Applied Cryptography Engineer (Zero-Knowledge Proofs) (offline)

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 (SNARKs, STARKs, Bulletproofs, etc).

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](https://eprint.iacr.org/2019/458.pdf) to building a full ZK proof system like [RedShift](https://eprint.iacr.org/2019/1400.pdf).

Your Profile

- 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).
- Proficiency in Rust, C++, Golang or Python. We are working primarily with Rust, but prior experience with this language is not mandatory.
- Ownership- and results-driven mindset.
- Excellent English.

We expect you to independently conduct research in your area of ownership. Please only apply if you feel capable to implement protocols similar to the ones mentioned above on your own from analyzing the scientific papers.

About Matter Labs

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.
