The Plant Sciences Division (IBG-2) of the Institute of Bio- and Geosciences (IBG) investigates the dynamics of plant processes and the interaction of plants with the environment. Plant science at Forschungszentrum Jülich plays a leading role at national and international level in the field of plant phenotyping, i.e. in the quantitative and non-invasive recording of structural and functional properties of plants. In particular, we develop new sensor technology and measurement concepts and integrate them into semi- and fully- automated systems, as well as we deploy the corresponding IT infrastructure. One of these systems, is a world-wide unique high-throughput facility for automated, non-invasive characterization of hundreds of roots and leaves of plants using optical sensors. Data analysis includes workflows, which make use of the most recent machine learning methods.

We are looking to recruit a

Computer Scientist / Software Developer – Image Processing for Quantification of Plant Properties

Your Job:

  • Development of new or available algorithms (evaluation and benchmarking) for root recognition and classification from digital images
  • Application and parameterization of suitable frameworks or algorithms for image processing with a focus on machine learning and deep learning
  • Increase the throughput of image analysis of root images
  • Optional: Development of workflows for image processing and data extraction for daily operation and linking workflows with existing in-house developed databases

Your Profile:

  • Completed studies (Bachelor) in computer science or comparable discipline
  • Extensive experiences with the application of deep learning methods (supervised learning, convolutional neural networks, semantic image segmentation) and relevant basics in deep learning frameworks (e.g. Tensorflow, PyTorch)
  • Experience with digital image analysis and feature acquisition from monochrome and RGB images
  • Proven experience with programming languages and software (C++, Phyton, Matlab etc.)
  • Ideally, practical experience with optical measuring stations (e.g. also from the biomedical field) and their components such as camera types and lighting conditions
  • A high degree of initiative, responsibility and team spirit
  • You are fluent in German and have a good command of the English language

Our Offer:

  • Working at one of the largest and best-known European research facilities with excellent scientific and technical infrastructure
  • Opportunity to work in a team of highly-motivated scientists and technicians in an international, interdisciplinary working environment on an attractive research campus, ideally situated between the cities of Cologne, Düsseldorf, and Aachen
  • Promotion of professional development through various training programs
  • Flexible working hours and various opportunities to reconcile work and private life
  • Limited for 2 years with possible longer-term prospects
  • Full-time position with the option of slightly reduced working hours
  • Salary and social benefits in conformity with the provisions of the Collective Agreement for the Civil Service (TVöD)
