We are looking for an experienced Blockchain Engineer to contribute to a Web3 developer reputation platform currently under active development.
The platform creates verifiable developer profiles from on-chain activity, smart contract deployments, technical contributions, attestations, project history, and other professional evidence.
You will work on blockchain architecture, smart contracts, wallet interactions, on-chain data, protocol integrations, security, testing, and deployment. Depending on your background, your work may focus on EVM, Solana, Bitcoin, Cosmos, Move-based networks, zero-knowledge systems, or other blockchain ecosystems.
Responsibilities:
Design, develop, test, and maintain blockchain components and smart contracts.
Build secure wallet, signature, transaction, and authorization flows.
Integrate blockchain systems with backend services, indexers, APIs, and frontend applications.
Review existing architecture for security, reliability, scalability, and performance.
Work with on-chain data, contract events, attestations, credentials, and reputation logic.
Write tests, deployment tooling, and clear technical documentation.
We are interested in engineers with strong hands-on experience in blockchain development, whether your background is in Solidity/EVM, Rust/Solana, protocol engineering, blockchain infrastructure, smart contract security, ZK systems, cross-chain technology, or on-chain data.
You do not need experience across every blockchain ecosystem. Deep practical experience in one or more areas is more important than familiarity with a long list of tools.
