What It Is Like To Work At Telnyx
Telnyx is a complex machine with a simple purpose: connect people. We are an intelligent telephony engine, the beating heart of the Telnyx service that routes data along the pathways of our global, private network. We are drop-in APIs for hooking applications into our products, and an administrator portal that puts unprecedented control of configuring and orchestrating the Telnyx service into our customers' hands.
We're also an organization of industry experts and engineers focused on solving problems and building solutions. We're a concierge customer success team and a 24/7 support team. We're a communications partner, focused on agile and endless innovation, not a telecom slogged in antiquated processes and anti-competitive regulation. We keep the conversation going: the always-on, omni-channel, enriched conversation that the modern world demands.
Communications are coming untethered from devices, and more and more, they're migrating into our everyday platforms: our social media, our work applications and our collaboration tools. But, that move started before there was infrastructure to support it—the modern internet will never offer the speed and consistency that real-time communications require. So, we built a network that does and a cloud platform tuned for real-time communications at every layer. Telnyx is the connective matrix, a worldwide nervous system, a high-speed rail tunnelling through the information superhighway. We're the foundation for calls, texts and messaging today, for the internet of things, augmented reality and "communitainment" tomorrow, and for whatever enterprising imaginations can dream up after that.
We're Telnyx. We're the future of communications.
