About Flexion Mobile Plc

Flexion Mobile is a leader in one of the fastest and biggest sectors of entertainment - mobile games! We are a dynamic and experienced team in London and Budapest who have set ourselves the goal to improve and change the mobile games industry forever. We help game developers and distribution channels generate more revenue from games by expanding reach and distribution. We went public on Nasdaq in Stockholm last year and since then we have been picked by Prolific London to be in the top 5 most valuable London based gaming startup.

At the core of our business is our patented technology that makes it possible to add, modify or remove features in compiled games to make them compatible with the requirements of any store without source code change. The technology does not require game developers to do any redevelopment work and does not require access to the game’s source code. It can enhance existing applications by adding features and functionality, such as gifting, in-app billing and several other solutions, primarily to drive revenue and user engagement.

If you are looking for an exciting technology challenge in a fast growing but still small and agile company - Flexion Mobile is the company for you. We are now looking for an enthusiastic, experienced individual to join our team in Budapest, Hungary.
