## About the Role

Do you have experience in Linux administration?, 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

If Linux is your native language and you can read a SIP trace like a novel, keep going…

You'll be in the middle of high-impact telecom infrastructure, the kind powering real-world, large-scale platforms. When things break, you're the one who figures out why.

What You'll Be Doing

 * Live in Linux-troubleshooting complex VoIP environments
 * Break down SIP signaling + RTP flows at the packet level
 * Dive into Wireshark/tcpdump to uncover what others miss
 * Solve production issues in real time (no training wheels)
 * Work alongside engineers who actually know their stuff

What You Bring

 * Strong Linux background (RHEL/CentOS/Ubuntu) - non-negotiable
 * Solid VoIP + SIP experience (telecom mindset matters)
 * Packet analysis skills (Wireshark, tcpdump)
 * Networking fundamentals (TCP/IP, DNS, routing)
 * Comfort in the CLI-no GUI safety nets

Bonus if you've touched Asterisk, FreeSWITCH, Kamailio, SBCs, or done any scripting

**U.S. Citizens or Green Card holders only

Why This Role Hits Different
You're not supporting users - you're supporting infrastructure that can't fail.
You're not guessing- you're proving root cause.
You're not coasting - you're getting sharper every day.
