Job Description

At Matter Labs, we are building zkSync: a blockchain scaling solution secured purely by cutting-edge cryptography. Our mission is to scale Ethereum to billions of users, fully preserving its most valuable properties — permissionlessness, trustlessness, and resilience, — in order to protect and enhance global economic freedom.

We hold a strong opinion that zero-knowledge proofs (ZKP) are the only technology today that can achieve this goal.

We are also proud to be the pioneer of the ZKP tech on Ethereum, and one of the few companies in the world with strong expertise in this field. Our contributions over the last 3 years include the first ZK rollup ever built, the first implementation of recursive ZK proofs on Ethereum, and the world’s first practical FPGA-based ZKP accelerator. Most recently, we launched a zkEVM mainnet, making zkSync the first ZK rollup capable of executing native Ethereum smart contracts. For the latest updates check out our Twitter.

Across all hires we make at Matter Labs, regardless of role or team, we look for signals that a candidate will thrive in a culture like ours, where we value freedom, ownership mindset, and meritocracy.

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.

We expect you to independently conduct research in your area of ownership, design, implement and document solutions, and potentially lead a team. 

What You'll Be Doing

  • Join the team responsible for the design and implementation of the zkSync smart contract platform: a zero-knowledge-proof-friendly virtual machine
  • Responsibilities will include development at L1 and L2, including system contracts (implemented in Solidity) and server side changes.
  • Help shape the future of the protocol through research, design, prototyping, engineering, and discussion with external partners.
  • We expect you to independently conduct research in your area of ownership, design, implement and document solutions, and potentially lead a team

What We Look For in You

  • An 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 are working 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 accomplished 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 will be a big advantage
  • English is your native language or you are completely fluent
Working at Matter Labs

You will receive highly competitive compensation and equity options. The roles are fully remote, but you are welcome to sit in one of our offices, or a co-working space of your choice. We operate in small, focused teams, with no time tracking and minimum bureaucracy. Only results matter. We will provide you with anything you need to learn, grow, and be more productive.

Working at Matter Labs it’s critically important that our goals and values (freedom, ownership mindset, and meritocracy) align. Building a potentially globally transformative product, we value diversity of thought, and believe that diversity of thought comes from diversity of backgrounds. We welcome applicants from across the spectrum of all: race, gender, ethnicity, culture, sexual orientation, age, religion, spirituality, identity and experience.
