Type of employment


"Cutting-edge research requires excellent minds – particularly more females – at all levels. Launch your mission with us and send in your application now!" Prof. Pascale Ehrenfreund - Chair of the DLR Executive Board

Abridged English version

The Optical Communication Systems Group develops – among other things – optical communication systems for aircraft and small satellites. Furthermore, it carries out measurement- and demonstration-campaigns, either with systems developed by DLR or in international cooperation. Therefore, the group operates the Optical Ground Station Oberpfaffenhofen (OGS-OP) as well as the Transportable Optical Ground Station.

Examples of systems that have been developed by the group are the Free-Space Experimental Laser Terminal II (FELT II), which has been tested aboard DLR’s Dornier 228 since 2008. Furthermore, within the project OSIRIS, optical communication systems that are optimized especially for small satellites are developed. In order to enable robust communication links, the group also deals with the development and implementation of Forward Error Correction (FEC) algorithms which are optimized for free-space optical communication links.

Your tasks include:

  • participation in challenging research projects concerning free-space optical communication systems for satellites, especially within DLR’s OSIRIS program
  • design and Development of software for space payloads and the accompanying ground segment in C++ or similar
  • design and development of the software for the ground based experimental setups like free space optical channel emulator etc.

Your qualifications:

  • successfully finished scientific studies in informatics, space technology with software focus, or similar studies (Master)
  • knowledge and practical experience in the software architecture and design
  • extensive programming skills in C++(11/14/17)
  • very good knowledge of the interfaces between software and FPGA-systems
  • good understanding of UNIX based operating system architecture and systems programming
  • practical experience in testing and debugging software for Embedded Systems
  • hands-on experience with version control and build tools (e.g. svn, scons) for software development in a team
  • basic knowledge in Space technology and the software-development for Space-applications desirable
  • basic knowledge of project management desirable

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (m/f/non-binary). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
