About Aztec

At Aztec we believe privacy isn’t just a fundamental right, but a creative force for web3. Our goal is to unleash the full potential of decentralized technologies by building an open, privacy-first network with no compromises.

Privacy enables use cases that otherwise would not be possible and accelerates mainstream adoption. The next wave of web3 applications will require programmable privacy. Aztec’s technology empowers developers with the tools to build private applications and bring their ideas to reality.

Our journey started while building an application to bring syndicated loans on chain. We realized that our idea was a nonstarter without privacy. There were no solutions to offer privacy on public blockchains - so we sought out to build it ourselves. Since then, we've made industry-leading advances in cryptography, and deployed a private money platform and a private DeFi platform.

To realize our vision of implementing privacy on a public blockchain, we are building a world-class team of cryptographers, engineers, and ecosystem builders. Supporting us on this journey are leading investors including Paradigm, Variant, Consensys, and a_capital.

Team and Responsibilities

We’re creating a general-purpose private smart contract layer for Ethereum, affectionately dubbed ‘Aztec 3’.

We utilise bleeding-edge cryptography in our tech stack to realise private transactions on a public blockchain network, particularly in the realm of zero-knowledge cryptography.

As a result we possess a world-class R&D team that has co-authored the Plonk and Plookup ZK-SNARK protocols. Plonk in particular is rapidly becoming an industry standard ZK-SNARK technology.

We are looking for experienced cryptographers to expand our R&D team and allow us to further enhance the state-of-the-art when it comes to generating proofs of private computation.

Role focus

Research techniques to improve both the constant and asymptotic performance of our cryptographic protocols

Perform literature reviews to identify new developments that could improve the Prover/Verifier efficiency of our cryptographic protocols (or replace them entirely)

Develop security proofs for our ZK-SNARK circuit architectures

Liaise with our applied cryptographers to assist them with implementing our cryptographic protocols in software

Required experience

PhD-level qualification in cryptography or a related field
Named author in one or more papers in the field of zero-knowledge cryptography
Familiarity with algorithms, data structures and basic programming concepts
Ability to read and understand software implementations of cryptographic protocols written in C++
A penchant for clear and comprehensive documentation
Able to provide clear and constructive feedback for more junior cryptographers / applied cryptographers, mentoring where necessary
A passion for blockchain, its potential, and what we’re trying to achieve.

This is the culture we hire for:

Self starters - We expect teammates to be adaptable to meet the needs of the organization and complete the tasks at hand.
Deep thinkers - We take the time to rigorously collect data and understand the consequences of different approaches before building the solution.
Passion learners - We are passionate about technology and love to learn and build.
Considerate teammates - We are mindful of how our work is interconnected and the importance of communication

What we offer:

A highly competitive compensation package (including equity)
Flexible and remote work environment
25 days holiday + bank holidays annually
An opportunity to work at the cutting edge of blockchain and FinTech with a world class cryptography and engineering team
