Before you read the details of this role, there’s something you should know. At Matter Labs, we don’t see ourselves as a company, but as a highly aligned global team on a single mission: to accelerate the mass adoption of crypto for personal sovereignty.  Our core technology – zkSync Era – is a layer 2 rollup that uses advanced cryptography called zero-knowledge proofs to scale Ethereum without compromising on security or decentralization. zkSync Era is EVM compatible, which means projects on Ethereum and other EVM-based blockchains can easily deploy on zkSync Era to take advantage of low gas fees and high transaction speeds. With a total of $458 million in mission-driven funding, zkSync Era is the first EVM-compatible ZK Rollup to go live on testnet (February 2022) and be deployed on mainnet (October 2022). As we enter the endgame for Ethereum scaling, we are committed to full open source and building in public toward our stated mission [so that even if we fail, the...
