We’re looking for a Playable Developer (Cocos Creator) to join our creative team.

What are you working on?

• Genres: Puzzle
• Platforms: Mobile, iOS, Android

For which tasks (responsibilities)?

• Build Playable Ads in Cocos end-to-end (gameplay loop, interactivity, UI, optimization, export for ad networks);

• Independently prepare assets from Unity projects: extract, optimize, and reuse assets effectively (e.g. avoid “render everything to video/PNG”);

• Create and evolve a Cocos playable starter kit/template: shared architecture, reusable components, standards, documentation;

• Iterate with UA/Creative (hooks/first seconds variations, A/B variants, improvements based on performance data);

• Collaborate with Creative Producers/Motion Designers on asset requirements, handoff formats, and checklists.

What kind of professional are we looking for?

• Strong Cocos Creator experience (solid TypeScript/JavaScript; good understanding of HTML5/WebGL);

• Solid 3D playable skills (camera/light/material basics, 3D scenes for HTML5/WebGL, awareness of WebGL 3D limitations);

• Solid 2D playable skills (nodes/prefabs, animation, state machines, input/physics, UI);

• Experience working with Unity, ability to independently extract and prepare all required assets from a Unity project for playable production;

• Proven experience shipping playables for multiple ad networks (e.g., Google Ads, Meta, Unity Ads, AppLovin) and understanding typical constraints;

• Strong playable performance optimization skills (build size discipline, load/first-interaction time, FPS/memory, atlasing/compression/profiling);

• High work autonomy, can take ownership from asset extraction to final exports without micromanagement;

• Spoken and written English and Russian.
  
  Nice to Have

• Understanding of UA concepts and why playables behave the way they do (CTR/IPM/CPI, first 3–5 seconds, pacing, traffic quality impact);

• Spine / DragonBones (or comparable skeletal animation workflows);

• Shader proficiency (Cocos Effect/Material system or Shader Graph equivalents where applicable);

• Experience diagnosing shader-related performance issues (overdraw, transparency, heavy fragment cost, reduce passes, avoid expensive features);

• Ability to profile and optimize for WebGL/HTML5 (CPU/GPU bottlenecks, memory spikes, draw calls/overdraw, texture formats, batching, light baking vs real-time tradeoffs, mesh/material consolidation);

• Asset pipeline optimization, strong understanding of texture compression, atlasing/sprite packing, mesh simplification basics, audio constraints;

• Ability to set up repeatable production workflows (project template, reusable components, export/build checklists, basic documentation);

• Experience migrating pipelines from a previous engine/framework to Cocos stack.

Why do we enjoy working here?

• The opportunity to work on games played by millions of players;

• Implement your bold ideas;

• Paid vacation;

• Support for professional development (training, coaching, and more);

• Opportunity to grow and develop with the company;

• Supportive and warm working atmosphere within the team.
