Job Summary

About the role: You will own and manage our telephony platform and the Linux systems. The cloud and DevOps piece is deliberate; our platform runs on cloud infrastructure, and we want the person maintaining it to eventually deploy and automate it themselves. One doesnt need Cloud DevOps experience coming in. We hire on telephony and Linux fundamentals; youll have the mentorship, the time, and the real ownership to build the rest here.

Responsibilities

Telephony - Build and maintain Asterisk and FreeSWITCH installation, upgrades, configuration, hardening
Write and debug dial plans: routing, IVR, queues, time conditions, failover
Root cause from SIP traces and RTP streams
Linux (equally core) - Own the servers: provisioning, patching, hardening, capacity, backups, recovery
Diagnose system-level performance problems
Manage the networking stack: routing, DNS, NTP, firewalls, and the packet path a call actually takes
Cloud DevOps (where the role grows): Cloud fundamentals, then automation in Bash or Python, then monitoring, containers, and CI/CD as you get comfortable

Requirements

Telephony - 2 to 3 years hands-on with Asterisk and/or FreeSWITCH in production
Real dial plan authoring and debugging, not just editing someone elses
Experience with SIP trunk providers and PSTN connectivity
Linux (good to expert level)
Command-line fluency
Systematic troubleshooting on an unfamiliar box under load
Networking knowledge: TCP/UDP behaviour, routing, DNS, NAT, firewalls, and how to prove where a packet is dropped
Troubleshooting (What matters more than the checklist) - You want to know why it broke and get to the root cause of the issue to fix it. You reach for the layer below when the obvious answer doesnt hold.

Good to have

Kamailio/OpenSIPS or SBC exposure
Ami/ari or ESL
Webrtc, tls/srtp
kernel tuning
any cloud platform, Python, or monitoring tool

Experience

2-4 years

Full time
