Senior Security Engineer (Blockchain)

Before you read the details of this role, there’s something you should know. At Matter Labs, we don’t see ourselves as a company, but as a highly aligned global team on a single mission: to accelerate the mass adoption of crypto for personal sovereignty. 

Our core technology – zkSync – is a layer 2 rollup that uses advanced cryptography called zero-knowledge proofs to scale Ethereum without compromising on security or decentralization. zkSync is EVM compatible, which means projects on Ethereum and other EVM-based blockchains can easily deploy on zkSync to take advantage of low gas fees and high transaction speeds.

With a total of $458 million in mission-driven funding, zkSync is the first EVM-compatible ZK Rollup to go live on testnet (February 2022) and be deployed on mainnet (October 2022). As we enter the endgame for Ethereum scaling, we are committed to full open source and building in public toward our stated mission [so that even if we fail, the community and the ecosystem will benefit from our contribution].

The Role

We are looking for an experienced and highly motivated person who will take full ownership of the secure implementation verification. This includes deep familiarity with our cryptographic primitives and protocols, as well as an understanding of the particularities of Rust. You are expected to be up-to-date with published work and vulnerability reports. A substantial part of the job is to play with our code “in the wild” to test the implementation in exceptional cases, and to work with our Engineers on our test coverage.

What You'll Be Doing

    • Improve the security of our smart contracts through audits, testing, formal verification, etc
    • Set and maintain good security and engineering processes
    • Teach and mentor others on the team about security

What We Look For in You

    • Driven by passion, curiosity, and desire to make a meaningful contribution to the world
    • Have strong security fundamentals knowledge
    • Have experience in securing smart contracts threat analysis, hacking, penetration testing, intrusion detection, logging, malware analysis, or forensics
    • Fluency in Rust, C++, Golang, or similar languages - we work primarily with Rust, but prior experience with this language is not mandatory
    • Have deep knowledge and passion for crypto applications and Ethereum 
    • 3+ years of working experience in a related cybersecurity role
    • Experience with discovering vulnerabilities at the design/system level
    • Proven ability to communicate across roles to drive a security mindset across the company
    • Understanding Solidity and smart contract best-practices is a plus
    • Experience with developing security plans, processes, and controls is preferable
    • Full ownership of your area of responsibility, including research and implementation
    • Fluent written and spoken English
