Blockchain Engineer Jobs in Web3

Common is building user-owned communication. We are creating open spaces for coordination, where decisions are done transparently and anyone can participate in improving their organization, starting in crypto.
Our initial product is widely used— a tool for community discussion and voting for web3 projects and DAOs, used by over 1000 communities collectively worth over $50b. Projects include Solana, NEAR, Polygon, Element Finance, dYdX, Osmosis, and many, many more. Over the long term, we want to support free forms of expression, whether expressed as chat messages, formal votes, or voting by “dollars”.
We work on a multi-disciplinary project bringing together ideals, cutting-edge technology, and making it easy for anyone to use. If this at all sounds interesting, please join us.
