Senior Protocol Engineer

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.

The Role

We are looking for a Senior Protocol Engineer to join our Core Team. Your scope will include design and implementation for the zkSync smart contract platform: a zero-knowledge-proof-friendly virtual machine. This team is responsible for the evolution of our protocol and works at both L1 (including our core contracts, verification contracts, and bridge) and at L2, helping shape the direction of zkSync 2.0.

What You'll Be Doing

    • Joining the team responsible for the design and implementation of the zkSync smart contract platform: a zero-knowledge-proof-friendly virtual machine
    • Developing at L1 and L2, including system contracts (implemented in Solidity) and server side changes
    • Shaping the future of the protocol through research, design, prototyping, engineering, and discussion with external partners
    • Conducting independent research in your area of ownership, design, implement and document solutions, and potentially leading a team

What We Look For in You

    • Excellent understanding of Ethereum and the EVM
    • Experience with Solidity or Vyper
    • 5+ years in software development
    • Driven by passion, curiosity, and desire to make a meaningful contribution to the world
    • Fluency in Rust, C++, Scala, Java or Go - we work primarily with Rust, but prior experience with this language is not mandatory
    • Deep understanding of software engineering best-practices
    • Ownership mindset and a track record of successfully accomplishing projects
    • In-depth knowledge of common algorithms, data structures, and their computational & memory complexities
    • Experience implementing data structures and algorithms from scratch
    • Experience in cryptography/high-load/protocols design is a big plus
    • Fluent written and spoken English
Working at Matter Labs

You will receive highly competitive compensation and stock options. The roles are fully remote, but you are welcome to work from one of our offices, or a co-working space of your choice.
