You will pay special attention to the compatibility of the applications to ensure that they are supported and fully functional and ultimately, it is your responsibility to form interfaces that consistently improve the user experience.

Why consider a career as a Mobile (iOS/Android) Developer?
As a professional Mobile Developer, you can work directly for one company or for an agency. Entering the mobile application development field means that you are setting yourself up for success now and further down the line. As technology inevitably continues to modernise, your role will account for a high percentage of usage in the industry - due to mobile and tablet devices accounting for the majority of internet usage.

Generally, you’ll have live apps within the Play store and a natural interest in picking up the latest technologies and development techniques.

You'll be unit testing and proficient with GIT version control. You’ll be translating designs and wireframes into high-quality interfaces and devising the architecture and best approach for Android app development.

You’ll be designing, building and maintaining high performance, reusable and reliable Java code and identifying and fixing bottlenecks, bugs and reviewing any crashes. In addition, you’ll be called upon to attend client meetings and give regular updates on progress and also any industry events.

iOS Development: You’ll be interacting with teams including product developers, electronics engineers, embedded software engineers and Cloud developers to ensure connected solutions are functional, secure and easy to use.  

If experienced, you'll have apps to show from commercial native iOS app development using Objective-C or Swift. You will be a user of TDD / BDD development methodologies and have some experience of writing automated unit and UI tests (e.g. Catch, XCTest & Calabash). You'll be familiar with Atlassian tools including JIRA, Bitbucket & Bamboo and have experience/awareness of iOS build tools (e.g., xcodebuild, fastlane & CocoaPods).
