Ph.D. Student and/or Postdoc
IBM Research, Zurich
The IBM cryptography research group in Zurich is looking for a Ph.D. student and/or a post-doctoral scholar to work in the area of lattice-based zero-knowledge proofs.

The ideal candidate should have:

  • Very good implementation skills – preferably in C or C++
  • A solid mathematical background – e.g. abstract algebra and some basic familiarity with algebraic number theory is a plus
  • High motivation for creating efficient theoretical cryptographic designs and turning them into prototypes and high-quality optimized implementations
  • Papers in top cryptography conferences (for the post-doc position)
  • Prior experience working with ZK proofs (not necessarily lattice-based) is a plus

    This position is funded by a European ERC project, and all its output will be open source and patent-free. So a positive attitude towards contributing to the open source community is also a requirement.

    The IBM research lab is located in Ruschlikon, a lakeside town that is reachable in 10 minutes by direct public transport from central Zurich. English is the working language at the lab, and it is also widely understood and spoken in Zurich and its surrounding regions.

    The group offers very good working conditions, with the majority of our time being spent purely on research activities. It is also currently one of the leading research groups in quantum-safe cryptography, with some of its members (Luca de Feo, Vadim Lyubashevsky, and Gregor Seiler) significantly contributing to the invention, design, and implementation of several finalists in the ongoing NIST post-quantum standardization effort.

    To apply, please include a C.V., a brief motivation letter, and the names and email addresses of two references. If you have contributed to open source projects, please include a link to the repository and a brief explanation of your role. The starting date is flexible, but the sooner the better.

  • Contact: If interested, please send the application to: Vadim Lyubashevsky;; with "ZK APPLICATION" as the subject line
