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.

Team and Responsibilities

We’re creating a general-purpose private smart contract layer for Ethereum, affectionately dubbed ‘Aztec 3’.

We utilize bleeding-edge cryptography in our tech stack to realize private transactions on a public blockchain network, particularly in the realm of zero-knowledge cryptography.

As a result we possess a world-class R&D team that has co-authored the Plonk and Plookup ZK-SNARK protocols. Plonk in particular is rapidly becoming an industry standard ZK-SNARK technology.

We are looking for experienced cryptographers to expand our R&D team and allow us to further enhance the state-of-the-art when it comes to generating proofs of private computation.

Role focus:

  • Research techniques to improve both the constant and asymptotic performance of our cryptographic protocols
  • Perform literature reviews to identify new developments that could improve the Prover/Verifier efficiency of our cryptographic protocols (or replace them entirely)
  • Develop security proofs for our ZK-SNARK circuit architectures
  • Liaise with our applied cryptographers to assist them with implementing our cryptographic protocols in software

Required Experience:

  • PhD-level qualification in cryptography or a related field
  • Named author in one or more papers in the field of zero-knowledge cryptography
  • Familiarity with algorithms, data structures and basic programming concepts
  • Ability to read and understand software implementations of cryptographic protocols written in C++
  • A penchant for clear and comprehensive documentation
  • Able to provide clear and constructive feedback for more junior cryptographers / applied cryptographers, mentoring where necessary
  • A passion for blockchain, its potential, and what we’re trying to achieve.

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

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

Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past. For more information about this form or the equal employment obligations of federal contractors under Section 503 of the Rehabilitation Act, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.

How do you know if you have a disability?

You are considered to have a disability if you have a physical or mental impairment or medical condition that substantially limits a major life activity, or if you have a history or record of such an impairment or medical condition.

Disabilities include, but are not limited to:

  • Autism
  • Autoimmune disorder, for example, lupus, fibromyalgia, rheumatoid arthritis, or HIV/AIDS
  • Blind or low vision
  • Cancer
  • Cardiovascular or heart disease
  • Celiac disease
  • Cerebral palsy

  • Nervous system condition for example, migraine headaches, Parkinson’s disease, or Multiple sclerosis (MS)
  • Psychiatric condition, for example, bipolar disorder, schizophrenia, PTSD, or major depression

PUBLIC BURDEN STATEMENT: According to the Paperwork Reduction Act of 1995 no persons are required to respond to a collection of information unless such collection displays a valid OMB control number. This survey should take about 5 minutes to complete.
