.net/C#/mono/objective-c UK based software project

We currently run [login to view URL] (HMA) a rather comical brand that operates the most visited browser based web proxy with 6-7 million visitors per month, and a VPN service with tens of thousands of subscribers. VPN services enable you to add an additional layer of security onto your internet connection in the form of encryption, this encryption ensures that your sensitive web traffic can not be intercepted by hackers on insecure networks (such as public wifi). Other benefits include the ability to change your online identity and IP address, virtually reside in another country to access GEO restricted content, bypass censorship, surf anonymously online, etc. More information can be found on our VPN pages [login to view URL] & [login to view URL] You may also want to check out some of our competitors with 'less crass' names; [login to view URL], [login to view URL], [login to view URL], [login to view URL], [login to view URL] We are looking for a software developer to lead the development of our HMA! Pro VPN service and our new sister-brand (yet to be announced). You will be responsible for improving and maintaining our current VPN client for Windows, Mac, and Linux Operating Systems, as well as developing new applications such as iOS/Android apps and router firmware. ## Deliverables Hi, We currently run [login to view URL] (HMA) a rather comical brand that operates the most visited browser based web proxy with 6-7 million visitors per month, and a VPN service with tens of thousands of subscribers.
