Job description

We are a technology start-up building the future of communication.

Voice calling has been the staple of distance communication since the first phone call in 1876. We believe that the calling experience for users has stayed more or less unchanged for past decades. We\'re working to fix it.

In our mission to help people communicate more efficiently, we have decided to build a calling platform - QTalk - that goes beyond just Voice and Video calling and empowers users with the tools to engage with each other in ways analogous to how they would interact in the real world. How often do you you meet a friend or family member and just look at each other and talk? No, you immerse yourselves in a shared reality, watching a video together, listening to music, playing games, and eating. QTalk aims to give you the same experience through the window of your smartphone.

It promises to be a fun ride. Come join us! Find out more about us at and our product here at
