Infrastructure Security Engineer

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 

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 and Discord, and hundreds of millions of dollars in funding, we have the resources to achieve our mission.

Join Matter Labs as a Senior Security Engineer (Infrastructure) and play a critical role in securing the infrastructure that powers zkSync. You’ll work across cloud, application, and systems layers to build and maintain robust defenses. Partnering closely with DevOps, engineering, and protocol security to embed security into everything we ship.

This role is ideal for someone who thrives in high-impact environments, enjoys solving complex technical challenges, and is motivated by the mission of protecting open-source and decentralized infrastructure.
