Middle Frontend Developer / Pixi.js
Optiplay · Remote, Slovakia
About The Role
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.
