Are you the one?
We are looking for an experienced and motivated Senior Blockchain Engineer to design and build secure, high-performance blockchain solutions for institutional and enterprise clients.
You will design and implement blockchain-based systems across the web3 ecosystem: from protocol-level components and smart contracts to Institutional DeFi and enterprise-grade financial applications.
This remote-first role involves deep collaboration with internal engineering and research teams, as well as external partners such as financial institutions, infrastructure providers, and blockchain foundations.
You should bring strong proficiency in one or more general-purpose programming languages and hands-on experience developing smart contracts in Solidity. A deep understanding of Ethereum’s architecture, solid engineering fundamentals, and a disciplined approach to problem-solving are essential.
The ideal candidate communicates clearly, writes maintainable code, and thrives in complex, multi-stakeholder environments. Knowledge of non-EVM chains, zero-knowledge proofs, and institutional DeFi protocols is highly valued.
Responsibilities include, but are not limited to:
At Nethermind, we celebrate diversity and are committed to creating an inclusive environment for all team members. We believe a variety of perspectives drives innovation and leads to better solutions for the blockchain community.
