This is an on-site L3 support role based in India, serving client-facing operations and SLA-driven environments.

Role & Responsibilities

  • Serve as the L3 escalation point for production incidents in Java/Spring-based applications; lead incident remediation and ensure timely resolution within SLAs.
  • Diagnose and remediate complex issues across Java, Spring Boot, application servers (Tomcat/WebLogic/JBoss), middleware, and SQL back-ends; perform root-cause analysis and implement permanent fixes or workarounds.
  • Collaborate with development and QA teams to triage defects, deliver code fixes or hotfixes, validate patches in pre-prod, and coordinate safe deployments and rollbacks.
  • Monitor application health using APM and logging tools (Splunk/ELK/New Relic); create and tune alerts, dashboards, and automated diagnostics to reduce MTTD/MTTR.
  • Own change, release, and on-call responsibilities following ITIL best practices; document incidents, produce RCAs, and drive continual service improvements.
  • Create and maintain runbooks, knowledge articles, and automation scripts; mentor L1/L2 engineers to improve first-time fix rates and operational efficiency.

Skills & Qualifications
Must-Have

  • 4+ years hands-on experience in Java application support or production support with strong Java (8+) and Spring/Spring Boot troubleshooting skills.
  • Proven experience with application servers (Tomcat, WebLogic, JBoss), Linux administration, and SQL databases (Oracle/MySQL/Postgres).
  • Strong log & APM troubleshooting experience (Splunk, ELK/Kibana, New Relic) and ability to analyze heap/thread dumps and GC behavior.
  • Solid working knowledge of incident management, SLA-driven support, on-call rotations, and ITIL processes.
  • Familiarity with CI/CD pipelines (Jenkins), basic container/Docker usage, and scripting (Shell/Python) for automation.
  • Experience using Jira/Confluence for ticketing, knowledge management, and change/release coordination.

Preferred

  • Experience with microservices, RESTful APIs, and messaging systems (Kafka/RabbitMQ).
  • Exposure to cloud platforms (AWS/Azure) and orchestration (Kubernetes).
  • Background in banking, financial services, or fintech with domain knowledge of payments, settlements, or core banking apps.
  • Relevant certifications (Oracle Java, ITIL Foundation) or strong demonstrable troubleshooting portfolio.

Benefits & Culture Highlights

  • On-site role in India with competitive compensation, shift/onsite allowances, and comprehensive health benefits.
  • Growth-oriented culture: training allowance, certification support, and clear career path to Application Operations Lead or Engineering roles.
  • High-impact, collaborative environment focused on automation, reliability engineering, and continuous improvement.

Location: India (ON-SITE). If you are a detail-oriented Java troubleshooter who thrives under SLA pressure and enjoys turning operational pain points into permanent improvements, apply to join a high-performing support organization focused on reliability and customer success.
