• Develop and enhance interface-related Oracle objects (PL/SQL packages, procedures, triggers, views) and server scripts (Shell, Python, SQL*Loader)
• Perform impact analysis before changing production interfaces or data structures
• Contribute to data pipelines and workflow orchestration (e.g., Argo Workflows) for cross-system data flows
• Produce technical design documents, interface specifications and runbooks
Middleware Platform & WebLogic Operations
• Deploy, configure and maintain WebLogic domains and clusters in high-availability (HA) and
disaster-recovery (DR) configurations, ensuring installations meet standards and technical specifications
• Tune JVM, thread pools, JDBC data sources and JMS resources for high-throughput retail transactions
• Monitor middleware and application health using tools such as Dynatrace, Grafana, NMON or open-source equivalents, and act on alerts before they affect stores
• Support ORDS-based REST APIs, including connection-pool, authentication, availability and performance troubleshooting
• Work with Infrastructure on load balancing and edge components (F5, ALB/NLB, WAF, DNS) and on identity integration (OID/OAM, LDAP, PAM)

• Help design DR strategies and plan and execute failover tests to confirm RTO/RPO targets
Production Support (L2/L3)
• Trace and troubleshoot integration failures end to end across source applications, Oracle RIB/JMS/AQ, batch processes, APIs and Oracle Retail target tables; reconcile message status with actual business data
• Monitor and recover failed or stuck RIB messages, adapters, queues and batch jobs, using controlled retry, replay and restart procedures that prevent duplicate or missing transactions
• Investigate Oracle Retail batch dependencies and failures using Automic/UC4, application logs, restart tables, file processing status and database evidence
• Lead root-cause analysis (RCA) for critical incidents and put preventive measures in place
Delivery & Collaboration
• Participate in Retail system migration and modernization initiatives, including cloud re-platforming and database migration
• Work with QA on testing (SIT/UAT) and with DevOps on CI/CD pipelines and deployments
• Collaborate with Development, Operations, Infrastructure and Business teams across the application lifecycle
• Run knowledge-transfer sessions and provide technical clarification to the team and offshore partners

• Hands-on integration experience with Oracle RIB, SOA Suite, OSB, JMS/AQ or equivalent
• Solid understanding of integration patterns (pub/sub, file-based, REST/SOAP APIs) and data formats (XML, JSON, CSV)
• Strong Linux/Unix skills with Shell scripting; Python is a plus

• Experience designing or testing HA/DR setups against RTO/RPO targets
• Familiarity with cloud platforms (Tencent Cloud, OCI), containers/orchestration (Kubernetes, Argo) and automation tools (Ansible)
