Job description

Job Description

Our Telecom Client is seeking a Systems Engineer III to support the lifecycle management of enterprise applications and systems within their internal lab environment. This role centers on systems administration and data analytics, with a secondary emphasis on application support. The ideal candidate is a well-rounded systems engineer who can administer Linux/Windows environments, analyze and reconcile data across systems, and support the applications the team manages. This is not a specialized subject-matter-expert position; rather, we are looking for a strong generalist with solid fundamentals who can learn our platforms and grow into ownership over time.

Key Responsibilities

• Perform day-to-day systems administration across Linux environments (patching, updates, configuration, monitoring, and maintenance)
• Perform updates and troubleshooting on the DNS to provide upkeep and support to the internal lab
• Support data accuracy and integrity efforts, including data analysis, reconciliation, cleanup, and reporting across managed platforms
• Provide application support for team-managed enterprise applications, including troubleshooting, access management, and coordination with vendors and other lab teams
• Assist with automation and scripting to streamline routine operational and reporting tasks
• Document procedures, runbooks, and configurations to maintain accurate operational records

This role is offering 45-48 an hour.

It is onsite 4 days a week in Greenwood Village near Parker, Colorado.

Skills and Requirements

• 3+ years of hands-on systems administration experience (Linux Specifically)
• Demonstrated experience with data analysis and reporting (e.g., manipulating, reconciling, and validating data across systems using tools such as SQL, Excel, or scripting)
• Proficiency with scripting/automation (e.g., Python, Bash, or PowerShell)
• Strong troubleshooting and problem-solving skills across systems and applications
• Solid understanding of core networking and infrastructure fundamentals
• Ability to document work clearly and follow structured operational processes
• Familiarity with security and access-control principles (e.g., RBAC)
• Working knowledge of how IPAM (IP Address Management) and DNS function at a fundamental level
• Fundamentals of application support engineering (application lifecycle, access provisioning, vendor coordination)
• Exposure to platforms such as NetBox, Infoblox, or PowerDNS (familiarity, not expertise, is sufficient)
• Experience with monitoring tools (e.g., Zabbix, Grafana) or ticketing/ITSM systems (e.g., Jira)
• Experience working in a lab, data center, or enterprise infrastructure environment
• Familiarity with version control (Git) and CI/CD concepts
• Experience with API-based data integration or automation between systems
