The Blockchain Engineer will be responsible for the architecture and implementation of blockchain-based technologies for the[BAT roadmap](https://basicattentiontoken.org/bat-roadmap-1-0/). The primary task is the development of an open decentralized blockchain-based ads ecosystem, involving user contributions, attention rewards, and publisher contributions over several phases. The first phase will include transition of our existing Bitcoin based proof-of-concept, so familiarity with Bitcoin is a plus.
The ideal candidate will have previously worked with distributed applications, have extensive familiarity with Ethereum and related blockchain technologies including smart contracts (especially ERC-20 tokens), sidechains, and state channels. They must be well versed in the current best practices surrounding smart contract development and be able to rigorously test and verify contract code.
