About Aztec

At Aztec, our goal is to take the original promise of Ethereum–a decentralized and verifiable world computer–and expand its capability immensely by making it fully encrypted.

In the current public blockchain paradigm, users and entities unknowingly broadcast data in the public, compromising privacy and security to get trustlessness.

Not only are unencrypted blockchains inherently privacy-exposing, they require significant redundancy to compute and verify the legitimacy of transactions.

Implementing scalable encryption in a public blockchain paradigm requires cutting-edge math and engineering. Thankfully, our team of scientists and engineers invented Plonk, the industry-standard zkSNARK, and Noir, the universal language of zero knowledge.

Now, we’re building a first of its kind public-private encrypted blockchain: Ethereum, encrypted. And it’s now time to bring it to market.

We’ve raised $125 million from industry-leading investors including a16z crypto, Paradigm, Variant, Consensys, and a_capital, and we’re growing quickly.

The Role:

  • You have strong empathy and understanding of where pain points are during the development process
  • You have a strong desire to do things much better in comparison to other technologies and programming languages
  • You strongly understand typical developer workflow and have an idea of how Noir Language fits into it
  • You will develop solutions to help others get their job done in the most optimized way
  • You will work on libraries that will be used by other developers
  • You will work on Command Line Interface (CLI) applications 
  • You will develop User Interfaces for Integrated Development Environments (IDEs)
  • You will work on Delivery Processes (CI) to deliver software in an optimized and secure way
