The Center for Particle Physics in Siegen (CPPS) has an opening for

The ATLAS group in Siegen has responsibilities in the upgrade and the operation of the pixel detector, and has in-depth expertise in top-quark physics and flavour tagging. Collaboration with the local theory particle group is being strengthened.

The successful candidate is expected to carry out data analysis with Run-2/Run-3 ATLAS data, studying associated top-quark pair-production (tt̄Z, tt̄H, tt̄tt̄) or rare top-quark decays in final states with several leptons, thus probing new physics in so far unexplored regions. Skills in applying machine learning techniques will be acquired and/or improved.

Excellent applicants are encouraged to apply. They should hold (or about to complete) a master degree in high-energy physics or a closely related field and should have relevant experience with data analysis and object-oriented programming (C++, Python). The position is located at Siegen, a cozy, international University town, with the possibility of frequent travels to CERN and/or a stay of several months. Depending on the evolution of the pandemic, a remote start can be agreed. An attractive salary is offered.

The position is available immediately for an appointment of initially three years. Applications will be reviewed in the order they are received. The University of Siegen is an equal opportunity employer.

To apply, please prepare the following material and send it by e-mail to markus.cristinziani@uni-siegen.de before January 25th, 2022 to receive full consideration:

- CV, including your expected or past undergraduate degree date;

- Grade transcript, with an explanation of the grading scale used, if needed;

- Two reference letters to be sent to the e-mail address above from supervisors or University teachers who know your work;

- If English or German is not your first language, we would also like to have proof of your English language ability. If you have already taken an English language qualification, please include your certificate with your application. We will also consider your application without this document.

- Links to your master thesis (if available) and other relevant material, e.g. software projects (GitHub) or similar.

You are welcome to send questions or informal inquiries to Markus Cristinziani (markus.cristinziani@uni-siegen.de). More information can be found on our groups webpage https://www.hep.physik.uni-siegen.de/.
