Job Description

About Matter Labs 

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 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 testnet, making zkSync the first ZK rollup capable of executing native Ethereum smart contracts.

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

You will build a cross-functional security team and take the overall responsibility for security of the zkSync ecosystem, including:

  • Security of the zkSync protocol:
    • Cryptographic primitives.
    • Zero-knowledge proof circuits.
    • Solidity smart contracts.
    • The build supply chain.
  • Security of our smart contract development environment:
    • Security of the compiler.
    • Security of the developer tooling.
  • OpSec/InfoSec of the cloud and blockchain infrastructure of Matter Labs.

Expectations 

Security Policy: You will set the high bar of security standards and instill a strong security mindset and awareness throughout the entire team.

Execution: We expect you to design and implement security best practices at every stage of our development process. You will work closely with engineering and other functions to ensure secure operation and development of highly secure products. You will also work with external security team and coordinate security audits, formal verification procedures, and other measures 

Team Leadership: You will hire, train, motivate, and mentor and security professionals, clearly defining individual roles and responsibilities.

Remote work: We are a remote-first, results-only organization. Most of the team is based in Europe, and we currently only consider candidates located between EST (UTC-5) and ICT (UTC+7). You are expected to adjust your schedule, managing style, work and communication methods to such an environment.

Your Competencies

  • Experience in a similar position.
  • Experience in security of cryptographic protocols.
  • Understanding the specifics of smart contract security (ideally related to EVM).
  • Excellent oral and written communication in English.

The Offer

You will work on a deeply mission-driven project, making a significant contribution to the greater economic and political freedom globally. All of our code is free open source.

We are a fast growing startup in the world’s fastest growing industry. We offer highly competitive cash and equity compensation.

We respect every team member as an individual. We encourage healthy work/life balance without excessive overtime. We will provide you with anything we can to help you grow professionally, be productive and happy.
