Mobile App Developer Job Description Template

A mobile app developer uses programming languages and development skills to create, test, and develop applications on mobile devices. They work in popular operating system environments like iOS and Android and often take into account UI and UX principles when creating applications.

Share

A mobile app developer is able to create software for phones and tablets, and is familiar with the newest technologies in the mobile world. Mobile development requires staying in the mobile head space, meaning that it’s even more important than with other hardware contexts to optimize performance, battery, network, and memory management. A developer must be also aware of how to deal with device fragmentation, often working closely with a designer to achieve the best user experience (UX) results.

“Mobile app developer” is a very wide term, because it’s not limited to developers who write native code for platforms like Android and iOS. It can also include hybrid app developers working with frameworks such as Cordova or Ionic, and JavaScript and C# developers, who are using React Native and Xamarin to write mobile apps. These are distinct specializations, so it’s crucial to either specify what technology you intend to use in the app or make it clear that you are open to technology propositions.
