Urgently Hiring Smart Contracts Developer information

What is the difference between Urgently Hiring Smart Contracts Developer vs Blockchain Developer?

AspectUrgently Hiring Smart Contracts DeveloperBlockchain Developer
CredentialsExperience with smart contract languages (Solidity, Vyper), blockchain platformsBroader knowledge of blockchain tech, programming languages, and infrastructure
Work EnvironmentFocus on developing, testing, and deploying smart contracts on blockchain networksDesigning blockchain solutions, developing decentralized apps, and infrastructure
Industry UsagePrimarily in DeFi, NFT, and blockchain project companiesIn various sectors including finance, supply chain, and tech startups

Urgently Hiring Smart Contracts Developers specialize in creating and deploying smart contracts on blockchain platforms, often requiring specific knowledge of languages like Solidity. Blockchain Developers have a broader role, including designing entire blockchain solutions and infrastructure. Both roles are vital in blockchain projects, but the Smart Contracts Developer focuses more on contract logic, while Blockchain Developers handle overall system architecture.

What are Smart Contracts Developers?

Smart Contracts Developers are software engineers who specialize in building, testing, and deploying self-executing contracts on blockchain platforms like Ethereum. These professionals use programming languages such as Solidity to create decentralized applications (dApps) and automate transactions without intermediaries. Their work ensures the security, accuracy, and efficiency of blockchain-based agreements across various industries, including finance, supply chain, and gaming.

What are the key skills and qualifications needed to thrive as a Smart Contracts Developer, and why are they important?

To thrive as a Smart Contracts Developer, you need a solid background in blockchain fundamentals, proficiency in programming languages like Solidity or Vyper, and experience with Ethereum or similar platforms. Familiarity with tools such as Truffle, Hardhat, Remix, and an understanding of smart contract security best practices or certifications like Certified Blockchain Developer are typically required. Attention to detail, strong problem-solving skills, and clear communication set top performers apart in this role. These skills and qualities are vital for building secure, efficient, and reliable decentralized applications in a rapidly evolving tech landscape.

What are some common challenges faced by Smart Contracts Developers when working on blockchain projects?

Smart Contracts Developers often face challenges such as ensuring code security, managing complex logic within the constraints of blockchain platforms, and staying updated with rapidly evolving technologies. Debugging and testing smart contracts can be difficult due to their immutable nature once deployed, making thorough code review and use of testnets critical. Additionally, developers frequently collaborate with product managers, auditors, and other engineers to align contract functionalities with project requirements and to conduct rigorous security audits.

Odos - Smart Contracts Engineer EVM

De Circle

San Francisco, CA • On-site, Remote

Full-time

Re-posted 20 days ago

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).
