Linux Telecom Systems Engineer

If you’re the Linux professional everyone turns to when systems break - and you happen to have strong VoIP/SIP experience - this could be a great opportunity.

I’m partnered with a technically elite organization looking for a strong Linux Systems Administrator or Engineer to support complex, production Linux environments that power telecom and real-time voice infrastructure.

You don’t need to come from a traditional telecom engineering background. If you’re an excellent Linux professional who has worked with VoIP, SIP, networking, and production systems, we’d absolutely like to talk.

This is a hands-on role for someone who enjoys troubleshooting difficult technical problems, working from the command line, digging through logs and packet captures, and seeing issues through to resolution.

What You’ll Own:

• Deep troubleshooting across production Linux environments, primarily Red Hat
• Diagnose and resolve VoIP and SIP issues in live production environments
• Analyze logs and troubleshoot system, application, and infrastructure issues
• Perform packet-level analysis using Wireshark
• Investigate networking and connectivity issues across Linux-based systems
• Write MOPs for production changes, upgrades, and maintenance
• Support maintenance windows, patching, upgrades, and infrastructure updates
• Work directly with engineering and development teams to troubleshoot and resolve complex issues
• Participate in a rotating on-call schedule

• 5+ years of strong Linux systems administration or engineering experience
• Recent, hands-on experience supporting Linux in production environments
• Experience with VoIP and SIP - strong SIP troubleshooting is highly preferred
• Solid networking fundamentals including TCP/IP, DNS, SSH, routing, and related protocols
• Ability to analyze packet captures and network traces using Wireshark
• Strong command-line troubleshooting and log analysis skills
• Experience supporting high-availability or 24/7 environments
• Strong communication skills and the ability to work effectively with engineering teams

Bonus Points For:

• Bash, Python, Ansible, or other Linux automation/scripting
• VMware vSphere
• Basic Cisco IOS knowledge
• Diameter protocol
• Asterisk, IMS, SBCs, or other telecom/voice infrastructure
• Experience supporting telecom-grade or carrier-class environments
