Senior Front-End Engineer

Senior Frontend Engineer About Inco Inco is building the confidentiality layer for blockchains through encryption technologies. We’re building the next generation of secure, scalable, and privacy-enhancing solutions for Web3, enabling fintech, payments, and blockchain applications to have the same confidentiality and capabilities users expect from Web2. Who You Are We’re looking for a senior frontend engineer who has built production-grade Web3 user experiences and understands the unique complexity of blockchain applications. You have strong frontend fundamentals, but you also understand that Web3 frontend engineering is not just about building interfaces. It requires safely fetching and interpreting onchain data, integrating wallets, handling signatures, managing client-side state, and designing user flows where security and correctness matter. You should be comfortable building polished, reliable UIs while also thinking deeply about how users interact with wallets, sign messages, grant permissions, manage session keys, and execute intent-based flows. You understand the security risks of asking users to sign transactions or messages, and you care about making those flows clear, safe, and difficult to misuse. We’re looking for someone senior who can own frontend architecture end-to-end, raise engineering standards, and mentor more junior engineers. You should be the type of person who can turn ambiguous product requirements into secure, elegant, production-ready user experien
