Job Description

Future. Discover. Together.
We develop innovative systems for wireless communication using light and are looking for support in implementing them on FPGAs. Optical wireless communication uses light to transmit information wirelessly. This enables cellular networks with ultra-high data density and very low latency, as well as increased security due to limited propagation. The technology is expected to complement WiFi and 5G-based networks in the future and is also likely to become part of the sixth generation of mobile communications (6G). Become a part of our team and join us on our journey of research and innovation!

Be part of change

• Design and development of IP cores for low-latency, high-throughput digital signal processing
• Simulation and verification of the implemented algorithms with test vectors
• Integration of IP cores into an OFDM-based Physical Layer
• Debugging of implemented designs in a LiFi testbed
• Collaboration within the team to optimize system design regarding reliability and functionality

What you contribute

• You are studying Technical Computer Science, Computer Science, Electrical Engineering, Communication Technology, or a similar field
• Knowledge or interest in digital signal processing and wireless communication systems (OFDM, MIMO, …)
• Proficiency in a hardware description language (VHDL or Verilog)
• Ideally, initial experience with FPGAs (Xilinx Vivado, Zynq Ultrascale+, …)
• Ability to work independently, willingness to learn, and interest in the subject matter

What we offer

• Fascinating challenges in a scientific and entrepreneurial setting
• Open and cooperative working atmosphere in an international team
• Modern and excellently equipped workspace in central location
• Opportunities to write a master's or bachelor´s thesis
• Flexible working hours

The position is initially limited to 1 year. An extension is explicitly desired.

The monthly working time is 80 hours. This position is also available on a part-time basis. We value and promote the diversity of our employees' skills and therefore welcome all applications – regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, sexual orientation and identity. Severely disabled persons are given preference in the event of equal suitability. Our tasks are diverse and adaptable – for applicants with disabilities, we work together to find solutions that best promote their abilities.
