As a developer intern, you’ll design APIs, solve scalability challenges & write clean code for user facing tools. You bring solid knowledge of data structures and algorithms; you are familiar with Java and understand client-server architecture. But you will also craft responsive, seamless user interfaces and who also isn’t afraid to dive into different coding languages and technologies as needed. Knowledge of developing applications in GCP would be a bonus. 

Skills to create thrills 

You will ideally have an interest in games, and you should have the ability to work in a flexible and fluid environment, where the job will evolve over time.   

Tasty Bonus Skills: 

  • You should be a current student or recently completed your studies

  • Ability to use own initiative and motivation to meet deadlines and set priorities 

  • Passionate about building technology and games 

  • Proficiency in Java and/or Javascript
