Senior Software Engineer (Rust)

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 Software Engineer to join our Core Team. Your task scope will include design and implementation of the zkSync smart contract platform: zero-knowledge-proof-friendly virtual machine, protocol full node optimized for high-load, p2p network, consensus, etc. This role is full-time with a strong preference for candidates located in the EU. We are not currently hiring in the US.

What You'll Be Doing

• Design and implementation of the zkSync smart contract platform: zero-knowledge-proof-friendly virtual machine
• Protocol full node optimized for high-load, p2p network, consensus, etc.
• Conduct independent research in your area of ownership, design, implement, and document solutions, and potentially lead a team.

What We Look For in You

• 5+ years in back-end 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
• Some functional programming experience or or exposure with languages like Haskell
• Comprehensive knowledge of the tradeoffs made between different data storage systems i.e. Postgres, mySQL, mongoDB
• 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 and 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
