Game Designer


Mediatonic is a leading independent developer, focused on building and operating live games.

We’ve been in business for 13 years and with a development team of over 120 people, we’re one of the largest independent studios in the UK.

With studios in both London, Brighton and Madrid, we’re committed to developing best in class titles that entertain millions of players.

Key Responsibilities

As a game designer at Mediatonic, you’ll be sat at the heart of one of our game teams; responsible for taking a game concept and mapping out the structure and systems that underpin it. You can expect to:

  • Create and maintain full game design documentation for assigned projects
  • Take a feature concept from a single slide overview and create clear, concise specifications that be easily understood by team members from all disciplines.
  • Design and balance the meta-systems and economies that sit behind our games.
  • Create high level overviews of new designs and concepts to quickly convey ideas both internally and externally
  • Map out data structures that allow for rapid tuning and iteration with minimal code changes.
  • Seek efficiency where possible; look to save time through natural cross-over, reuse or alignment of functionality for different game features.
  • Continuously look for ways to improve or expand on the game experience through creating ideas for new levels, mechanics or features.
  • Design levels, puzzles and challenges, making use of custom level editing tools and basic scripting
  • Troubleshoot and help solve design challenges or problems that arise during the game development process
  • Meet with team members to ensure that everyone understands the goal and plan for a feature design before its implementation
  • Review the implementation of features and new game mechanics to ensure they are fun, interesting, and align with the GDD

You are the game architect; responsible for ensuring it is built efficiently and to the highest possible standards.


We are seeking an experienced game designer who can jump in and immediately get their hands dirty. Ideally, you should have:

  • 3+ years game design experience in a studio environment
  • Proficient in Word, Powerpoint and Excel
  • Exceptional understanding of game structure and systems
  • Wide knowledge base of past and present games, across all genres
  • Able to communicate your ideas clearly, concisely and efficiently
  • Adaptable and able to quickly pick-up new skills and ways of working
  • Comfortable working closely with others and looking after creative teams
  • Exceptional ability to produce clear and workable documentation

It is important to note that this role will span both premium and free to play titles. It is important that you understand the differences between these two, enjoy both, and are comfortable working in either realm.

Why Choose Mediatonic?

  • You LOVE games and want to be surrounded by talented [super nice] people who share your passion for brilliant game experiences
  • You enjoy a rich variety of projects rather than working on a single franchise or business model for years at a time
  • You care about making a big impact on your projects and so you appreciate the beauty of working in smaller teams
  • You want to work on next generation platforms including Smartphones, Tablets, Steam, XBOX One and PS4
  • You enjoy the buzz of being based in the heart of Britain’s greatest cities!

Working Environment

Above all, we take pride in crafting games that challenge and inspire us every day.

We hire experts to take on the biggest creative and technical challenges we can get our hands on and we invest in our people for the long term.

Working in small and ambitious teams we strive for minimal hierarchy. Our philosophy is to be open in informal.

Our studios are based in the heart of central London, Brighton and Madrid. You’ll find plenty of social activities during and outside of work time including game nights, board game nights, life drawing classes, game jams, tech talks, pub trips and a visiting chef once a month who provides lunch for the whole company.

Games are fun! We believe if you have fun making them, it shows through in the final product.

Applying for this Role

We receive thousands of applications every year. As a small team we try our best to respond to everyone but we don’t always get this right. We know how hard it is to find the right role and we’re really grateful for every application we receive.

Here’s some advice when applying to Mediatonic…

A cover letter that tells us a bit about you and what you’re passionate about is essential to get our attention and distinguish your application from the crowd.

Read the job description carefully and let us know why you believe you’re the right person to take on this job; a huge part of Game Design is communicating your ideas to others.

Successful applicants will normally receive a written questionnaire followed by a phone interview. After this process, you’ll be invited to an interview at Mediatonic with members of our Creative team.

We look forward to hearing from you!
