About Aztec

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.

Role focus:

We're looking for entrepreneurial thinkers that are interested in tackling new problems working across the entire codebase to:

Understand the full system architecture end to end
Prioritize and document technical debt and unnecessary complexity within the system
Implement solutions and improvements for key stakeholders
Refactor code, improving readability, documentation, maintainability and unit testing
Influence and enhance current engineering bar
Ensure we're using the most up-to-date tooling and development workflows for maximum developer efficiency

In particular, some of the tasks you could be working on include:

Improving the developer experience of writing Noir through extending its LSP (among other tools).
Improving the testing framework for Noir programs and performing exploratory work on testing smart contracts written in Noir.
Implementing new language features
Extending the Javascript tooling for working with Noir and identifying bottlenecks for proving in the browser.
Implementing optimized cryptographic primitives in Noir

Qualifications:

Bachelor's degree in related technical field
3+ years solid engineering experience (ideally in a web3/blockchain setting)
Fluent in Rust/Typescript (3+ years experience)
Previous compiler experience (very desirable but not required)
Able to provide clear and constructive feedback on less senior engineers’ PR’s, mentoring where necessary

Nice-to-have experience:

Located in the UK or can operate in Greenwich Mean Time Zone
Familiarity with other ZK languages and associated tooling (for inspiration)
Familiarity with current Ethereum tooling (for inspiration)
Passion for the web3 space
C++ experience

What we offer:

Flexible and remote work environment
25 days holiday + bank holidays annually
Additional benefits include health insurance, retirement plans, and opportunities for professional development.
Quarterly offsite travel for collaboration
Events and conference budget
An opportunity to work at the cutting edge of blockchain and FinTech with a world class cryptography and engineering team

Aztec Labs is an equal opportunity employer and we value creativity, diversity, and intellectual curiosity. If you're passionate about leveraging your creative talents to make a real-world impact, and if you want to be part of a team that's shaping the future of digital privacy, then we would love to hear from you.
