You’ll collaborate closely with designers and product leads, iterate quickly on new ideas, and see the direct impact of your work in the hands of players around the world.

If you enjoy mixing imaginative front-end polish with just enough back-end know-how to make the magic happen, we’d love to hear from you.

Key Responsabilities:

• Transform design mock-ups and product concepts into polished, responsive game screens, animations, and flows.
• Collaborate daily with designers, product leads, and blockchain engineers to prototype, ship, and iterate on new games or new features.
• Continuously test, debug, and optimize for performance across devices and network conditions.
• Review code, share best practices, and help keep our small codebase clean, secure, and easy to extend.
• Use player feedback and analytics to refine existing features and guide new ideas from concept to launch.
• Champion accessibility and web-standards compliance, ensuring every player—regardless of device or ability—has a first-class experience.

What You’ll Be Building

• Build interactive mini-games that deliver smooth, responsive gameplay.
• Create real-time multiplayer features and live game mechanics.
• Develop pack-opening systems with eye-catching, engaging animations.
• Engineer raffle and lottery-style games that are fully on-chain and provably fair.
• Implement Plinko and other physics-based games, tuned for fun and balance.
• Craft user-friendly interfaces that perform flawlessly across mobile, tablet, and desktop.

Requirements

• Observability: Grafana · PostHog
• Design & Web3: Figma · viem / wagmi

What We're Looking For

• Solid understanding of React and Next.js ecosystem
• Experience building real-time applications with WebSockets
• Familiarity with Node.js backend development
• Knowledge of PostgreSQL and database design
• Experience with responsive design and mobile-first development
• Understanding of state management patterns (Zustand experience preferred)
• Understanding of web security fundamentals (CSRF protection, secure authentication flows, input validation)
• Interest in gaming mechanics and interactive user experience.

Nice to Have

• Experience with gaming or interactive application development
• Knowledge of blockchain technologies and Web3 integration
• Familiarity with monitoring tools (Grafana, PostHog)
• Experience with Docker and containerization
• Understanding of real-time multiplayer game architecture
• Work From Home

Company Description:

Winnables.com is on a mission to re-imagine iGaming through full on-chain transparency. We believe players deserve provably fair odds, transparent math, and no black-box RNGs. Every spin and ticket purchase is recorded immutably on Ethereum, so anyone can audit the outcome, track prize pools, or even build their own analytics on top of our contracts.

All of our games are designed and engineered 100% in-house by a small, senior team that blends game design, cryptography, and smart-contract security. We currently operate two flagship experiences:

• Raffles – transparent prize drawings where every ticket lives on-chain, letting players verify fairness before and after the draw.
• Loot Packs – blockchain-powered loot boxes that reveal randomized rewards with engaging pack-opening animations.

We’re still just getting started. The roadmap is full of green-field challenges—and real, measurable impact on an industry ripe for change. Join us and help craft the next generation of fair, fun, and truly player-owned gaming.

Please note that if you are NOT a passport holder of the country for the vacancy you might need a work permit. Check our Blog for more information.
