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 highly motivated person who will help to secure our Layer 2 scaling protocol. You will be working closely with our Engineers starting with early stage of the feature design through the development life cycle and till the production deployment ensuring the highest security standards are applied at each step. A substantial part of the job is to play with our code “in the wild” to test the implementation in exceptional cases.

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
Mentor others on the team about security and share your knowledge.

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
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
Fluent written and spoken English
