Want to bring your contribution to the only fully functional WebRTC over SIP stack in the world? If yes, we're ready to take you on our Frontend or Backend teams🚀

As our intern, you will discover how we provide support for the client level frontend (JavaScript and mobile) or you'll be dealing with a lot of experimental and newborn technologies like WebRTC, so JavaScript will become your playground. From simple storage to complex business logic, we're here to teach you how the backend works. We use JavaScript (Node.js), PHP, Java or Python and your days here will always be cool. Get ready to implement internal SDK engine for third-party developers and software clients that interact with the REST/WebSockets Cloud backend or to focus on JavaScript/HTML5 because browser apps deliver the portability advantage in the Cloud. Sounds challenging? Don't worry, mentors will be there to guide you every step of the way.
