Job description

We're looking for a strong Middle Frontend Developer who can think beyond a single game, at the level of the entire product portfolio. Architectural decisions, reusable components, shared pipelines: what you build affects multiple projects at once.

We're a team of people who left safe jobs to build something better. No bureaucracy, no pointless meetings — just sharp minds building games that stand out.

What you’ll do

• Build and ship slot games end-to-end — from initial prototype to production release;
• Beyond game development, participate in shaping the frontend architecture and development standards across all projects — making technical decisions, reviewing code, and sharing expertise with the team;
• Collaborate with Producers, Artists, and Backend Engineers to ensure seamless integration and optimized performance;
• Contribute to code quality through reviews and shared standards, keeping our codebases scalable, maintainable, and reusable;
• Contribute to the design and implementation of new features, UI components, and in-game effects;
• 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

• 3+ years of frontend development experience, including at least 1 year 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 or proficiency in Codex and WordCode is required;
• Fluency in English.

Nice to have

• Experience with game audio — Howler.js, Web Audio API, or similar;
• 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;
• Experience with Vue 3 or other modern UI frameworks.

• 21 vacation days + 5 extra day-offs annually;

• 12 paid sick days;
• Fully remote format — work from anywhere you feel productive;
• Flexible schedule: start your day anytime between 08:00–12:00 CET;
• Fixed budget for health insurance and gym/fitness;
• We provide all required work equipment;
• Zero bureaucracy and direct communication with founders and C-level;
• Minimal meetings, async-friendly workflow;
• Startup energy: fast motion, creativity, and tight-knit communication;
• Business trips and team meetups several times per year;
• Multiple salary payout options (flexible formats);
• …And many more perks unlocked after we hit break-even.
