We Offer

Unique Area of Expertise

Difficult and interesting work at the forefront of cryptography: zero knowledge proofs, private information retrieval, smpc and other fascinating problems in the applied field. We work with a full cycle of modern cryptographic problems: from scientific papers and mathematics, test implementation and PoC, to production-ready implementation of cryptographic controls in software.
Public track record in the Open Source part of the products and the opportunity to participate in research projects with companies that are moving different parts of applied cryptography in finance, distributed computing and privacy-enabling technologies forward.
Work at the intersection of technologies: cryptography, software engineering, information security. You won’t be bored :)
A sense of meaning and responsibility for those who have been tamed - your code will work for many years in large and small systems, from data protection in power plant management to advanced cryptocurrencies.

Environment

Friendly and experienced team: smart people to learn from, great people to build with. Each of us is unique, we value and support each other.
An atmosphere that motivates you to grow and get smarter every month, a healthy ratio of routine / experimentation.
Trust: schedule, reporting, bureaucracy is kept at reasonable minimum. We hire smart people and trust them to do the right thing. When things go wrong, we help rather than punish.
Shared decision making.
Friendly to humans: not just a formal vacation and sick leave quota. Feel like your mental or physical wellbeing needs care? Take some time off. Feel like working a few days from home? Sure. As long as you’re in line, we are here to support you when you’re not.

Growth

Team that facilitates internal learning and growth all the time.
Interesting technologies to work with - sometimes, even unique ones (we design applied cryptography schemes and techniques and novel ways to use them).
Ability to grow into one of the fastest growing industry sectors (computer security) with a team of experienced professionals.
Management attention to help you improve upon your personal goals (through regular 1:1s and mentoring).

Benefits

Competitive compensation with flexible bonus scheme.
Sick leaves, 21 vacation days a year, extra days off - according to agreements and laws.
Conferences, books, courses - we encourage learning and sharing with the community. Our team members share a lot in talks, workshops and blog posts.

Not Sure but Considering? Talk to Us

If you see yourself fit but a few things are off - don’t hesitate to talk anyway. It might be that your unique combination of skills and knowledge would be perfectly fitting for our environment, but we both just don’t know it yet.

How to Apply

We'd like to get your CV to start a conversation. A supporting letter explaining your story, your interest in cryptography, what you have done in the past and what kind of work you find interesting would help, but is not necessary.
