Network Support Engineer (Telecommunications)

We’re looking for a Telecom/ VoIP Engineer who thrives in the deep end-someone who lives in Linux, understands VoIP/SIP at the packet level, and enjoys chasing down issues others can’t figure out.

You’ll be working on real telecom infrastructure supporting large-scale platforms used by major customers. If you get a rush from Wireshark analysis, SIP debugging, and CLI-based troubleshooting, you’ll feel right at home here.

What You’ll Be Doing

• Troubleshoot complex issues across Linux-based VoIP platforms
• Analyze SIP signaling, RTP flows, and network behavior
• Dive into packet captures (Wireshark/tcpdump) to find root causes
• Apply fixes, patches, and updates in live production environments
• Collaborate with engineering and customer teams on high-impact issues
• Write MOPs (Methods of Procedure) for production changes
• Gather logs and technical data to support escalations to development
• Support maintenance windows and platform upgrades

Do you have experience in Wireshark?, * 5+ years working in Linux environments (RHEL/CentOS/Ubuntu)

• Hands-on experience with VoIP technologies
• Strong working knowledge of SIP
• Proven ability to analyze packet captures (Wireshark)
• Solid networking fundamentals (TCP/IP, DNS, routing)
• Comfort working in the Linux command line

Bonus Points

• Experience with Asterisk, FreeSWITCH, Kamailio, or SBCs
• Scripting (Bash, Python, etc.)
• Exposure to Diameter protocol
• VMware or virtualized environments
• Cisco networking basics

Bottom Line

If you’re the person others go to when SIP calls fail, packets don’t make sense, and Linux logs tell a story, this is where you level up.
