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 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 Yul) 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
