Solidity Engineer

Noble is building the AppLayer — an EVM L2 designed to power high-performance, high-impact applications — starting with our flagship DeFi app. We’re looking for a Solidity Engineer who can design, build, and ship secure, elegant smart contracts that will serve as the foundation for our ecosystem. You’ll work closely with Engineering, Product, and leadership to bring innovative DeFi functionality to life while ensuring security and scalability at every layer. Responsibilities: Design, implement, and maintain smart contracts for Noble’s AppLayer and flagship DeFi app, focusing on performance, scalability, and security. Collaborate with Product and Engineering to translate requirements into robust, gas-efficient Solidity code. Integrate new DeFi primitives, features, and protocols into the AppLayer environment. Lead contract architecture decisions — from design to deployment — ensuring alignment with security best practices and long-term maintainability. Write thorough test suites (unit, integration) to guarantee reliability. Collaborate with security auditors and incorporate feedback to harden deployed contracts. Monitor, optimize, and upgrade deployed contracts to adapt to evolving user needs and network conditions. Contribute to SDKs, developer tooling, and integration guides for external teams building on AppLayer. Stay up to date on EVM advancements, Solidity patterns, Layer 2 scalability solutions, and cutting-edge DeFi innovations.
