Faculty of Computer Science:
Horst Görtz Institute for IT Security – The Cluster of Excellence CASA

About CASA:
The Cluster of Excellence "CASA:
Securing the Digital Society" will be funded by DFG for the years 2026‑2032 with approximately 43 million euros. CASA aims to strengthen the resilience of our digital society. The emergence of disruptive technologies in recent years, especially artificial intelligence and quantum computers, has caused substantial new challenges for cybersecurity research. In the second funding phase, CASA will specifically address these challenges.

Thematic priorities include the security of quantum technologies, protection against AI‑based disinformation and societal polarization, and new approaches to defending against ransomware. In addition to technical questions, it also investigates the interaction of human behavior and cybersecurity. Research at CASA, which is based at the Horst Görtz Institute for IT Security, follows a strongly interdisciplinary approach. Researchers from the fields of computer science, cryptography, electrical engineering, mathematics, and psychology work together in a unique constellation in Europe.

This holistic approach is unparalleled and holds the potential for scientific breakthroughs.

Ruhr‑University Bochum (RUB) and its Faculty of Computer Science offer an excellent environment for aspiring young researchers. Some 20 years ago, the Horst Görtz Institute for IT Security (HGI) was founded here. It is now one of Europe's most prestigious institutions for basic computer security research. The HGI maintains extensive networks with leading research institutions worldwide and with media and industry.

Moreover, it has produced numerous successful security startups. The pioneering work of the HGI forms the basis for the Cluster of Excellence CASA.

• Scope: full‑time
• Duration: fixed‑term, 2 years
• Start: at the earliest possible date
• Apply by: 2026‑02‑02

• Our goal is to attract postdoctoral researchers and enable them to conduct their research with the mentorship of a PI. We expect that within the duration of this contract, candidates will be able to achieve independent achievements in research, e.g. through publications or joint research endeavours.
• Therefore, we are permanently looking for excellent candidates with outstanding doctoral degrees in computer science, electrical engineering, mathematics and psychology (preferably with a relationship to technology) or related disciplines.
• We offer two‑year positions for postdoctoral candidates.

• An above‑average doctoral degree in computer science, electrical engineering, mathematics, psychology (preferably with a relationship to technology) or related disciplines is mandatory for the application.
• Fluent spoken and written English is also required.
• In addition, applicants should have basic knowledge of one or more of the research areas relevant to CASA:
  Cryptography, system security, hardware security, decentralized security, human‑centered security, AI and security.
• Postdoctoral students should already have published relevant papers at the leading conferences in cryptography and computer security research, as listed e.g. at (Sie können sich bewerben oder uns per E-Mail kontaktieren in dem Sie die untenstehende Online-Bewerbungsbox verwenden).

• Excellent research environment with award‑winning scientists,
• Programs designed to support parents,
• Support measures for women in IT security,
• Excellent support for doctoral researchers,
• Opportunities for academic and professional development,
• Budget for courses, conferences, equipment and international exchange,
• Open team culture.

The position is salaried and based on the collective agreement of the Länder (TV‑L). If the personal and collective agreement requirements are met, the employee will receive pay grade E13 TV-L. Further information can be found at  (in German). The place of work is Ruhr University Bochum. If the position is funded by third‑party funds the employee has no teaching obligation.
