Quantstamp is looking for an applied cryptographer. Quantstamp often deals with a wide range of cryptographic problems, including reviewing implementations, providing implementation guidance (e.g., for clients), and tackling new theoretical problems using cryptography. For example, Quantstamp regularly receives requests to review code bases which either invoke or implement (custom) cryptography, as part of an audit. Zero knowledge applications are becoming more common across all ecosystems, and this kind of math will also soon be the basis of several scaling solutions - in particular, zero knowledge rollups. These applications often use a zero-knowledge Succinct Non-interactive Argument of Knowledge (zk-SNARK) proof system, or a zero-knowledge Succinct Transparent Argument of Knowledge (zk-STARK) proof system.


Your day-to-day work will involve doing research about various cryptographic protocols. Some protocols of interest will be those found in the code of our audit clients, others will be protocols of interest for future audits. In particular, in anticipation of audits of, or for, zero-knowledge rollup systems, you’ll be asked to understand various zero-knowledge proof systems. There are a lot of those - we don’t expect mastery in all of them, but mastery of at least one would be ideal. You may be asked to compare and understand systems you’re not familiar with, and you should be comfortable doing this. Ideally you have a strong theoretical background but can also read and write code (the specific language is not too important). You will talk to other researchers within the company and may be asked to talk to clients directly, in a technical capacity.


Need to haves

  • Mastery of at least one zk-SNARK/zk-STARK proof system (e.g., PLONK, HALO/HALO2, Groth16, Bulletproofs), or a strong enough technical background to understand one (and this should have some direct connection to cryptography)
  • Ability to code and develop software. You should have experience with at least one major language, like Rust, Python, Java, or C; the exact language is not too important. You should be familiar with versioning software (specifically, GitHub), testing, and a familiarity with algorithms and data structures. 
  • Knowledge of cryptographic primitives or concepts, like elliptic curve cryptography, hash functions, and PCPs.
  • Ability to read and interpret academic papers
  • Ability to communicate ideas
  • Partial availability (2-6h) during EST work hours to allow for communication with the team.


Nice to haves

  • Familiarity with existing ZK Rollup designs
  • Familiarity with multiple ZK proof systems
  • Strong coding ability
  • Knowledge of software development in Solidity, including testing and various development frameworks like Hardhat.
  • Familiarity with blockchain ecosystems, particularly Ethereum
  • Familiarity Circom for writing zero knowledge circuits


Compensation & Perks

  • Competitive compensation package (commensurate to experience) + performance and referral bonuses.
  • 100% remote and flexible working hours. Work from anywhere in the world.
  • Generous paid time off, including maternity/paternity leave.
  • Retirement/pension plan.
  • Equity
  • Rent your own desk in a co-working space or work from anywhere at any time.
  • Free gym membership or any virtual alternative of your choice.
  • Learn about the hottest and newest products and trends in the crypto space before they appear on any news outlets.
  • Join quarterly all-expenses-paid retreats in exotic/exclusive locations with the whole team.

Is cryptography a good career?

Cryptography can be a very rewarding and fulfilling career for those who are interested in mathematics, computer science, and security

Cryptography is the science of protecting information from unauthorized access or modification, and it plays a critical role in information security

With the increasing need for secure communication and transactions in our digital world, there is a growing demand for professionals with expertise in cryptography

Cryptography professionals can work in a variety of fields, including government agencies, financial institutions, technology companies, and more

Cryptography requires strong analytical and problem-solving skills, as well as an understanding of algorithms and programming

In addition, communication skills are important, as cryptography professionals often work in teams and must be able to explain complex concepts to non-technical stakeholders

If you have a strong interest in mathematics, computer science, and security, and enjoy solving complex problems, cryptography can be an excellent career choice with many opportunities for growth and advancement.
