About Us
At Aztec, our goal is to add privacy to Ethereum.
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 Layer 2 with private smart contracts. This requires new cryptographic primitives, a zero-knowledge DSL for writing contracts, a privacy-friendly execution environment, a carefully designed set of circuits that prove the validity of the chain to L1, a decentralized block-building and proving mechanism, and a top-tier user and developer experience. 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.
About the Role
We are looking for an applied cryptographer or a cybersecurity professional with love for applied cryptography, and with experience in auditing and breaking cryptographic protocols to join our security team.
Responsibilities
The goal of the team is to secure a large codebase including:
- proving system backend library [Barretenberg]
- Zero Knowledge Proofs DSL [Noir]
- our [node software]
- our [Private Execution Environment] and much more
You will need to find potential security issues, write novel tooling and apply existing mechanisms to detect bugs, assist internal software teams and external contractors with audits.
Qualifications
- Security experience in a software eng context (≥ 3 years)
- Industry (or large-project academic) programming experience in a low-level language (e.g., Rust or C++)
- Familiarity with applied cryptography and discrete mathematics (fields, elliptic curves)
- Excellent written and verbal communication skills on technical topics
- Participation in CTFs in a cryptography role a plus
- Compiler development experience a huge plus
- Web Security experience a huge plus
