Systems Administrator - IV

Job Title: Senior Middleware Automation Engineer (CI/CD & IaC)

Role Overview
We are seeking an experienced Middleware Automation Engineer to modernize our application hosting and infrastructure delivery processes. This role is focused on moving away from manual configuration toward a fully automated, scalable "pipeline-first" model. You will be responsible for the end-to-end automation of the application server lifecycle-from server provisioning and configuration management to complex application deployments.
This is a technical, hands-on position. You will not only be maintaining middleware stability but also architecting the CI/CD frameworks that enable our teams to release software with speed and consistency. If you have deep experience in traditional middleware administration and a passion for automating away manual operational tasks, this role is for you.

Key Responsibilities
Automation & CI/CD Engineering
• Pipeline Development: Design, develop, and maintain high-performance CI/CD pipelines. Ensure end-to-end automation for build, deployment, validation, and release processes across development, staging, and production environments.
• Infrastructure as Code (IaC): Lead the transition to IaC principles using Terraform. Build and manage reusable infrastructure modules to ensure environment consistency.
• Configuration Management: Utilize Ansible to automate middleware administration. Develop robust playbooks for server provisioning, patch management, and automated configuration enforcement.
• Troubleshooting & Support: Act as the Tier-3 escalation point for pipeline failures, deployment bottlenecks, and automation-related anomalies in mission-critical production environments.

Middleware Governance & Security
• Platform Administration: Provide expert-level administration for enterprise application server environments. Ensure optimal performance, scalability, and stability.
• Security & Compliance: Implement "security-as-code" by automating SSL configurations, certificate management, and middleware security hardening protocols.
• Operational Excellence: Continuously identify and eliminate manual operational tasks, driving the "automation-first" mindset across the infrastructure team.

Qualifications & Requirements
Minimum Qualifications
• Experience Baseline: Extensive hands-on experience in Middleware/Application Server Administration (e.g., WebSphere, JBoss, WebLogic, or Tomcat).
• Automation Mastery (Strict):
oAnsible: Expert-level experience in playbook development, configuration management, and middleware deployment automation.
oCI/CD: Strong experience building pipelines in Jenkins, GitLab CI/CD, or similar platforms.
• IaC Proficiency: Strong working knowledge of Terraform for infrastructure orchestration.
• Problem Solving: Proven ability to troubleshoot complex pipeline and deployment failures in large-scale enterprise environments.

Preferred Attributes
• Experience integrating monitoring and logging solutions into deployment pipelines.
• Deep understanding of middleware security configurations (TLS/SSL, keystores, security realms).
• Ability to work in an Agile environment and collaborate closely with cross-functional development teams.
