As of Jun 28, 2026, the average hourly pay for solidity programmer in the United States is $39.54, according to ZipRecruiter salary data. Most workers in this role earn between $25.72 and $51.44 per hour, depending on experience, location, and employer.

What are some common challenges Solidity Programmers face when developing smart contracts?

Solidity Programmers often encounter challenges related to security vulnerabilities, such as reentrancy attacks and integer overflows, due to the immutable and transparent nature of blockchain. Debugging and testing smart contracts can also be more complex compared to traditional software because of limited tooling and the need to simulate blockchain environments. Additionally, optimizing for gas efficiency while maintaining readability and security requires careful coding and regular code reviews. Collaboration with auditors, front-end developers, and project managers is crucial to ensure robust and user-friendly decentralized applications.

What are Solidity programmers?

Solidity programmers are software developers who specialize in writing smart contracts using the Solidity programming language. Solidity is primarily used on the Ethereum blockchain to create decentralized applications (dApps) and manage digital assets through self-executing contracts. These programmers are skilled in blockchain concepts, cryptography, and the unique security requirements of smart contract development. They work closely with blockchain architects, auditors, and front-end developers to ensure decentralized applications function correctly and securely.

What are the key skills and qualifications needed to thrive as a Solidity Programmer, and why are they important?

To thrive as a Solidity Programmer, you need a solid understanding of Ethereum blockchain principles, smart contract development, and programming experience with Solidity, often supported by a background in computer science or software engineering. Familiarity with development tools like Remix, Truffle, Hardhat, and version control systems such as Git, as well as knowledge of security best practices and relevant certifications, is highly beneficial. Attention to detail, problem-solving abilities, and effective communication help ensure code reliability and successful collaboration with team members. These skills are crucial for building secure, efficient, and trustworthy decentralized applications in the rapidly evolving blockchain ecosystem.

What is the difference between Solidity Programmer vs Blockchain Developer?

AspectSolidity ProgrammerBlockchain Developer
Primary FocusWriting smart contracts in SolidityDeveloping entire blockchain applications and infrastructure
Skills & CertificationsProficiency in Solidity, Ethereum, smart contract securityKnowledge of blockchain protocols, cryptography, and multiple programming languages
Work EnvironmentBlockchain projects, smart contract developmentEnd-to-end blockchain solutions, DApp development
Industry UsagePrimarily in Ethereum-based projectsAcross various blockchain platforms and ecosystems

While Solidity Programmers specialize in writing smart contracts using Solidity, Blockchain Developers have a broader role that includes designing and implementing entire blockchain applications. Solidity Programmers focus on smart contract coding, whereas Blockchain Developers handle the overall architecture, integration, and deployment of blockchain solutions.

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).
