- Improve our core framework, build tools, and asset pipelines;
- Profile performance and debug across platforms (desktop, mobile, WebGL) to keep games running smoothly everywhere;
- Treat knowledge as a team asset — document your work and share what you learn with the team;
- Stay curious about modern frontend technologies and trends in the iGaming ecosystem.

💎 What you bring
- 4+ years of frontend development experience, including at least 2 years building HTML5 slot games — enough to have shipped multiple titles end-to-end and learned from real production cycles;
- Strong expertise with Pixi.js and modern JavaScript / TypeScript;
- Solid understanding of OOP, asynchronous programming, and rendering performance optimization;
- Strong knowledge of Spine animations and deep understanding of asset management pipelines;

- Experience with build automation, CI/CD pipelines, or process optimization tools;
- Familiarity with iGaming specifics: RNG logic, platform workflow, integrations.
- Experience with GLSL/WebGL shaders for custom visual effects;
