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. 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

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. 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.

Experience

• 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

• 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.

Include Security

Right now we're looking for full-time application hacking experts, and we do mean experts. Experience in finding awesome vulns during web app pentests/code reviews is a must, but we also end up doing a fair number of mobile apps, client apps, server apps, APIs, and embedded devices/IoT as well. If your well-researched advisories or bug bounties show up around the web that's a really good sign. That being said, public advisories/bounties are not a requirement, we know there are plenty of good folks in the world who prefer not to publish any of their findings and we'd love to talk to all of you folks as well. We also do a bit of Reversing every now and then, so that experience helps for the occasion it arises.

We work on hundreds of projects a year, here's a current snapshot of what we've got going:

• We're hacking Java/Scala/C/C++/JS/Python mostly this month
• Next month an app with microservices written in 10 different programming languages, a windows userland sandbox, lots of mobile apps, and web services written in PHP/Java/Ruby.
• Rest of the year -- anything you can think of! It's never the same thing twice here.

Who you might be:

• You are an experienced application hacker. Web hacking is second nature, but perhaps so are other types of hacks (Reversing, Mobile, Client/Server, Crypto, Kernels, etc.)
• You've already done consulting, enterprise assessment work, or are always at the top of the bug bounties/CTFs for a number of years (sorry we don't hire Junior consultants, it is our company policy.)
• You're looking for a no BS environment where the process is optimized for getting out of your way and letting you find vulns. And you're happy to share and collaborate with the rest of the team.
• You love the flexibility of a remote work environment. Our team is based in NYC, but we have consultants across seven countries in North America, EU, and South America.
• You want to work with a low overhead team with no micro management, but also get to work with some heavy hitting big name clients (hundreds of clients served at this point) You want to work on assessments of the best and brightest tech companies of Silicon Valley, SF, and the world. Cutting edge technologies and massive scale systems, these are the types of engagements you dig and look for.
• You know work is important but plenty of time off and paid research time matters too. Depending on your past research experience you might end up doing four to eight weeks of non-billable research yearly. All consultants get four weeks paid time-off every year, national holidays, and the last week of every calendar year off.

Who we are:

We're an all expert boutique consulting company who have served hundreds of clients since our founding in 2010. We do this with a relaxed remote working environment where we can expertly hack on big name clients such as large websites, software companies, hardware companies, as well as tons of start-ups you've heard of. We do our best to put a different spin on the InfoSec/AppSec consulting game as we put our consultants and clients first and foremost! That means work on your own schedule, work from almost anywhere (we've had people finish RCE findings while camping in the French Alps), and we only work with self-directed and responsible senior consultants who consistently show professional results (pay is based on that kind of experience.)

You're right up our ally if you're currently doing security app assessments at another consulting shop and want a better work/life balance, with less client interaction (management handles that), skip all the BS parts of reporting, no sales/marketing/PMs that don't know what they're doing and cause you grief, no multiple layers of management, no bureaucracy, no "I just broke the Internet and I'm better than you" egos/attitudes, and more time to hack on stuff during engagements or do whatever you want to do in your down time (yes paid research time is included for our full-time team.)

If any of this sounds interesting please hit us up with a resume||CV and links to any of your work that might be public or a description of any private research you feel like sharing.

Pay/Benefits: We pay in the ballpark of the larger consulting shops and we offer 100% coverage from top tier health/dental plans. We have lots of other perks for full-time employees like paid conferences, etc.

Telecommuting: Yes, almost exclusively. Travel is an option if you want it, but it's currently ~1% of our total work.

Contracting/Full-time: Our preference is Full-time, if you're awesome and don't want to be an FTE email us anyways.

Location: We're looking for folks in -8 GMT through +1 GMT timezones.

Clearance: Nope, we don't work in that field. Look elsewhere for WannaCyberInASCIF? work.

Company Future: 1) Do fun hacks with awesome clients 2) Have fun doing it 3) Can we do something awesome research/products/service wise? if not...4) Reinvest profits to GOTO #1.
