International Association
for Cryptologic Research

We are looking for outstanding PhD students and postdoctoral researchers to join the cryptography group led by Dr. Michael Reichle at INSAIT in Sofia, Bulgaria. INSAIT is already a top research institute in AI and Theory and you have the opportunity to help shape INSAIT into a world-class research institute for Cryptography and Security. Sofia offers great gastronomy, an affordable cost of living and quick access to nature, with many parks and Vitosha Mountain just outside the city.

Topics. Research areas include post-quantum cryptography, protocols for signatures and encryption, and zero-knowledge proofs. Applicants with interests in related areas of cryptography are also encouraged to apply.

PhD applicants. You should hold (or be close to completing) a Master's degree and have a strong background in cryptography, theoretical computer science, mathematics, or a related field. The position is in collaboration with Google DeepMind with a PhD fellowship.

Postdoctoral applicants. You should hold (or be close to completing) a PhD in a related field. A strong research record, ideally including publications at IACR conferences or leading security venues, is preferred.

The positions are well funded and come with no teaching obligations. The start date is flexible, with positions available from October 2026 onward. Applications will be considered on a rolling basis until the positions are filled.
