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.
