Commission Devops Administrator Jobs (NOW HIRING)

Platform DevOps Administrator

Position Summary

The Platform DevOps Administrator is a security-focused infrastructure professional responsible for securing, automating, maintaining, and supporting enterprise Linux and COTS application environments.

This role emphasizes security compliance, vulnerability remediation, platform automation, patching, middleware administration, and production operations. A primary measure of success is the ability to convert recurring operational and security tasks into controlled, repeatable Ansible automation while maintaining the stability and availability of 24×7 production systems.

The ideal candidate has strong Linux administration skills and experience with STIG compliance, CVE/KEV remediation, PKI, SSL/TLS certificates, Apache, JBoss, RabbitMQ, Node.js, and enterprise COTS platforms. The individual must be capable of independently troubleshooting and resolving technical and security issues with minimal supervision.

Linux Administration

• Install, configure, secure, patch, upgrade, and troubleshoot Red Hat Enterprise Linux (RHEL) environments.
• Support RHEL 6, 7, 8, and 9.
• Administer users, permissions, services, file systems, scheduled jobs, and system configurations.
• Troubleshoot operating system, networking, performance, storage, and application issues.
• Support backup, recovery, and disaster recovery activities.
• Monitor platform health, availability, performance, and security.

Middleware, Web Server & COTS Administration

• Administer Apache HTTP Server, JBoss, RabbitMQ, Node.js, and COTS application environments.
• Apply patches, upgrades, security updates, and configuration changes.
• Analyze vendor security advisories and determine applicability.
• Troubleshoot integrations between applications, middleware, Linux systems, and supporting infrastructure.
• Maintain SSL/TLS configurations for supported services.

Virtualization & Containers

• Support Linux workloads running in virtualized and containerized environments.
• Understand resource allocation, networking, storage, availability, and security considerations for virtual machines and containers.
• Assist in troubleshooting virtualization- and container-related platform issues.

Production Operations & ITIL

• Support 24×7 production environments.
• Respond to incidents, alerts, service requests, and operational issues.
• Follow ITIL practices for Incident, Problem, Change, Configuration, and Service Request Management.
• Document incidents, resolutions, and corrective actions.
• Adhere to established change management processes.
• Coordinate effectively with infrastructure, cybersecurity, application, network, database, and customer teams.

Independent Operations

• Analyze and resolve security and operational issues with minimal supervision.
• Research unfamiliar technologies and technical problems.
• Prioritize work based on risk and business impact.
• Own incidents through resolution and escalate when appropriate.
• Communicate technical issues and risks to both technical and non-technical stakeholders.
• Recommend automation and process improvements.

Required Qualifications
