JavaScript Game Developer (Pixi.js)

We are looking for a JavaScript Developer to join the SlotCore team — the key technical hub responsible for the core of our slot games.

The team builds foundational features used across all games: from resource loading to bonus mechanics. They work with services like Helvix/Sven, integrate graphics, and manage how resources are handled.

This role is about deep technical work and long-term development — implementing changes that shape game structure, improve stability and performance, and lay the groundwork for new features.

Requirements

• 2+ years of experience with JavaScript (ES6+), PixiJS, Pixi-Spine, HTML5;
• Practical experience working with Spine animations;
• Understanding of resource management in web-based games — loading, caching, and updating graphic/media assets;
• Proficiency with Git version control;
• Solid grasp of code structure principles: modularity, event-driven architecture, and structured rendering.
  
  

Will be a plus

• Experience integrating with asset delivery services (like Helvix, Sven, or similar).
• Familiarity with performance optimization in WebGL/Canvas environments.
• Experience using task runners such as Gulp or bundlers like Webpack.
• Basic understanding of Figma for navigating design layouts.
  
  

Responsibilities

• Develop and maintain core components used across all slot games.
• Build and improve shared game mechanics such as resource loading, bonus systems, and essential UI features.
• Collaborate with services like Helvix/Sven to integrate game assets (graphics, audio, etc.).
• Contribute to the technical evolution of the client-side architecture that powers the company's slot games
