About the Role

We are looking for a highly skilled Senior Smart Contract Developer with a strong background in Solidity, TypeScript, and backend engineering. The ideal candidate will be responsible for designing, building, auditing, and maintaining on-chain logic while also contributing to off-chain services, APIs, and database integrations. This position requires strong communication skills in English, attention to detail, and a passion for debugging and problem solving.

Responsibilities

  • Architect, develop, and maintain smart contracts primarily using Solidity

  • Design and implement secure and gas-efficient on-chain logic aligned with business and protocol requirements

  • Integrate blockchain components with backend services written primarily in TypeScript

  • Build, document, and maintain REST and/or GraphQL APIs

  • Work with databases (SQL/NoSQL), modeling data and ensuring performance and reliability

  • Participate in technical planning, code reviews, audits, and security assessments

  • Own debugging and testing end-to-end — on-chain, off-chain, tooling and integrations

  • Collaborate closely with founders, engineers, auditors, and product stakeholders

  • Maintain accurate and clear English-based technical documentation and communication

  • Research and propose improvements, best practices, and new capabilities across the stack

Requirements

  • 5+ years of professional software engineering experience

  • 3+ years of Solidity development experience

  • Strong knowledge of Ethereum ecosystem, ERC standards, wallets, gas optimization, and on-chain patterns

  • Proficiency with TypeScript, Node.js and modern backend architectures

  • Experience building and consuming APIs (REST, WebSockets, GraphQL)

  • Solid understanding of data modeling and databases (PostgreSQL, MySQL, MongoDB, Redis or similar)

  • Strong testing mindset (Hardhat, Foundry, Jest or similar)

  • Excellent debugging skills and passion for deep problem investigation

  • Fluent or near-native English communication skills, written and spoken

  • Ability to work independently with strong accountability and ownership

  • Familiarity with security considerations: reentrancy, flash loans, oracle risks, underflows/overflows, access control, upgradeability, etc.

Nice to Have

  • Experience with auditing smart contracts

  • Familiarity with Layer 2 and cross-chain patterns

  • DevOps familiarity (Docker, CI/CD pipelines, infrastructure as code)
