Security Engineer (Blockchain)

At Matter Labs, we are building zkSync: a zero-knowledge rollup (ZK-rollup) Ethereum Layer 2 scaling solution. Our mission is to accelerate the mass adoption of crypto for personal sovereignty. zkSync’s core technology – an EVM-compatible ZK-rollup – is designed to scale Ethereum without degrading its decentralization or security. 

Across all hires at Matter Labs we look for signals that a candidate will thrive in a culture like ours – where we value freedom, an ownership mindset, and excellence. 

We’ve raised a total of $458 million to help us achieve this mission from investors such as Blockchain Capital, Dragonfly Capital, LightSpeed Venture Partners, Variant, Andreessen Horowitz (“a16z”), and many more. This includes $200 million dedicated to an ecosystem fund coming from BitDAO.

We’re driven by our mission and guided by our values, the most fundamental of which is freedom. That’s why we’ve decided to release zkSync 2.0 under MIT Open Source at the Fair Onboarding Alpha milestone. Open-sourcing zkSync 2.0 will give the ecosystem the freedom to view, to modify, and to fork the code. This will be the first time a general-purpose ZK-rollup is fully open-sourced.
