About the job

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

At the current stage of development, zkSync uses the default Solidity compiler, which is coupled with the EVM architecture too tightly. It imposes a lot of overhead along the compilation pipeline on the way to the zkSync virtual machine bytecode. We have to develop our own extension of the Solidity language, where all the zkSync-specific features can be added with ease. Apart from that, there is a lot of optimization space within the Yul generator and other parts of the compilation pipeline. We expect you to independently conduct research in your area of ownership, design, implement and document solutions.

What You'll Be Doing

• Developing of Solidity language extensions for zkSync
• Maintaining and handling the Solidity updates
• Optimizing and tweaking the solc's Yul generator
• Researching the possibilities for improving the compilation pipeline

What We Look For In You

• Driven by passion, curiosity, and desire to make a meaningful contribution to the world
• Fluency in C++, 3+ years of experience
• Experience with the Solidity/Yul compiler and general сompiler front-end development
• Deep understanding of software engineering best-practices
• Ownership mindset and a track record of successfully accomplished projects
• Fluent written and spoken English
• Knowledge of common algorithms, data structures, and their computational and memory complexities is critical, as well as experience in implementing them from scratch

Working at Matter Labs

At Matter Labs, you have the freedom to work how you want, when you want, and from where you want. 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 productive.

Our results-only environment means anyone who believes in our mission can join us, regardless of background, sexual orientation, race, gender, and age. Both our team and community are made up of people from different countries, cultures, ethnical and religious backgrounds. That's why, out of politeness and respect, we refrain from opinions on politics, religion, or sex at the workplace.

We designed our culture of freedom and ownership to persist as we scale and to establish the base for a positive-sum community as we move toward full decentralization.
