Client-side Game Developer (Pixi JS)

Heaven of 7, part of VeliTech Group, doesn’t mass-produce games – we craft experiences that matter. Every project we build respects the player’s time and intelligence, combining purpose-driven mechanics with stunning visuals that create genuine moments of excitement.

As our Client-side Game Developer (Pixi JS), you’ll shape how players experience our games. Working with Pixi.js and our custom engine, you’ll lead the technical vision that brings our bold, high-fidelity 2D worlds to life. From dynamic multipliers to interactive bonus features, you’ll ensure every interaction feels smooth, responsive, and rewarding.

We’re looking for someone who balances creativity with discipline, collaborates openly, and takes pride in shipping polished, purposeful work. If you care about the bigger picture and want to help shift the industry from mass production to quality-first creativity, let’s talk.
