  • Fixing and improving the code as necessary in light of testing
  • Collaborating with designers and other computing professionals to improve the app
  • write accurate notes about the development process
  • keep up to date with new technology trends and tools


You’ll most likely need:

Entry Requirements:

Employers generally look for technical skills and experience above everything else, and you should be able to provide evidence of these things. For example, you should be able to show off programs you have created/worked on and discuss what programming language(s) you used. (Useful languages include Java, Kotlin, and C/C++, although different languages might be better suited to different platforms.)

Some employers may also ask for a degree in a relevant subject, such as the following:

  • Computer science
  • Mathematics
  • Applied computing
  • Software engineering

You may be able to enter this career through studying for an apprenticeship. This is also a good way to build your skills.

Working Hours and Environment:

You’ll usually work traditional office hours: 9–5, Monday to Friday. You may sometimes need to work evenings and weekends if you’ve got to hit a tight deadline on a special project. You may also occasionally need to attend meetings or other events outside normal working hours.

Career Path & Progression:

Like other digital media roles, you can (and maybe should) learn a lot and develop many useful skills through downloading the relevant software and following online guides (and experimenting with the tools yourself). Keep a record of anything you create so you can show potential employers.

The computing sector is constantly changing and expanding, so there are always new opportunities and new areas to get into.

You could specialise in a certain field, like making banking apps, gaming apps, or educational apps. (It would be useful to have relevant qualifications if you wanted to specialise like this.)

You could become an expert in one particular programming language (although this may also have drawbacks – sometimes it’s good to understand a variety of languages for different situations).

With more knowledge and experience, you could move into management and be in charge of entire projects and/or your own team of programmers.

You could alternatively work on a self-employed basis, providing services and consultation to many different companies. As with all self-employment, there are advantages and disadvantages to this.
