At Matter Labs, we believe freedom drives progress and prosperity. We don’t see ourselves as a company, but as a team aligned around a single mission: to advance personal freedom for all (see   ZK Credo ). To achieve this goal, we’re building zkSync — a credibly neutral, fully open source technology stack and network on top of Ethereum, which is owned and governed by its community. We use advanced cryptography called   zero-knowledge proofs   to scale Ethereum infinitely without compromising on security or decentralization. With a world-class team, a community of over 1M supporters across   Twitter   +   Discord , and hundreds of millions $ in   funding , we have abundant resources to accomplish the mission. The Role We are looking for a Senior Protocol Engineer with strong knowledge of Ethereum and the EVM to join our Core Team. Your scope will include design and implementation for the zkSync smart contract platform: a zero-knowledge-proof-friendly...
