Odos - Smart Contracts Engineer EVM

About the Role We're looking for a talented Backend / Smart Contract Engineer to help design and build the core infrastructure that powers Odos. You'll work on critical components ranging from backend services and APIs to gas-optimized Solidity contracts and on-chain logic. Your work will directly impact how users and protocols interact with DeFi at scale. What You'll Do - Design and develop backend systems that coordinate complex DeFi interactions, including trade routing, transaction simulation, and analytics. - Write, audit, and maintain robust, gas-efficient smart contracts in Solidity. - Collaborate with frontend and protocol teams to ensure seamless integration across the Odos stack. - Conduct performance profiling, optimize for gas costs and execution time. - Stay up to date with the latest DeFi protocols, standards, and smart contract best practices. - Lead and participate in code reviews, architecture discussions, and technical planning. - Contribute to cross-chain infrastructure and help expand Odos to new blockchains. - Write and maintain comprehensive documentation for internal and external use. 3+ years of professional backend engineering experience - Strong proficiency in one or more backend languages: Rust, Go, Node.js, or Python. - Experience designing scalable APIs, data processing systems, or infrastructure for financial or real-time applications. - 2+ years of hands-on experience writing smart contracts in Solidity • Proven experience deploying, testing, and maintaining contracts on Ethereum or EVM-compatible chains. • Deep understanding of smart contract security, gas optimization, and upgradeability patterns. - Solid understanding of DeFi protocols and primitives • Familiar with token standards (ERC-20, ERC-721, ERC-1155, ERC-4626), DEXes (Uniswap, Curve, Balancer), and lending protocols (Aave, Compound, etc.). • Ability to reason about complex on-chain interactions and liquidity mechanics. - Proficient with Web3 development tools • Experience using Hardhat, Foundry, Ethers.js, Web3.py, and related frameworks. • Comfortable simulating and analyzing Ethereum transactions. - Strong systems and architectural thinking • Ability to design systems that are performant, resilient, and maintainable across multiple chains and components. - Self-driven and collaborative • Thrives in a fast-paced, async-friendly startup environment. • Comfortable working independently and coordinating across functions (e.g., frontend, product, protocol).
