[（ 1 ） Smart Contract Engineer ]

About job 🌐 Company: DV Labs 🕹️ Project: Web3 GamerHub 📅 Timeline: 3 - 4 years 🌍 Location: Fully Remote

Role Summary The Smart Contract Developer at GamerHub will design, implement, and audit the blockchain-based systems that define player ownership, platform tokenomics, and subscription economies for our multi-chain aggregator. You will ensure the security, transparency, and scalability of all on-chain interactions, from NFT-based reward systems to automated subscription logic.

You will collaborate closely with our Backend, Frontend, and Product teams to bridge the gap between our high-performance Node.js services and decentralized protocols. Your work will directly empower millions of players to own their digital legacy and participate in a sustainable, trustless gaming economy.

---

Responsibilities • Contract Development: Design, develop, and deploy secure smart contracts in Solidity for platform tokens, tiered subscription systems, and NFT reward mechanisms.

• Protocol Integration: Collaborate with frontend and backend teams to integrate on-chain features into the GamerHub dashboard using Ethers.js or Web3.js.

• Economy Design: Contribute to the design of tokenomics systems, including staking pools, "Task-to-Earn" reward logic, and cross-game asset utility.

• Security & Optimization: Perform rigorous unit testing, security audits, and gas optimization for all contracts to ensure cost-efficient and exploit-proof transactions.

• Lifecycle Management: Manage contract versioning, deployments (Hardhat/Foundry) across various EVM-compatible testnets and mainnets (Ethereum, Polygon, etc.), and maintain upgradeable contract patterns (Proxies).

• Monitoring: Maintain live contracts to ensure 100% reliability and proactively identify potential vulnerabilities in the ecosystem.

• Documentation: Create comprehensive documentation for contract architecture and technical logic for both internal teams and external audit partners.

---

Required Skills & Qualifications

• Solidity Mastery: Deep proficiency in Solidity and a comprehensive understanding of the EVM (Ethereum Virtual Machine).

• Standards Expertise: Extensive experience implementing ERC-20, ERC-721, and ERC-1155 standards.

• Framework Proficiency: Strong background in Hardhat or Foundry for development, testing, and deployment.

• Web3 Integration: Solid experience using Ethers.js or Web3.js for frontend/backend integration.

• Security & Optimization: Proven track record of gas optimization and identifying common vulnerabilities (Reentrancy, Front-running, etc.).

• DeFi/NFT Knowledge: Deep understanding of decentralized finance protocols and the NFT ecosystem.

---

Preferred Skills

• Multi-Chain/L2: Experience with Layer 2 scaling solutions (Polygon, Arbitrum, Optimism) and cross-chain bridging protocols.

• Advanced Patterns: Knowledge of Solidity design patterns, UUPS/Transparent Proxy upgrades, and multi-signature wallet integrations.

• Non-EVM Literacy: Familiarity with Rust or Anchor for Solana development is a major plus, given GamerHub's multi-chain nature.

• Industry Experience: Prior contributions to high-traffic Web3 gaming or DeFi protocols.

[（ 2 ） Blockchain Engineer ]

About job 🌐 Company: DV Labs 🕹️ Project: Web3 GamerHub 📅 Timeline: 3 - 4 years 🌍 Location: Fully Remote

---

Role Summary The Blockchain Engineer at GamerHub builds and maintains the core infrastructure powering our multi-chain gaming aggregator. You will design and operate the secure, scalable systems that connect in-game assets, NFTs, and platform tokens across multiple networks.

This role focuses on on-chain infrastructure, RPC node operations, indexing services, and cross-chain integrations—the vital backbone that ensures our decentralized ecosystem remains fast, reliable, and transparent for a global community of gamers.

---

Responsibilities

• Infrastructure Management: Design and maintain the platform's blockchain infrastructure, including Solana and EVM RPC endpoints, nodes, and high-performance indexers.

• Middleware Development: Build robust middleware services in TypeScript or Node.js for seamless communication between our MongoDB backend and various blockchain networks.

• Cross-Chain Integration: Implement and optimize cross-chain functionality and data oracles to support multi-network compatibility for assets and identity.

• Data Indexing: Develop and manage subgraphs (via The Graph) or custom indexers to ensure real-time tracking of NFT mints, transfers, and reward distributions.

• Layer 2 Strategy: Evaluate and integrate Layer 2 solutions (e.g., Polygon, Arbitrum) to minimize transaction costs for users while maintaining security.

• Performance Monitoring: Monitor blockchain uptime and transaction latency across multiple environments, ensuring 24/7 reliability for the aggregator.

• Collaboration: Partner with the Smart Contract and Backend teams to integrate Web3 features like social-to-wallet onboarding and non-custodial asset management.

• Security & Standards: Enforce best practices for blockchain data handling, storage, and secure interaction with decentralized protocols.

---

Required Skills & Qualifications

• Experience: 4+ years in software engineering with a heavy focus on blockchain infrastructure and multi-chain systems.

• EVM Mastery: Strong experience with EVM-compatible networks (Ethereum, Polygon, BSC) and their underlying architecture.

• Tooling Proficiency: High proficiency in Node.js, TypeScript, Ethers.js, and Web3.js. • On-Chain Depth: Hands-on experience with RPC management, IPFS for decentralized storage, and indexing frameworks like The Graph.

• Infrastructure Mastery: Familiarity with Docker, Kubernetes, and automated CI/CD pipelines for blockchain services.

• Communication: Ability to design and document complex technical architectures for a remote, global engineering team.

---

Preferred Skills

• Non-EVM Knowledge: Specific experience with Solana (Rust/Anchor) and its unique data structures.

• Oracle Integration: Knowledge of Chainlink (VRF, Price Feeds) and other decentralized oracle protocols.

• Analytics: Exposure to Web3 analytics, block explorer APIs, and custom transaction monitoring tools.

• GameFi Background: Previous work on gaming aggregators, NFT marketplaces, or high-volume DeFi protocols.
