How much do solidity smart contract developer jobs pay per hour?

As of Sep 15, 2026, the average hourly pay for solidity smart contract developer in the United States is $58.08, according to ZipRecruiter salary data. Most workers in this role earn between $50.48 and $65.14 per hour, depending on experience, location, and employer.

What is a Solidity smart contract developer?

Solidity Smart Contract Developers are professionals who specialize in writing, testing, and deploying smart contracts using the Solidity programming language, primarily for the Ethereum blockchain. They design secure, automated agreements that execute specific actions when predefined conditions are met. Their responsibilities include auditing code, optimizing contract efficiency, and ensuring the security and reliability of decentralized applications (dApps). These developers play a crucial role in the blockchain ecosystem by enabling trustless interactions and decentralized finance (DeFi) solutions.

What are the key skills and qualifications needed to thrive as a Solidity smart contract developer?

To thrive as a Solidity Smart Contract Developer, you need a strong understanding of blockchain fundamentals, proficiency in the Solidity programming language, and experience with Ethereum-based development. Familiarity with tools like Truffle, Hardhat, Remix, and version control systems, as well as knowledge of smart contract security best practices and relevant certifications, is often expected. Attention to detail, problem-solving skills, and effective communication help developers navigate complex logic and collaborate with cross-functional teams. These capabilities are crucial for building secure, reliable, and efficient smart contracts that power decentralized applications.

How does a Solidity smart contract developer typically collaborate with auditors and other team members during the development process?

Solidity Smart Contract Developers work closely with auditors, project managers, and frontend engineers to ensure contracts are secure, efficient, and user-friendly. During development, they often participate in code reviews, provide detailed documentation, and address vulnerabilities identified by internal or external security audits. Effective communication and openness to feedback are essential, as developers must explain their logic and quickly implement recommended changes. This collaborative approach helps ensure the reliability and safety of deployed smart contracts, which is critical in blockchain environments.

Full-time

Re-posted 29 days ago

Key responsibilities

  • Design, implement, and deploy secure EVM smart contracts for identity, agreements, micropayments, and DeFi primitives.

  • Develop APIs and backend services to integrate smart contracts with off-chain components and support product functionalities.

  • Build user interfaces and dashboards for data visualization related to micropayment activity, indexers, delegation, and liquidation status.

Job description

About Semiotic LabsSemiotic Labs builds advanced Web3 infrastructure, autonomous agents, and cryptoeconomic protocols that power decentralized finance and data economies. As a core developer team for The Graph, Semiotic Labs is pioneering trustless, efficient, and scalable financial primitives.
Our suite of products includes:
  • GraphTally a trust-minimized micropayment system for decentralized service providers.
  • Allocation Optimizer: an Agent for dynamic stake distribution across subgraphs in The Graph.
  • Dynamic Pricing Algorithm: Adaptive online query pricing for Indexers.
  • Holographic Homomorphic Signature Scheme (H2S2): Cryptographic primitive aggregating signatures for efficient verification.
  • State-Channel Micropayments (via GraphTally): Off-chain payments minimizing on-chain cost for low-value transfers.
  • AutoAgora: AI-powered tool for query pricing and negotiation in The Graph.
  • RL & Neural-Network Cost Prediction / zk-SNARK Enhancements AI-driven pricing, verifiable queries, and privacy-preserving proof mechanisms.

Role Overview
We're seeking a Smart Contract Engineer (EVM-focused) to work across Semiotic Labs' product suite. You will design and implement smart contracts, build scalable backend services, and develop data-driven dashboards. The work will touch on areas such as on-chain identity, agreements, micropayments, and DeFi logic, while integrating with advanced indexing and delegation mechanics within The Graph ecosystem.
As part of our team, you'll juggle with:
Smart Contracts
  • Design, implement, and deploy secure EVM smart contracts (Solidity).
  • Build logic for identity, on-chain agreements, micropayments, and DeFi primitives.
  • Conduct audits and optimizations for gas efficiency and security.

Backend Services
  • Develop APIs and services integrating smart contracts with off-chain components (Node.js, Go, Python).
  • Support products such as GraphTally and Allocation Optimizer with backend logic.
  • Implement scalable infrastructure for micropayments, pricing, and staking optimization.

Frontend / Dashboards
  • Build UIs for data visualization and interaction, including dashboards for:
  • Micropayment activity
  • Data providers and indexers (The Graph)
  • Delegation and staking optimization
  • Liquidation status tracking
  • Use React or similar frameworks to create intuitive, data-rich user interfaces.

Integration & Collaboration
  • Bridge contract logic with backend services and UI.
  • Work with cryptographers, AI researchers, and protocol engineers to integrate cutting-edge tools.
  • Contribute across Semiotic's full suite of products.

Quality & Deployment
  • Write tests (unit, integration, end-to-end) across contract, backend, and frontend layers.
  • Maintain CI/CD pipelines for EVM deployments across testnets and mainnet.
  • Follow best practices in Web3 security and code quality.

  • Strong experience designing and deploying Solidity contracts.
  • 3+ years backend development (Node.js, Go, or Python).
  • Experience with React or other frontend frameworks for dashboards.
  • Knowledge of EVM internals, gas optimization, and DeFi building blocks.
  • Understanding of staking, delegation, indexers, and liquidation mechanics.
  • Strong debugging, testing, and collaborative skills.

Nice-to-Have
  • Familiarity with on-chain reputation, identity frameworks, or agreement systems.
  • Contributions to open-source Web3 projects.
  • Understanding of cryptographic tools like H2S2, zk-SNARKs, or state-channel micropayments.
