About Telnyx
Telnyx is a growth-stage software company building a platform that facilitates mission-critical, real-time communications (RTC) accessible to anyone with an Internet connection.

Our strategy involves interconnecting with major ISPs in order to minimize latency, jitter and packet loss, thus mitigating the quality shortcomings entailed by the best effort nature of the Internet. Our network leverages direct cross-connects into major Cloud Service Provider networks for compute and storage resources, and private fiber to connect our global points of presence. The result is a homogeneous, cloud-agnostic (leveraging Google Cloud, AWS, Microsoft Azure, IBM Cloud) infrastructure on which to deploy our containerized services.

  • Handle Level 2 support escalations
  • Oversee telephony traffic patterns and handle critical alerts
  • Troubleshoot and resolve voice and network protocol communications issues 
  • Interface with partner organizations for interconnections and expansions
  • Design and implement tools for automated QA
  • Coordinate systems updates and deployments

What we're looking for
  • Degree in Computer Science, Information Technology, Telecommunications, and/or equivalent work experience
  • Strong understanding of IP telephony (VoIP), TCP/IP Networks and related protocols (SIP, RTP, RTCP, ISUP, TLS, STUN, TURN, WebRTC).
  • Experience with Linux, open source tools and shell scripting.

What we value
  • 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 containers and automation tools such as Docker, Ansible, Jenkins, Nomad is a plus .
  • Experience with Python, Elixir, or Go is a plus.


Bring your skills, experience, and interests. Help us to achieve our mission in democratizing RTC.
