Linux Support Engineer (VoIP)

We’re looking for a hands-on Linux Network Support Engineer to support mission-critical, real-time production platforms used by enterprise and regulated customers. This role is ideal for someone who enjoys deep troubleshooting, working close to the OS and network layer, and diagnosing issues in live environments.

This is not a traditional NOC or call-center role - and it’s not a pure VoIP or routing/switching position. The focus is on Linux systems, networking fundamentals, and analytical problem-solving, with SIP/voice technologies as part of the application layer.

What You’ll Be Doing

● Troubleshoot live production issues across Linux OS, applications, and networking

● Investigate problems directly from the Linux command line (services, logs, ports, routes)

● Analyze logs, traces, and packet captures to identify root cause

● Apply fixes, patches, and upgrades during planned maintenance windows

● Write clear MOPs (Methods of Procedure) for production changes

● Work closely with customer engineering teams and internal development teams

● Reproduce issues and provide actionable findings to engineering

● Participate in an on-call rotation supporting high-availability systems

What We’re Looking For (Core Requirements)

Must-Have

● Strong Linux troubleshooting experience (Red Hat, CentOS, Ubuntu, etc.)

● Comfortable working CLI-first (services, processes, logs, networking)

● Solid networking fundamentals (TCP/IP, ports, routing, firewalls)

● SIP / VoIP exposure (understanding call flows, signaling, RTP)

● Experience supporting production systems under real-world pressure

● Ability to analyze packet captures (Wireshark/tcpdump) and logs

● Clear communication skills when working with customers and engineers

Nice-to-Have

● Linux scripting (bash, shell)

● VMware or virtualized environments

● Familiarity with structured change management and maintenance windows

● Exposure to telecom or real-time communication platforms

What This Role Is (and Is Not)

This role IS:

● Linux-first

● Troubleshooting-heavy

● Hands-on and analytical

● Focused on production reliability

This role is NOT:

● A call-center or helpdesk position

● A pure VoIP/telephony role

● A routing/switching network design role

● A GUI-only support job

Why This Role Is Interesting

● Work on real systems that matter (high availability, regulated environments)

● Solve complex problems across OS, network, and application layers

● Hybrid schedule with strong work-life balance

● Competitive compensation and strong benefits

● Opportunity to grow deeper technically, not just manage tickets

If you enjoy diagnosing problems from the command line, understanding how systems

behave under load, and working close to Linux and networking – this role will be a strong

fit
