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.
We're creating a general-purpose private smart contract layer for Ethereum, affectionately dubbed ‘Aztec 3’.
We’re now looking for a full-stack engineer to help build out Aztec 3. Think of the best software and tooling in the Ethereum ecosystem today. The successful candidate will help build private equivalents of it all! That is, software which allows: developers to build and deploy private smart contracts; users to privately interact with them; and rollup providers to keep the network running smoothly.
- Building a ‘full node’, in TypeScript, which:
- Rolls-up private smart contract transactions, making use of our recursive zk-SNARK cryptography library;
- Reliably syncs with the Aztec Network’s L1 & L2 states;
- Allows private and secure execution of users’ smart contract transactions;
- Manages sensitive user data securely;
- Interfaces neatly with developers’ apps;
- Allows p2p relaying of transactions across the network;
- Has a ‘test’ mode, which enables testing of complex private smart contract interactions.
- Building a TypeScript ‘wrapper’ module that allows developers to easily build apps which can interface with the above full node and with our custom Noir language’s suite of tools.
- Building complex example applications to test and demonstrate Aztec 3’s capabilities.
- Liaise with the cryptography team, to ensure our cryptography library exposes everything the full node will need.
- Liaise with our Noir language team, to ensure our custom private smart contract programming language provides an intuitive experience for our target audience of developers.
- Liaise with our business team, to ensure Aztec 3 delivers what the ecosystem needs.
- Knowledge of algorithms, data structures, systems level programming, etc
- 3+ years solid engineering experience
