Role Summary

The Middleware Engineer / Application Server Engineer is responsible for designing, building, configuring, deploying, and supporting middleware platforms that run business-critical applications. The primary technology stack includes JWS Tomcat, Red Hat JBoss EAP, and NGINX, with a focus on high availability, security, performance, and compliance across non-production and production environments. The role partners with application teams, platform engineering, cloud, security, and operations to deliver resilient and scalable middleware services.

Key Responsibilities

1) Middleware Platform Engineering

• Design and maintain standardized middleware configurations, including clustering, load balancing, and SSL/TLS.
• Manage middleware lifecycle activities: upgrades, patching, and decommissioning.
• Support both embedded and standalone middleware deployments.

2) Operations Production Support

• Provide L2/L3 production support for middleware platforms.
• Troubleshoot complex issues across performance, memory, threading, connection pooling, and JVM tuning.
• Perform root cause analysis (RCA) and implement permanent fixes.
• Support incident, problem, and change management processes (ITIL-aligned).

3) Deployment Automation

• Support application deployments (WAR/EAR/JAR) on Tomcat/JBoss, including container environments(preference noted for Amazon ECS).
• Work with CI/CD pipelines (example given: GitLab CI) for automated deployments.
• Implement and maintain automation using shell scripting and configuration/automation tooling such as Chef (or similar).

4) Security Compliance
