Our backend platform teams provide back-end framework and tools to run King’s games at scale on Google Cloud infrastructure. You will be involved in development of core backend functionality for King games and other backend services as part of an autonomous team collaborating with other platform teams and game teams. You will be part of the team process in design, planning, backlog refinement, stand-ups and retrospectives. You will also be part of the development process like code reviews, pair- and mob-programming and DevOps practices. As a backend developer intern, you’ll design APIs, solve scalability challenges & write clean code for game functionalities. You will also help solve scalability challenges to support the growth of King games. You bring solid knowledge of data structures and algorithms, you are familiar with Java and understand client-server architecture. Curiosity in Machine Learning and a bit of Python knowledge it's considered as a plus. 

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 
  • Excellent communication skills in English and great organization skills 
  • Creative problem-solving skills 
  • The ability to work well, both autonomously, and as part of a larger team 
  • Attention to detail and accuracy 
  • Proactive, enthusiastic, and results driven with an openness to feedback 
  • Ability to use own initiative and motivation to meet deadlines and set priorities 
  • Passionate about building technology and games 
  • Proficiency in Java 

The skills listed above are intended to portray the range of roles we have available; you do not need to possess all of these skills to apply! We will look at your own individual skill set and determine which team you would be best suited to. 

The brilliant experience we give our players comes from the diversity and experience of our people. A great saga needs all sorts of heroes. That’s why we hire all sorts of talent. 

We love hearing from anyone who is enthusiastic about changing the games industry. Not sure you meet all qualifications? Let us decide! Research shows that women and members of other under-represented groups tend to not apply to jobs when they think they may not meet every qualification, when, in fact, they often do! We are committed to creating a diverse and inclusive environment and strongly encourage you to apply.
