## About You

As a VoIP Engineer you understand how the Telnyx Telephony Engine works as whole, while also being able to identify each underlying service and its purpose. You use this knowledge plus your experience working with VoIP technologies to design new features and guide software developers on their implementation. You assist other teams by triaging escalated issues and then working with all the involved parties until they are resolved. You are the subject matter expert for all topics that are telephony related, and when you don't know the answer you will know who to ask.

The Opportunity

You work with users around the globe, where you help by solving their communications challenges. You’ll also get to work with other engineers to build delightful features that span various parts of the system, as well as our business, sales, and operations teams to understand and solve our users’ pain points.

We’re looking for people with a strong background in VoIP technologies and interest in building successful products or systems; you’re comfortable in dealing with lots of moving pieces; you have exquisite attention to detail; and you’re comfortable learning new technologies and systems.

- Understand how all Telephony services work and how they are integrated to the platform.
- Operate, maintain, expand and support SIP proxies based on Kamailio or OpenSIPS applications.
- Handle level 3 troubleshooting escalations and triaging.
- Analyze telephony traffic patterns and identify issues and anomalies.
- React to critical alerts in order to rapidly return to a full-service state.
- Troubleshoot and resolve voice and network protocol communication issues.
- Interface with partner organizations for interconnections and expansions.
- Design, build, test, deploy and maintain monitoring, alerting, QA and logging tools for Telephony applications.
- Coordinate system maintenance and deployment events.

Who we're looking for

- A degree in Computer Science, Information Technology, Telecommunications or similar.
- Strong understanding of IP telephony (VoIP), TCP/IP Networks and related protocols (SIP, RTP, RTCP, ISUP, TLS, STUN, TURN, WebRTC).
- Experience with Open Source VoIP applications such as Kamailio, OpenSIPS, FreeSWITCH, RTPEngine, Asterisk and open source tools such as Wireshark, sngrep and Homer.
- Experience with Linux, Open Source tools and shell scripting.
- Experience with containers and automation/orchestration tools such as Docker, Ansible, Jenkins, Kubernetes.

- **AI Inference**: Edge-deployed GPU inference for voice and text AI, with per-token pricing or x402 pay-per-call.
- **Wireless (Mobile IoT)**: Programmable eSIM and roaming for IoT devices.

- **Global expansion**: Continues to add PoPs and data center locations (Amsterdam, Dublin, Warsaw, Bangalore, etc.) to reduce latency.
- **AI-native platform**: Building autonomous orchestration for agent-to-agent workflows and inference at the edge.
