Blockchain Developer (Solana, Rust, FastAPI)

• Design, develop, and deploy smart contracts on Solana (using Rust and Anchor if appropriate) to manage game rewards and payment logic.
• Build and maintain backend services (preferably FastAPI) to connect the game server with the blockchain — including transaction signing, tracking, and handling webhooks or callbacks.
• Integrate Solana/SPL Token wallets, ensuring secure and efficient reward transfer processes.
• Implement robust security measures to prevent replay attacks and double spending, and ensure proper access control, rate limiting, and logging.
• Prepare technical documentation, and support QA/UAT testing and post-launch maintenance.
• Collaborate closely with the Game and Frontend teams to ensure smooth gameplay and rapid resolution of production issues.

MUST HAVE SKILLS:

• Solana: Proven experience deploying production-ready smart contracts.
• Rust: Skilled in writing, optimizing, and auditing smart contracts.
• FastAPI (or equivalent): Experience building off-chain services interacting with the blockchain.
• Strong communication skills with fast response time to client messages.
• Proactive use of AI tools (e.g., ChatGPT, Copilot) for debugging, research, and problem-solving.

NICE TO HAVE

• Experience with Anchor Framework for Solana.
• Familiarity with game-related blockchain integration and reward systems.
