Senior Frontend Engineer

📣 Company: FANzino (iGaming) 📣 Position: Senior Frontend Engineer

🔎 About the company

FANzino is a B2B provider of new-format games in the online gambling world.

We are looking for a strong Senior Frontend Engineer to help create new live games and develop the overall game engine. You will work at the intersection of frontend, game development, real-time, and WebGL — from game logic and interface to complex animations and 3D bonus games. 🚀

The vacancy involves working from the office in Cyprus (Limassol) — we are building a strong team in one place to accelerate processes and improve collaboration.

💻 Responsibilities:

🔸 Build new games on the common game engine: game field, bets and chips, round history, win animations, and other game mechanics. 🔸 Develop 2D scenes using Pixi.js and 3D bonus games using Three.js / react-three-fiber, including work with custom GLSL shaders. 🔸 Integrate Rive animations and manage their state machine directly from game logic. 🔸 Synchronize the interface with the game round in real-time: game phases, bet acceptance, results, and payouts come via WebSocket, including correct handling after reconnection. 🔸 Develop and optimize the video player: work with latency, stream recovery, and quality metrics. 🔸 Ensure smooth and stable game performance on mobile browsers. 🔸 Collaborate with game and motion designers: integrate and bring assets to a production-ready state, as well as improve and simplify their workflow pipeline.

🛠 Technical Requirements:

🔹 Solid experience with React and TypeScript: hooks, Suspense, rendering optimization. 🔹 Practical experience with Canvas/WebGL and libraries like Pixi.js, Three.js, or equivalents. 🔹 Understanding of real-time interface construction principles: WebSocket, reconnections, handling out-of-order events. 🔹 Experience with state management: Jotai, Zustand, Redux, or equivalents. 🔹 Experience with writing tests: Vitest/Jest, Testing Library. 🔹 Understanding of frontend architecture and the ability to make independent technical decisions. 🔹 Ability to optimize the performance of complex interactive interfaces.

⭐️ Will be a plus ⭐️

🔹 Experience with Rive: state machines, inputs, events. 🔹 Knowledge of GLSL and experience writing/optimizing shaders. 🔹 Experience with browser video: HLS, WebRTC, MSE. 🔹 Experience optimizing rendering: batching, texture atlases, memory management on mobile devices. 🔹 Experience with Blender, exporting 3D models and animations.

🧑‍🤝‍🧑 Personal Qualities:

🔸 Ability to work in a team and effectively interact with developers, designers, and other specialists. 🔸 Responsibility for results and attention to detail. 🔸 Ability to independently tackle complex technical challenges and find solutions. 🔸 Ability to see tasks through to completion and be accountable for the quality of the results. 🔸 Proactiveness: you don't just complete assigned tasks, but suggest improvements and help develop the product. 🔸 Readiness to work with rapidly changing tasks and learn new technologies.

📣 Conditions 📣

🔸 Work from the office in Cyprus (Limassol). 🔸 Meal compensation in the office. 🔸 Official employment under Cyprus Labor Law. 🔸 4 additional days off. 🔸 No legacy — we are building the product and gaming platform from scratch. 🔸 Opportunity to influence the product's architecture and technical decisions.

If you are interested in creating high-load live games, working with WebGL, real-time, and modern frontend architecture — we would be happy to meet you!
