Who we are

Aztec Network releases its next iteration of zk.money, demonstrating the power of the Aztec Connect SDK to build seamless integrations with DeFi protocols like Lido and Element. At Aztec we believe decentralization is premised on individual rights. Without widely accessible privacy, we compromise our ability to choose how we live our lives and earn our livelihoods. Aztec is built from the ground up to be privacy-first. Our UTXO architecture, inspired by Bitcoin, allows for end-to-end encrypted transactions. And our category-defining zero-knowledge research means privacy is fast and efficient.

YOUR CHALLENGES:

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.

GET ONBOARD IF:

  • Knowledge of algorithms, data structures, systems level programming, etc
  • 3+ years solid engineering experience
  • Automated testing of all mission-critical code
  • A high degree of focus on code quality and reducing complexity
  • Full stack capable, but with a focus on backend architecture, development and deployment at scale
  • Knowledge of JavaScript and/or TypeScript
  • A penchant for clear and comprehensive documentation
  • Confidence to probe and suggest improvements to the existing architecture and codebase
  • Able to provide clear and constructive feedback on less senior engineers’ PR’s, mentoring where necessary
  • A passion for blockchain, its potential, and what we’re trying to achieve

‍

It's great if you are:

  • Familiarity with current Ethereum tooling (for inspiration)
  • An understanding of the finer details of the Ethereum Virtual Machine (again, for inspiration)
  • An understanding of other Layer 2 solutions and their tooling
  • Familiarity with other private blockchain technologies like ZCash
  • Knowledge of peer-to-peer decentralised networking tools
  • An understanding of arithmetic circuits and their unusual limitations
  • A love for Merkle Trees


‍

WHY US:

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