## About the Role

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.

Work Authorization:

Applicants must have valid, independent authorization to work in the United States. This position does not offer, support, or accept any form of sponsorship-whether employer, third-party, future, contingent, transfer, or otherwise. Candidates must be able to work for any employer in the U.S. without current or future sponsorship of any kind. Work authorization will be verified, and misrepresentation will result in immediate removal from consideration.

## Description

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
