Node.js Jobs in Web3

Responsibilities

• Solidity Smart Contracts: Write Rome’s core Solidity smart contracts for state commitments, DA, settlement, bridging, etc.
• State Commitments: Post Rome’s state commitments such as Merkle roots to the base layer (Ethereum) blockchain to ensure robust transaction ordering.
• Data publication: Post Rome’s transaction batches and blocks to Ethereum and other DA Layers such as Celestia.
• L1 <> L2 Integration: Integrate base layer (Ethereum) withdrawals and deposits to allow bridging assets to Rome rollups, and prevent double-spending.
• State Synchronization: Ensure rollup state is synchronized between Solana and the rollup node. Develop code to address blockchain reorgs on Ethereum and Solana.
• Integrate Proofs & Settlement: Generate proofs including fraud and ZK, and post these proofs to Rome’s smart contracts.
• Ethereum Rollup Proficiency: Become proficient in Ethereum Rollup technologies including Arbitrum, Optimism, Polygon, and zkSync, preparing for tasks such as deployment, operation, debugging, and improvements.
• Zero Knowledge VM Expertise: Develop an understanding of Zero Knowledge VM and tackle the complexities of working with ZK-EVM stacks and integrating them with sequencers under various proving standards.
• Rome RaaS: Develop Rome’s Rollup-as-a-service by integrating various Ethereum clients such as Arbitrum Orbit, Polygon zkEVM, etc.
• Innovation in Rollups: Drive innovation within Rollup ecosystems by developing and implementing new features like Decentralized Sequencing, peer-to-peer messaging, and minimized trust off-chain computation.
• Network Security Enhancement: Improve network security and robustness by identifying potential vulnerabilities, setting up reproducible test environments, and developing strategic solutions.

Requirements

• Technical Proficiency: Proficient in writing core Solidity smart contracts.
• Blockchain Architecture Knowledge: Deep understanding of Ethereum client architecture, particularly its EVM execution client, Geth.
• Rollup Technology Familiarity: Familiarity with various Ethereum Rollup clients, their components, and the trade-offs involved.
• Independent Work: Capable of working independently from conceptualization to implementation, including monitoring and updating your own code.
• Communication Skills: Proficient in English, with strong skills in both writing and speaking.
• Code Quality: Proven track record of delivering high-quality, production-grade code, managing significant user interactions or transactions.
• EVM Integration Skills: Comprehensive knowledge of the EVM and its integration with external tools.
• Web3 Experience: Proficient with Web3 libraries and backend development (e.g., ethers and web3 libraries.
• Industry Passion: Keen interest in the Web3/crypto industry and user experience with crypto applications (e.g., Uniswap, Aave).
• Educational Qualifications: Bachelor's degree or higher in Computer Science, Software Engineering, or a related technical field.
