We are seeking a highly skilled, adaptable Senior Full-Stack Developer to join our company, a pioneering skill-based gaming platform that bridges high-performance Web2 competitive matchmaking with secure, decentralized on-chain settlement.

In this full-time remote contractor role, you will be responsible for building and scaling our Web2 backend services in Golang and our frontend user interfaces in React. Because our project operates a hybrid architecture, you do not need to write smart contracts daily, but you must possess a solid, intuitive understanding of decentralized systems, ledger mechanics, and Web3 integration patterns.

We encourage the use of AI-assisted development tools, however, AI is a multiplier, not a replacement for engineering fundamentals. You must possess the deep system-level experience required to critically evaluate, architect, debug, and optimize the code you deliver.

You Will Do

• Design, build, and maintain high-throughput, low-latency microservices in Golang.
• Develop responsive, highly responsive user experiences in React, utilizing modern micro-frontend design patterns and state management.
• Bridge our Web2 application layer with our Web3 protocols, ensuring seamless communication with non-custodial wallets and blockchain nodes.
• Apply robust web service architectures, ensuring optimal API performance, security, and message-queue reliability.
• Collaborate with product and technical leadership to rapidly iterate on new tournament mechanics, leaderboard systems, and payment integrations.

What We Are Looking For

• Proven, production-grade experience with Golang (Go) for backend microservices and React for modern web frontends.
• Strong knowledge of web service design patterns, API gateway structures, caching strategies, and frontend microservices.
• A clear, demonstrable understanding of Web3 environments, cryptographic signing, non-custodial wallet flows, and RPC node communication. W
• The ability to write clean, self-documenting code, design robust database schemas, and lead complex features from technical specification through to production deployment.
