions using mathematical analysis for Server performance and capacity planning.
  • Lead end-to-end migration projects covering servers for database, middleware, scheduling tools, and OS platforms, ensuring smooth transition with zero business disruption.
  • Manage infrastructure migration projects (OS upgrades, DB migrations, Middleware upgrades, Autosys job transitions, MQ/SSO migrations).
  • Coordinate with stakeholders, vendors, and cross-functional teams across multiple countries to ensure timely project execution.
  • Oversee production L3 support for middleware & DB environments, ensuring compliance with regulatory standards (e.g., OCC).

• Installand configure Oracle Databases (9i-19c), including RAC and standaloneenvironments, with proper sizing, storage allocation, and security hardening.

• Performinstallation and configuration of Oracle WebLogic Server (12c/14c),including creating domains, clusters, and managed servers for high availabilitysetups.
