Scientist Optical non-terrestrial networks

Future. Discover. Together.

Excellent research and innovation are at the centre of the work of the HHI - Fraunhofer Institute for Telecommunications. We are a world leader in researching mobile and optical communication networks and systems, as well as machine learning, computer vision and compressing digital videos. Become a part of our team and join us on our journey of research and innovation!

What you will do

• This position is part of the PhD project under Horizon Europe MSCA Doctoral Networks "FOCAL" (): Architecture design and effective routing for optical multi-layered space/aerial networks Carry out research projects on classical and quantum optical communications

• You will investigate efficient architecture of non-terrestrial networks (NTNs): how to reach high connectivity with less resources. That includes:

  • The modelling of network nodes, terminals and communication channels

  • The quality assessment of end-to-end connections and the description of handover solutions

  • The consideration of quantum key distribution (in addition to classical optical communication links)

• Your PhD will be co-supervised by the project partners Technical University of Berlin and Thales Alenia Space (France)

• You will visit project partners during the project to help you carry out your work packages

• You will exploit the project results for dissemination (e.g. conferences) and production of intellectual property

What you bring to the table

• Outstanding scientific master degree in electrical engineering, physics or similar

• Programming skills (e.g., C/C++, Python, Matlab, …) for device control, data analysis, and simulations

• Theoretical and experimental knowledge of optical systems (e.g. optical components, optical propagation, single-photon processing, …), communication systems and high-speed electronics.

• Professional commitment

• Team spirit, ability to work independently and autonomously

What you can expect

• Fascinating challenges in a scientific and entrepreneurial setting

• 30 vacation days

• Modern and excellently equipped workspace in a central location

• Great and cooperative working atmosphere in an international team

• Flexible working hours

• Support if you wish to do a doctorate

• Opportunities to work from home

• Extensive training-, health- and sports offers

• Various employee discounts and discounted BVG ticket

• Offers for families (parent-child office, emergency care, leisure activities, etc.)

The position is initially limited to 3 years. An extension is explicitly desired.

The weekly working time is 39 hours. This position is also available on a part-time basis.
