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.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Aztec’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.


Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
