France · Full-time · Mid-Senior

Madbox is a fast-growing mobile gaming company with a very unique way of developing games. Everything has been made for teams to take as much ownership as possible, unleash their creativity, bring performance, and have as much fun as possible.


We're excited to open a brand-new studio in Annecy, a beautiful city nestled in the French Alps, perfect for fostering creativity. As part of Madbox, our Annecy studio is built on the same foundational pillars as our other game studios: creativity, collaboration, and innovation. We're seeking passionate mobile game enthusiasts to join our core team, where you'll have significant ownership and a huge impact on shaping our projects. You'll collaborate with former members of the team behind Pocket Champs, our first casual hit, helping to build something extraordinary from the ground up.


At Madbox, our core belief is that great team chemistry and a vibrant creative environment lead to exceptional games. These values drive our commitment to developing mobile games that are casual, unique, accessible, and inclusive, ensuring that every project embodies the spirit of our studio pillars.


As a Senior Game Developer, your mission will be to create innovative gameplays and to push them to scale so they can be the next hit of tomorrow. Working in a small team of experienced developers, designers, and artists, you’ll help bring our creative visions to life while developing your own skills.


If you’re passionate about making games and you have an entrepreneurial mindset, join us in this new adventure!


Your future responsibilities and scope:

  • Develop gameplay features with the scaling of the game in mind, including coding, testing, and debugging
  • Write clean, efficient, and self-explanatory code
  • As a game maker, create and iterate on innovative prototypes with scalability in mind
  • Collaborate closely with designers, artists, and other developers to help create cohesive and engaging game experiences
  • Support and contribute to new ideas or gameplay improvement


The profile we are looking:

  • Proven ability to deliver high-quality systems quickly and efficiently, while remaining agile
  • Have clean coding principles in mind and an ability to write sustainable systems
  • Be a true game maker, have a sense of game feel, and be passionate about making games
  • Innovative and entrepreneurial mindset
  • Strong knowledge in Unity, including UI, 3D, Addressables, and optimisation for mobile
  • A true appetite for AI, and experience using Claude for code generation, is a big plus
  • Understanding of other game development disciplines, including Design and Art
  • Humble and transparent posture, able to give and receive constructive feedback across all areas
  • Passion for mobile games

Nice to have:

  • Experience manipulating Shaders and FXs in Unity
  • Previous experience in scaling a mobile game


About relocation: Moving comes with a lot to think about, so we’ll take care of the tricky parts. With visa sponsorship, relocation support (yes, pets included!), and housing hunting - our goal is simple: help you land smoothly, feel at home quickly, and enjoy life in Annecy!


At Madbox, we value the mindset and how you can fit with our culture by sharing common values and creating great games together.

We are passionate, always pushing to the next level to learn new things. We are creative and innovative, and most of all, team players 🙏
