You will be the first line of technical response — monitoring application health, picking up incidents and service requests, running documented diagnostics, fixing straightforward defects, and escalating with clear evidence when an issue needs deeper analysis. This is a strong learning role: you will build real production troubleshooting skill on Java and Spring Boot systems, working alongside senior engineers who will guide and review your work. </p><p><br /></p><p>Key Responsibilities </p><p><br /></p><p>Incident & Service Request Handling </p><p><br /></p><p>Act as first-line technical response for assigned Java applications — acknowledge, triage and resolve incidents and service requests within agreed SLAs. </p><p><br /></p><p>Execute documented runbook and SOP procedures accurately for known issues and standard requests. </p><p><br /></p><p>Perform initial diagnostics — check application logs, service and JVM status, job status, connectivity, disk and memory — before escalating. </p><p><br /></p><p>Escalate unresolved or high-impact issues to the Senior Software Engineer or Lead with a clear summary of symptoms, checks performed and findings. </p><p><br /></p><p>Keep tickets accurately updated at every stage and communicate status to users in plain, professional language. </p><p><br /></p><p>Handle user access requests, data extraction requests and standard configuration requests per approved processes. </p><p><br /></p><p>Monitoring & Proactive Operations </p><p><br /></p><p>Monitor dashboards, alerts, batch schedules, queues and integration flows throughout the shift. </p><p><br /></p><p>Respond to alerts proactively and take documented corrective action before users are impacted. </p><p><br /></p><p>Run daily, weekly and month-end health checks and publish results to the team. </p><p><br /></p><p>Track batch job failures, reruns and interface reconciliation, escalating exceptions promptly. </p><p><br /></p><p>Perform routine housekeeping — log rotation and clean-up, archival, space checks and scheduled restarts. </p><p><br /></p><p>Debugging & Defect Support </p><p><br /></p><p>Read and interpret Java stack traces and application logs to identify the failing component. </p><p><br /></p><p>Write SQL queries to investigate data-related issues and validate application behaviour. </p><p><br /></p><p>Reproduce reported defects in test environments and document the reproduction steps clearly. </p><p><br /></p><p>Fix simple, well-scoped defects in Java/Spring Boot code under supervision, with unit tests and peer review. </p><p><br /></p><p>Assist senior engineers during deeper investigations by capturing thread dumps, heap dumps and diagnostic evidence. </p><p><br /></p><p>Release & Change Support </p><p><br /></p><p>Support deployments and release windows — execute assigned checklist steps and post-implementation validation. </p><p><br /></p><p>Perform smoke testing and health verification after releases and report issues promptly. </p><p><br /></p><p>Follow the change process for every production action, without exception. </p><p><br /></p><p>Documentation & Learning </p><p><br /></p><p>Create and update knowledge base articles for issues you resolve so they become repeatable. </p><p><br /></p><p>Keep runbooks and SOPs current, flagging steps that are outdated or unclear. </p><p><br /></p><p>Complete structured shift handovers so no issue is lost between shifts. </p><p><br /></p><p>Build depth in Java, Spring Boot and the business domain through structured learning, pairing and mentoring. </p><p><br /></p><p>Technical Skills </p><p><br /></p><p>Java Fundamentals </p><p><br /></p><p>Core Java (8/11/17) — OOP, collections, exception handling and the ability to read and understand existing code. </p><p><br /></p><p>Spring Boot basics — application structure, configuration files, REST controllers, dependency injection. </p><p><br /></p><p>Ability to read and interpret Java stack traces and application logs. </p><p><br /></p><p>Basic understanding of Hibernate/JPA and how application code reaches the database. </p><p><br /></p><p>Awareness of JVM concepts — heap, garbage collection, threads — and the tools used to inspect them. </p><p><br /></p><p>JUnit basics for validating fixes. </p><p><br /></p><p>Platform, Data & Tooling </p><p><br /></p><p>SQL — queries with joins, filters and aggregation for data investigation. </p><p><br /></p><p>Databases: Oracle, PostgreSQL, MySQL or SQL Server. </p><p><br /></p><p>Linux/Unix command line — navigating directories, grep/tail on logs, checking processes, disk and services. </p><p><br /></p><p>Application servers: awareness of Tomcat, JBoss or WebLogic and how to start, stop and check them. </p><p><br /></p><p>Version control with Git;
