At Ripple, we’re building a world where value moves like information does today. It’s big, it’s bold, and we’re already doing it. Through our crypto solutions for financial institutions, businesses, governments and developers, we are improving the global financial system and creating greater economic fairness and opportunity for more people, in more places around the world. And we get to do the best work of our career and grow our skills surrounded by colleagues who have our backs.Â
If you’re ready to see your impact and unlock incredible career growth opportunities, join us, and build real world value.
THE WORK:
For this role, we are looking for motivated individuals with expertise in the latest blockchain cryptography and security. This high-impact role allows you to shape the vision and the future of the team.
A successful candidate will design new cryptographic systems based on the Crypto 2.0 standards: multi-party computation protocols, homomorphic encryption, and zero-knowledge proofs. These systems generate and manage cryptocurrency wallet keys and sign transactions in environments with mutual distrust, where multiple parties are engaged in joint computational work. Â
WHAT YOU’LL DO:
A candidate will be responsible for:
- Technical analysis of academic whitepapersÂ
- Research and implementation of elements of cryptographic systems
- Validating results with rigorous proofs
- Collaboration with the engineering team, commitment to writing a code
- Performing security assessments
- Presentation of Ripple research to the community via active participation in standards bodies, academic conferences, and social media.Â
- Participation in workshops and hackathons.
WHAT YOU’LL BRING
- 5+ years of relevant experience in the field of cryptography.Â
- Excellent knowledge of number-theoretical problems related to asymmetric cryptography, hash functions, commitments, and digital signatures.Â
- Experience in homomorphic encryption, identification protocols, and zero-knowledge proofs.
- Experience in multi-party computation.
- Analytic skills and the mindset of a continuous learner.Â
- Experience in one or more programming languages: Scala, Rust, C++, or Python.
* Accountability, an ownership of the end-to-end result.
- A passion for sharing knowledge with your team, the organization, and a broader community.Â
- Fluency in English.
Bonus to have
- Knowledge of consensus protocols
- Hand-on experience in Rust language and its ecosystem
Education
Master's or PhD degree in cryptography, mathematics, or a similar field.
WHO WE ARE:
Do Your Best Work
- The opportunity to build in a fast-paced start-up environment with experienced industry leaders
- A learning environment where you can dive deep into the latest technologies and make an impact. A professional development budget to support other modes of learning.
- Thrive in an environment where no matter what race, ethnicity, gender, origin, or culture they identify with, every employee is a respected, valued, and empowered part of the team.
- In-office collaboration for moments that matter is important to our culture, and we give managers and teams the flexibility to decide which 10+ days a month they come in.Â
- Weekly all-company meeting - business updates and ask me anything >
- We come together for moments that matter which include team offsites, team bonding activities, happy hours and more!
Take Control of Your Finances
- Competitive salary, bonuses, and equity
- Competitive benefits that cover physical and mental healthcare, retirement, family forming, and family support
- Employee giving match
- Mobile phone stipend
Take Care of Yourself
- R&R days so you can rest and recharge
- Generous wellness reimbursement and weekly onsite & virtual programming
- Generous vacation policy - work with your manager to take time off when you need it
- Industry-leading parental leave policies. Family planning benefits.
- Catered lunches, fully-stocked kitchens with premium snacks/beverages, and plenty of fun events
Benefits listed above are for full-time employees.Â
What is Zero-knowledge?
Zero-knowledge is a concept in cryptography that allows two parties to exchange information without revealing any additional information beyond what is necessary to prove a particular fact
In other words, zero-knowledge is a way of proving something without actually revealing any details about the proof
Here are some examples of zero-knowledge:
- Password authentication: When you enter your password to log into an online account, the server doesn't actually know your password. Instead, it checks to see if the hash of your password matches the stored hash in its database. This is a form of zero-knowledge because the server doesn't know your actual password, just the hash that proves you know the correct password.
- Sudoku puzzles: Suppose you want to prove to someone that you've solved a particularly difficult Sudoku puzzle. You could do this by providing them with the completed puzzle, but that would reveal how you solved it. Instead, you could use a zero-knowledge proof where you demonstrate that you know the solution without actually revealing the solution itself.
- Bitcoin transactions: In a Bitcoin transaction, you prove that you have ownership of a certain amount of Bitcoin without revealing your private key. This is done using a zero-knowledge proof called a Schnorr signature, which allows you to prove ownership of a specific transaction output without revealing the private key associated with that output.
- Secure messaging: In a secure messaging app, you can prove to your contacts that you have access to a shared secret without revealing the secret itself. This is done using a zero-knowledge proof, which allows you to prove that you have access to the secret without actually revealing what the secret is.
