• Demonstrable experience developing and testing smart contracts.
• Strong proficiency in Solidity and familiarity with the Ethereum Virtual Machine.
• Experience with tools such as Foundry, Hardhat, or comparable smart contract development frameworks.
• Understanding of blockchain transactions, event logs, wallet interactions, and contract deployment.
• Knowledge of common smart contract vulnerabilities and secure development practices.
• Familiarity with Git, automated testing, CI/CD, and application programming interfaces.
• Strong attention to detail and professional proficiency in English.

Benefits

• Fully remote work arrangement, subject to employment eligibility.
• Opportunity to develop blockchain applications and smart contract infrastructure.
• Collaboration with experienced software and security professionals.
• Access to technical training and ongoing professional development.
• Flexible working practices and opportunities to contribute to evolving Web3 technologies.
