The Physikalisch-Technische Bundesanstalt (PTB) is the National Metrology Institute of the Federal Republic of Germany with scientific and technical service tasks. It furthers progress and reliability in metrology for society, the economy and science. Artificial Intelligence (AI) is growing into the health sector where increasing implementation of AI in various medical settings will have a major impact on patient care: AI-enabled tools offer the attractive prospect of enabling healthcare professionals to find solutions for complex problems in a time-efficient manner. AI systems do entail economic and social benefits, but they also bear risks. The PTB is working towards minimising these risks by providing a sound basis for trustworthy AI systems. To reinforce our interdisciplinary team in AI research for the duration of 3 years starting by 1 June 2021, we are looking for:

• have prior research experience in a field relevant for the respective project (if applying for a postdoc position)
• work well-structured independently as well as in a team
• have excellent communication skills in spoken and written English
• are apt to write and present scientific papers
• are willing to travel between the sites of PTB and to other locations in Germany and abroad
• are eligible for a work permit for Germany

We offer:

• A one-week summer school for cross-project familiarization with the overarching topic
• Intensive PhD supervision by an interdisciplinary team
• Excellent national and international connections
• A position at one of the world’s leading research institutions with an excellent infrastructure
• Remuneration in accordance with the collective bargaining agreement for the public service (at the federal level) including special annual payments and capital forming benefits

For further information related to these positions, please contact:
Dr. D. Auerbach, phone: 0531 592-3102, e-mail: david.auerbach@ptb.de, or Dr. H. Rabus, phone: 030 3481-7054, e-mail: hans.rabus@ptb.de. PTB promotes the professional equality of women and men and is thus especially interested in applications from women. Within the scope of the official feasibilities, PTB offers flexible part-time work schemes in order to support, in particular, the compatibility of work and family life. Disabled persons will be given priority if they have the same occupational aptitude. Shortlisted candidates will be invited to online interviews taking place between 15th and 31st March 2021. The interviews consist of two parts: The first part includes the actual interview as well as a presentation in which the applicants summarize a publication selected from this list and a subsequent technical discussion. In the second part, bilateral discussions take place with the scientists responsible for the projects. Are you interested? Then we are looking forward to receiving your application that includes:

• curriculum vitae (filled in this template)
• bachelor‘s and Master‘s transcripts (for degrees obtained outside the EU please check at https://anabin.kmk.org/anabin.html whether they are acknowledged in Germany)
• high school certificates

Applicants for postdoc positions please also include:

• PhD certificate
• names and contact details of at least 2 references
