Odos - Smart Contracts Engineer EVM

As a Backend / Smart Contract Engineer at Odos, you'll help design and build the core infrastructure powering a smart order routing solution available on 15 EVM chains. You'll work on critical components ranging from backend services and APIs to gas-optimized Solidity contracts and on-chain logic, directly impacting 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 and 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

What you bring

• 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, including token standards (ERC-20, ERC-721, ERC-1155, ERC-4626), DEXes such as Uniswap, Curve, and Balancer, and lending protocols such as Aave and Compound
• Ability to reason about complex on-chain interactions and liquidity mechanics
• Proficiency with Web3 development tools including Hardhat, Foundry, Ethers.js, and Web3.py
• Comfort simulating and analyzing Ethereum transactions
• Strong systems and architectural thinking to design performant, resilient, and maintainable systems across multiple chains and components
• Self-driven and collaborative approach, comfortable working independently and coordinating across functions such as frontend, product, and protocol teams
