• Leverage a solid understanding of distributed microservices architectures to isolate faults and trace data flows across decoupled systems.
• Trace application workflows and debug issues seamlessly across the Angular frontend, Java backend, and middleware integrations.
• Author, analyze, and tune complex SQL queries to investigate data anomalies and resolve performance bottlenecks within intricate database schemas.
• Evaluate multi-application failures swiftly, perform deep-dive Root Cause Analysis (RCA), and deploy workarounds or fixes to minimize downtime.
• Manage tasks effectively by shifting focus across diverse application portfolios and environments without compromising troubleshooting quality or speed.
• Partner closely with DevOps, Infrastructure, and Development teams to facilitate smooth deployments, streamline release management, and maintain transparent business communication.
• Identify, log, and escalate critical software defects discovered in UAT or production environments directly to engineering teams for remediation.
• Guide external teams and end-users through complex application integration challenges, delivering clear technical guidance and timely resolutions.

Must Haves:

• Professional proficiency in Angular, including comprehensive hands-on experience with components, services, and UI layout building using HTML and CSS.
• Robust, production-level knowledge of Core Java and the Spring Boot ecosystem, alongside strong operational familiarity with Microservices environments and distributed system designs.
• Proven analytical skills with a methodical approach to navigating logs, isolating bugs, and defining definitive Root Cause Analysis (RCA).
• Deep understanding of SQL databases that spans advanced query writing, schema design inspection, and query performance optimization.
• Hands-on experience navigating OpenShift or Kubernetes container environments, alongside strong familiarity with the overall software deployment lifecycle.
• Strong exposure to RESTful APIs, web service integration, and core network fundamentals including HTTP and HTTPS protocols.
• Everyday proficiency with API testing suites like Postman, database IDE tools, and log aggregation stacks such as the ELK platform or similar log management systems.
• Good understanding of modern authentication and authorization mechanisms like OAuth and SAML 2.0.
• Familiarity with at least one caching system such as Redis, Hazelcast, or DataGrid.
• Exposure to message brokers and event-driven architectures, specifically Apache Kafka.
• Clear, polite, and professional communication with business stakeholders to gather incident details and provide transparent status updates during production glitches.
• Ability to compile routine operational metrics and present timely performance reports and status updates directly to management.
• Ability to mentor junior team members, guiding them through standard operational playbooks and runbook execution.

Good To Have:

• Familiarity with core system design principles, enabling a conceptual understanding of application structures, data flows, and infrastructure dependencies.
• Ability to independently develop and execute small Proof of Concepts (POCs) for application enhancements or new features based on evolving business requirements.
