International Association
for Cryptologic Research

We have an opening of two PhD positions (one starting September 2025, one starting in 2026) and 1 postdoc (starting September 2025) in the Foundational Cryptography group at IBM Research Zurich. The PhD positions are fully funded for 4 years. The Foundational Cryptography team currently consists of 9 permanent researchers and 7 PhD students.

The research project that the students and postdoc will be working on is about developing post-quantum cryptographic algorithms for human authentication, PIN-based protocols, and the IoT. A background in any of lattice-based cryptography, multi-party computation, or password-authenticated key exchange is helpful but not a requirement. We will explore both theoretical limitations and usable solutions, and depending on the interest of the applicant, either a more foundational or practical direction can be taken.

Applicants need to have a passion for the mathematical analysis of algorithms in general and cryptography in particular. A master's degree in mathematics or computer science and fluently written and spoken English is required.

The IBM Research Zurich lab is located on the beautiful Lake Zurich, close to the Swiss Alps. Research divisions include IT Security, Quantum, AI, and Hybrid Cloud Systems. IBM fosters an inclusive and diverse working environment. Applicants from minorities are particularly encouraged to apply.
