You will play a key role in assessing current middleware platforms, migrating applications and configurations from source environments to target environments, and ensuring applications are fully operational after migration to an OpenStack-based infrastructure.</p><p>&#xa0;</p><p>&#xa0;</p><p>&#xa0;</p><p>What You’ll Do</p><p>&#xa0;</p><p>Lead Middleware Migration Activities: Support the migration of Java-based enterprise applications from one data center to another, ensuring application servers, configurations, dependencies, and runtime environments are properly

JVM settings, clusters, nodes, profiles, data sources, security settings, and related middleware components.</p><p>Support Java Application Platforms: Work closely with application teams to understand Java application architecture, runtime requirements, dependencies, and integration points to ensure successful migration and post-migration stability.</p><p>Perform Current-State Assessment: Analyze existing application and middleware architecture, document source environment configurations, and identify requirements for replatforming applications into the target OpenStack-based environment.</p><p>Migrate Middleware Configurations: Translate and migrate configurations from current source environments to target environments, ensuring consistency across application server settings, connection pools, JVM parameters, certificates, security configurations, and environment-specific variables.</p><p>Tune Performance and Stability: Perform application server performance tuning, JVM tuning, monitoring, troubleshooting, and capacity-related analysis to ensure applications run reliably before, during, and after migration.</p><p>Validate Application Availability: Conduct smoke testing, health checks, log reviews, and post-cutover validation to confirm that applications are up and running successfully in the target environment.</p><p>Coordinate Across Teams: Collaborate with multiple application, infrastructure, database, security, network, and project teams to plan migrations, resolve issues, and communicate technical status clearly.</p><p>Support Production Cutovers: Provide hands-on support during production migration windows, including after-hours and weekend work as required for application cutovers, validation, troubleshooting, and rollback support.</p><p>Troubleshoot Complex Issues: Act as an escalation point for middleware-related incidents, including deployment failures, application startup issues, connectivity problems, JVM errors, performance degradation, and configuration mismatches.</p><p>What You Bring (Requirements)</p><p>&#xa0;</p><p>Professional Experience: 10+ years of enterprise middleware administration experience supporting large-scale Java application environments, with strong exposure to data center migration or application replatforming initiatives.</p><p>IBM WebSphere Expertise: Deep hands-on experience installing, configuring, administering, troubleshooting, and tuning IBM WebSphere Application Server in enterprise environments.</p><p>JBoss Expertise: Strong experience supporting JBoss application server environments, including deployments, configuration management, performance tuning, and troubleshooting.</p><p>Java Application Knowledge: Solid understanding of Java application runtime behavior, JVM configuration, application deployments, logs, connection pools, certificates, and integration dependencies.</p><p>Migration Experience: Proven experience migrating applications and middleware platforms between data centers, including current-state discovery, configuration capture, migration planning, cutover execution, and post-migration validation.</p><p>Architecture Understanding: Ability to understand current application architecture and support replatforming efforts into an OpenStack-based target environment.</p><p>Configuration Management: Experience migrating middleware configurations from source environments to target platforms while ensuring application compatibility, security, and operational stability.</p><p>Performance Tuning: Strong knowledge of JVM tuning, thread pools, heap sizing, garbage collection, connection pool tuning, application server monitoring, and log-based troubleshooting.</p><p>Collaboration and Communication: Ability to work effectively with multiple application teams, infrastructure teams, and stakeholders while providing clear technical updates during complex migration activities.</p><p>Flexibility: Willingness to support production cutovers during evenings, nights, and weekends as required.</p><p>&#xa0;</p><p>&#xa0;</p><p>Bonus Points (Nice-to-Haves)</p><p>&#xa0;</p><p>Additional Middleware Platforms: Experience with Oracle WebLogic, Apache Tomcat, and Microsoft IIS.</p><p>Cloud and Virtualization Exposure: Experience supporting applications in private cloud or OpenStack-based
