At Matter Labs, we believe freedom drives progress and prosperity. Our mission is to advance freedom for all — through mass adoption of crypto.To make that real, we’re building ZKsync, a verifiable blockchain network secured by zero‑knowledge proofs. Backed by over $250 million in funding from some of the world’s smartest investors , we move fast, ship often, and judge ourselves by the results we create.More than 20 teams already run or are building custom ZKsync chains on our network, from crypto leaders like Crypto.com, Abstract, and Lens, to global brands such as Deutsche Bank and Xsolla.
Business Area / Department Overview
The Protocol Engineering team at Matter Labs is responsible for the design, implementation, and evolution of the ZKsync protocol. This includes both L1 and L2 components, from core contracts and verification systems to the zkSync smart contract platform — a zero-knowledge-friendly virtual machine powering ZKsync Era.
Key Responsibilities of Role
Design and implement the ZKsync smart contract platform (zk-friendly VM).
Develop system contracts (Solidity, Yul) and server-side components for L1 and L2.
Conduct independent research, design, prototype, and document solutions.
Shape the protocol roadmap in collaboration with internal teams and external partners.
Contribute to cross-functional discussions, ensuring secure and scalable protocol evolution.
