Linux Infrastructure Engineer – VoIP Platforms

U.S. citizens or permanent residents only. No sponsorship available.

This role is for someone who doesn’t just “work with Linux” — you own it.

I’m working with a strong telecom-focused organization seeking a Linux Infrastructure Engineer with real-world VoIP platform experience and solid SIP expertise. If you’ve supported voice infrastructure in production and know how to trace a problem from the CLI all the way down to packet level — this is your lane.

We need someone technical. Confident. Battle-tested.

What You’ll Be Doing:

• Supporting and troubleshooting Linux-based VoIP platforms in live environments
• Diagnosing SIP signaling and call flow issues
• Performing deep log analysis from the Linux command line
• Reviewing and analyzing packet captures (Wireshark)
• Applying patches, updates, and infrastructure fixes
• Writing MOPs for production changes
• Participating in upgrades, maintenance windows, and system improvements
• Partnering with engineering teams to escalate and resolve complex issues

What You Must Have:

• 5+ years of Linux systems experience (Red Hat or similar)
• Recent, hands-on VoIP experience in production
• Strong SIP troubleshooting knowledge
• Solid networking fundamentals
• Comfort working directly in Linux CLI
• Ability to analyze packet captures and system logs
• Strong communication skills — you can explain what’s happening and why

Nice to Have

• Linux scripting
• VMware experience
• Basic Cisco IOS knowledge
• Exposure to telecom infrastructure environments

Why This Is a Strong Move:

You’ll be working on real voice platforms — not theoretical lab systems. This is a hands-on infrastructure role where Linux and VoIP expertise truly matter. The environment values technical depth and people who can think independently, not just follow playbooks.

If you’re a Linux infrastructure professional with serious VoIP and SIP experience and you’re ready for your next move in the Carteret area, let’s connect.
