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.

In July 2022, we launched our Pocket Champs game worldwide, which quickly became one of the top-grossing games in its category. In our fast-paced, tech-driven environment, we continuously innovate by developing and updating our proprietary modules, along with integrating third-party ones, to enhance game functionalities, ensure precise analytics, and comply with evolving regulations.

This dynamic ecosystem requires meticulous coordination to keep our games at the forefront of technology and user experience.

As a Senior Game Developer, you will create innovative gameplay experiences and help scale them into potential hits. Working in a small, experienced team, you will contribute directly to shaping new game ideas from early stages.

If you are passionate about making games and enjoy building from the ground up, we would love to hear from you.

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 for:

  • Proven ability to deliver high-quality systems quickly and efficiently, without 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, Addressable and Optimisation for Mobile.
  • A true appetite for AI, an 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 is a big plus.
  • Previous experience in scaling a mobile game.

Please note: unfortunately, this position is not open to relocation and we cannot offer visa sponsorship.

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 🙏
