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 talented cryptographers or developers with strong math background to join our core team. Your task scope will include design and implementation of the latest zero-knowledge proof systems and cryptographic protocols (mainly FRI-based systems or modern sum-check based), as well as exploration of efficient application of existing ideas for implementation of the particular proven statements. This role will move towards a leadership position with direct reports in the cryptography team.
You will have a chance to attend major cryptography conferences and work with the world's top scientists in the field.
Task complexity ranges from implementing Poseidon hash function to building a full ZK proof system like RedShift and helping GPU and prover network engineers to integrated it.
What You'll Be Doing
Implement ZK provers and circuits for them.
Research and propose optimizations for provers and circuits.
Become very familiar with problems of physical hardware and large-scale prover deployments.
Help to supervise a small team of talented engineers and researchers.
Lead an effort to implement and deploy your ideas end to end.
What We Look For in You
Strong background in math / cryptography / information security (although most people in our crypto team hold a PhD in cryptography or physics, we do not strictly require a formal academic degree) – we want to work and push the cutting-edge technology.
Proficiency in Rust. We are working primarily with Rust, and an ability to write the code to express ideas is mandatory – many ideas require empirical testing, and it should not take a lot of your precious time.
Ownership- and results-driven mindset – we want all those new developments and achievements to be used and deployed for real-case uses, that also requires cooperation with other team and desire to see the final results of own work.
