Remote Smart Contracts Developer information

What is the difference between Remote Smart Contracts Developer vs Blockchain Developer?

AspectRemote Smart Contracts DeveloperBlockchain Developer
CredentialsKnowledge of Solidity, Ethereum, smart contract securityIncludes blockchain architecture, cryptography, and development skills
Work EnvironmentPrimarily remote, focused on smart contract coding and deploymentRemote or on-site, broader blockchain system development
Industry UsageUsed in DeFi, NFT platforms, and dAppsUsed across blockchain projects, including infrastructure and applications
Search & Comparison IntentOften compared for smart contract-specific rolesBroader blockchain roles, but overlaps with smart contracts

Remote Smart Contracts Developers specialize in coding and deploying smart contracts on blockchain platforms like Ethereum, focusing on security and efficiency. Blockchain Developers have a broader scope, including designing blockchain architecture, developing protocols, and integrating smart contracts. While both roles require blockchain knowledge, smart contracts developers focus more on contract logic, whereas blockchain developers work on the overall blockchain system.

Job description

About Us
Odos (odos.xyz) is a smart order routing (SOR) solution that allows users to trade digital assets across decentralized exchanges. Launched in May 2022, Odos is available on 15 EVM chains and uses a patented algorithm to deliver the best swap rates to retail and institutional traders. Our multi-token swap feature allows users to trade many tokens in a single atomic transaction, and our newly launched intent based order types are leading the way in advancing the Web3 user experience. We are headquartered in Los Altos, CA (SF Bay Area).
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).
