In your role as a mobile app developer, you will be responsible for improving our open source Vialer apps, taking into account maintainability, scalability and stability. You are expected to have a strong vision on mobile development in general and on iOS in particular. Your focus will be on iOS, but a basic knowledge of Android development will help to keep the apps moving at the same speed.
We are currently working on the integration of encrypted calling, video calling, and converting the codebase from Objective-C to Swift. But, since we are a fast moving company, there is no telling what challenges will be around the bend.
If you are not already working in telecommunications, you will be introduced to the fascinating world of Voice over IP (VoIP) and the Session Initiation Protocol (SIP) that underlies most digital communication. We've created our own open source library that we maintain and support: the VialerSIPLib, that we use to integrate PJSIP with iOS. You are encouraged to share your knowledge with the open source community.
If you recognize yourself in the following profile, we might be a good match!
You have several years experience in iOS development in Objective-C and/or Swift
