Position: Applied Cryptography Engineer
Company: Matter Labs
Experience required: 1y

At Matter Labs, we are building **ZK Sync**: technology for scalable smart contracts with privacy, secured by the latest generation of zero-knowledge proofs. 

The mission of ZK Sync is to scale public permissionless blockchains (such as Ethereum) to millions of users in a completely trustless manner -- relying on pure Math. Succinct zero-knowledge proofs are currently the only viable way to achieve this goal, and we are proud to be one of a few companies in the world with a strong expertise in this field.

This is an extremely ambitious and technologically challenging task with a lot of unknowns. However, if we succeed, in a few years it will have the same impact on the global trade and finance as Skype had on the telecom industry.

** The Role**

We are looking for talented cryptographers to join our core team. Your task scope will include design and implementation of the latest zero-knowledge proof systems (e.g. https://eprint.iacr.org/2019/1400.pdf).

We expect you to independently conduct research in your area of ownership, design, implement and document solutions.

**Your Profile**

- You are driven by passion, curiosity, and desire to make a meaningful contribution to the world.
- Strong background in math / information security.
- Proficiency in Rust, C++, Golang or similar languages. We are working primarily with Rust, but prior experience with this language is not mandatory.
- Experience implementing cryptographic protocols.
- Interest in Zero-Knowledge Proofs (SNARKs, STARKs, Bulletproofs, etc).
- Ownership mindset and a track record of successfully accomplished projects.

**The Offer**

We offer above-average compensation and equity options. You can work from one of nice our offices (Berlin/Kiev) or remotely.

We have a small focused team. No time tracking, minimum bureaucracy, only results matter. We’ll provide you with anything you need to learn, grow and be more productive.
