About us

Hi, we are Ten Square Games, and we live games! No, not a typo - but a level up from loving! We are on a mission of giving players excellent outdoor experiences on their mobiles. With global hits, such as Fishing Clash, we know how to make the best of technology, fun, and fair play. With 77 million registered players in 2024 and 300+ people on board, we keep growing and learning, having the insatiable hunger for the next success. If you also like to explore the unknown and know how to own it, we want to work with you!

What is this job all about?

We are looking for a highly autonomous Playable Ads Developer (f/m/d) to join our Creative Production team. You will be the sole technical owner of our interactive ad suite. Your mission is to transform game mechanics and creative concepts into lightweight, high-performance "mini-games" that drive millions of installs across global ad networks.

Why should you join us?

  • Creative Autonomy: You own the stack. No legacy code or lead developers to gatekeep your process - you decide the best tools for the job.

  • High-Velocity Impact: Your work goes live to millions. You’ll work directly with UA to see how your code impacts ROI in real-time.

  • The "Maker" Seat: This isn't a ticket-crushing role. You are a bridge between engineering and art, focusing on "juice," game feel, and innovation.

What will you be doing?

  • End-to-End Development: Take a creative concept from the design team and build the full playable experience from scratch.

  • Platform Optimization: Ensure playables meet strict "single-file" and size constraints (often <5MB) for Meta, AppLovin, Google, and more.

  • Asset Management: Work with 2D/3D assets, optimizing textures and animations for web performance without losing visual quality.

  • A/B Testing & Iteration: Quickly modify gameplay variables (difficulty, speed, CTA timing) based on performance data.

  • Technical Troubleshooting: Debug cross-browser and cross-device issues (iOS/Android) to ensure a seamless user experience.

What are we looking for?

  • Experience: 3+ years in game development or creative coding, specifically with HTML5-based engines.

  • Autonomy: Proven ability to work as a solo developer - setting up your own pipelines and solving technical roadblocks without a lead dev.

  • Tech Stack: Proficiency in JavaScript/TypeScript. Experience with web-native engines like Cocos Creator, PlayCanvas, or Phaser.

  • Network Knowledge: Deep understanding of MRAID and specific ad network technical requirements.

  • Creative Eye: You don't just "code to spec" - you understand what makes a game feel "juicy" (animations, particles, haptics).

We believe that work is much more than the benefits that you receive, although we have quite a few of those:

  • Clear career path & internal mobility;

  • Tailored language lessons;

  • Individual and team training budget;

  • Relocation package;

  • Choice of hardware - win or mac – take your pick;

  • Stay in the game - program for moms;

  • Free breakfast;

  • Concierge service - to make your life easier;

  • In-office massage;

  • Psychological support;

  • Worksmile cafeteria of benefits - individual fit;

  • CSR impact activities.

At Ten Square Games, sustainability is at the heart of how we play.
We’re not just here to make games – we’re here to make a difference. From inspiring climate awareness among players to supporting nonprofits and putting actions that mitigate our climate impact into place, we’re all in. We’ve built an inclusive workspace where every voice counts, bringing fresh ideas to the table and shaping the future of gaming for all. With a merit-based recruitment approach, we welcome everyone ready to help us level up.
