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.

Role focus:

A key goal of Aztec over the coming year is to meaningfully decentralize the network. Achieving this will require a multi-disciplinary approach that will cover our entire tech stack. One area of particular attention is the networking layer. We’re looking for engineers with specific network protocol experience to:

  • Focus on development of Aztec’s networking layer.
  • Decentralise the transaction pool, by implementing a p2p network protocol.
  • Ensure rapid propagation of transactions through the network.
  • Play a critical role in designing and building a scalable and resilient p2p network cable of processing a large proportion of the worlds financial transactions (Rival visa / mastercard but p2p)
  • Contribute back to a thriving open source eco-system
  • Hook directly into L1 devp2p protocol for advanced L2 synching.


  • Bachelor’s degree in related technical field
  • 6+ years industry engineering experience
  • Fluent in Typescript (3+ years experience)
  • Solid understanding of internet networking protocols.
  • Basic understanding of at least one p2p protocol.
  • Experience writing networking code in a production environment.
  • Development experience with Ethereum.
  • Excellent communication skills.

Nice-to-have experience:

  • Located in the UK or can operate in Greenwich Mean Time Zone
  • Familiarity with current Ethereum tooling (for inspiration)
  • Passion for the web3 space
  • Familiarity with other private blockchain technologies like ZCash
  • Knowledge of peer-to-peer decentralized networking tools
  • A love for Merkle Trees

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
