A Blockchain Engineer designs, develops, and maintains blockchain platforms and decentralized applications (dApps). The role involves implementing smart contracts, improving transaction throughput and scalability, securing consensus mechanisms, and integrating blockchain systems with external applications. Depending on the company, the engineer may work on public chains like Ethereum or private enterprise blockchains such as Hyperledger. Performance, cryptography, and security are major concerns because bugs in smart contracts or consensus logic can have irreversible consequences.
