At Matter Labs, we are building zkSync: a blockchain scaling solution secured purely by cutting-edge cryptography. Our mission is to scale Ethereum to billions of users, fully preserving its most valuable properties — permissionlessness, trustlessness, and resilience, — in order to protect and enhance global economic freedom.
We hold a strong opinion that zero-knowledge proofs (ZKP) are the only technology today that can achieve this goal. We are also proud to be the pioneer of the ZKP tech on Ethereum, and one of the few companies in the world with strong expertise in this field. Our contributions over the last 3 years include the first ZK rollup ever built, the first implementation of recursive ZK proofs on Ethereum, and the world’s first practical FPGA-based ZKP accelerator. Most recently, we launched a zkEVM testnet, making zkSync the first ZK rollup capable of executing native Ethereum smart contracts.
Across all hires we make at Matter Labs, regardless of role or team, we look for signals that a candidate will thrive in a culture like ours, where we value freedom, ownership mindset, and meritocracy.
This role’s main responsibility is for the secure implementation of our smart contracts.
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.
You will work on a deeply mission-driven project, making a significant contribution to the greater economic and political freedom globally. All of our code is open source.
We are a fast-growing startup in the world’s fastest-growing industry. We offer highly competitive cash and equity compensation.
We respect every team member as an individual. We encourage a healthy work/life balance without excessive overtime. We will provide you with anything we can to help you grow professionally, and be productive and happy.
We are a remote-first, results-only organization. Most of the team is based in Europe, and we currently only consider candidates located between EST (UTC-5) and ICT (UTC+7). You are expected to adjust your schedule, work and communication methods to such an environment.
zkSync is a ZK rollup, a Layer-2 scaling solution that preserves the security properties of the underlying blockchain by leveraging the latest generation of succinct zero-knowledge proofs.
Matter Labs is the pioneer of zero-knowledge proof tech on Ethereum. The company has launched the first-ever public ZK rollup prototype in early 2019, was the first to implement recursive ZK proofs on Ethereum, and created the world’s first practical FPGA-based hardware for ZKP acceleration in 2020. Matter Labs recently launched a zkEVM testnet, making zkSync the first ZK rollup capable of executing native Ethereum smart contracts.
Matter Labs’ team is rooted in the belief that cryptography and blockchain are essential technologies for protecting and fostering freedom globally. They enable mutually distrusting counterparts to collaborate without relying on authorities or third parties. Blockchains enabled by zero-knowledge proofs promise a fairer and more efficient global digital economy.
