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.

Requirements

🧩 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.

đź’Ž 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.

đź§  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.

Benefits

  • 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.

OptiPlay (operating under optiplay.io, legally OptiPlay) is the premier, next-generation iGaming software provider, game mechanics pioneer, and digital slot design studio engineered to act as the definitive, high-velocity math-driven engine, platform integration, and real-time gaming telemetry layer for digital casino operators and global gaming networks. Founded in 2025 by an elite group of veteran iGaming industry architects, the studio completely eliminates the severe systemic friction of modern online casino platform scaling—where operators encounter sluggish game load times, low-fidelity graphics transitions, and rigid, slow-to-adapt mathematical frameworks—by deploying its high-performance proprietary Proprietary Gaming Server (PGS) core. Moving far beyond traditional, legacy video game development pipelines or template-based gambling modules, OptiPlay natively unifies complex real-time game logic, bold 2D animations, cutting-edge RNG (Random Number Generator) integrations, and seamless multi-region API delivery into a high-availability, low-latency gaming infrastructure. Operating with an lean, async-first startup culture, the enterprise focuses on building high-impact slot games built to scale effortlessly across distributed cloud platforms. Under the hood, its technology framework utilizes advanced Node.js and TypeScript microservices built on high-performance frameworks like Fastify and NestJS, optimized caching strategies with Redis, robust message brokers via RabbitMQ or Kafka, and real-time dual-communication pipelines using WebSockets to process massive transactional gameplay logs and jackpot updates with absolute sub-second execution accuracy and regulatory compliance. What sets OptiPlay apart is its uncompromising dedication to replacing standard, high-overhead corporate software development with sharp mathematics, lightning-fast execution speed, and absolute ownership of the player journey; by bridging the gap between performance-intensive backend systems design and highly immersive visual experiences, the studio remains a definitive cornerstone of modern algorithmic iGaming software and global digital slot transformation.
