Senior Playable Developer
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.
At Madbox, the Creative Studio produces hundreds of ad creatives every month across multiple game titles - and the operation is scaling fast. At Madbox, playable ads are one of the most powerful tools for driving installs.
As Senior Playable Developer, you will bring this in-house: building fast, high-performing interactive ads that give players a real taste of our games. You will create modular template systems, iterate rapidly on winning concepts, and establish an in-house playable production capability that reduces agency dependency. Most importantly, you have a strong sense of "game feel" - you know how to make interactions snappy, satisfying, and addictive.
Your future responsibilities and scope:
Develop interactive playable ads from concept to deployment across major ad networks
Build modular, reusable playable templates and component libraries for rapid iteration
Iterate on top-performing playables, enabling data-driven A/B testing of mechanics, hooks, and CTAs
Ensure cross-platform compatibility, meet size limits, load time requirements, and performance standards
Collaborate with the Creative Lead on concept development and with Tech Art on asset pipelines
Explore new interactive ad formats, evaluate AI-assisted playable generation tools, and stay current with playable ad technology
The profile we are looking for:
2-4+ years developing playable ads or interactive web content
Strong proficiency in JavaScript, HTML5, and CSS
Experience with playable ad frameworks or custom HTML5 game engines
Solid understanding of game development fundamentals (game loops, input handling, basic physics)
Familiarity with ad network specifications and constraints
Optimization mindset: file size, load time, frame rate
Comfortable with rapid prototyping and short iteration cycles
Regular use of AI-assisted development tools (e.g., Cursor, Claude Code)
Nice to have:
Experience with Canvas/WebGL experience
TypeScript
Phaser or similar frameworks
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 🙏
