Blockchain Engineer

As a Blockchain Engineer at ScriptoFi, you will architect, develop, and ship secure, scalable decentralised applications at the frontier of Web3 and AI. You combine deep protocol-level expertise with a builder's mindset, working independently to build and ship features end-to-end. You integrate on-chain logic, off-chain systems, and DeFi protocol mechanics into production-grade decentralised applications, owning your feature surface from design through deployment.

What you'll do

• Design, develop, and ship smart contracts and on-chain features targeting Ethereum L1 mainnet, production-grade, audit-ready, and gas-optimised
• Build secure, efficient, and upgradeable smart contracts in Solidity with deep attention to vulnerability patterns and auditability
• Develop and maintain decentralised applications (dApps) with seamless Web3 wallet and Ethereum protocol integrations
• Implement token standards, governance mechanisms, staking systems, and DeFi protocol features such as lending, AMMs, and vaults
• Connect smart contracts with backend systems, REST/GraphQL APIs, and third-party infrastructure services
• Lead and participate in architecture reviews, technical discussions, and code reviews to maintain engineering excellence
• Maintain high standards for code quality, test coverage, security hardening, and technical documentation

What you bring

• 3+ years of professional software engineering experience with a strong focus on blockchain development
• Expert proficiency in Solidity with deep knowledge of EVM internals, contract patterns, and upgrade mechanisms
• Real Ethereum L1 mainnet experience with production deployments, not just testnets or L2s
• Hands-on experience building or contributing to a DeFi protocol such as lending, staking, or AMM
• Proficiency in JavaScript/TypeScript
• Experience with development and testing frameworks: Hardhat and Foundry
• Strong understanding of smart contract security, common vulnerability patterns, and auditing best practices
• Experience integrating wallets such as MetaMask and WalletConnect, oracles such as Chainlink, and Web3 infrastructure providers
• Proficiency with AI coding agents and multi-agent workflows as part of day-to-day engineering practice
• Clear written and spoken English, with the ability to document technical decisions concisely
• Eligible to work in the United Arab Emirates

Nice to have

• Working knowledge of Python, Go, or Rust
• Experience with EVM-compatible chains: Polygon, BNB Chain, Arbitrum, Optimism, or similar
• Experience with non-EVM chains: Solana, Aptos, Sui, Cosmos, or similar Layer-1 ecosystems
• Familiarity with Layer-2 scaling solutions, rollup architecture, and cross-chain bridging
• On-chain security monitoring, threat detection, and smart contract incident response
• Experience deploying and managing infrastructure on AWS, Azure, or Google Cloud Platform
• Exposure to DevOps practices, CI/CD pipelines, and automated smart contract deployment workflows
• Awareness of the UAE virtual asset regulatory environment (VARA/ADGM) and how compliance requirements shape protocol and product decisions
• Prior experience working in a Web3 team in the UAE or the wider GCC
