Research Software Developer / Scientist (m/f/d) Deep Learning for X-ray Tomography

Reference code: 50025282_2 ‚Äď 2020/WP 6
Commencement date: as soon as possible
The place of employment is Hamburg

Helmholtz Zentrum Geesthacht (HZG) operates an outstation at DESY in Hamburg in order to provide access to highly brilliant synchrotron radiation within its German Engineering Materials Science Centre (GEMS). At the PETRA III synchrotron radiation source, HZG jointly operates the High Energy Materials Science Beamline (HEMS, P07), the Imaging Beamline (IBL, P05) and the Nanofocus Endstation of Micro- and Nanofocus X-ray Scattering Beamline (MINAXS, P03) along with supporting laboratory instrumentation.

HZG is a partner in the collaborative Helmholtz.AI funded project ‚ÄėUniversal Segmentation Framework‚Äô (UNISEF). The project involves the development and implementation of methods for the optimization of X-ray tomography datasets. This includes the automatic selection of the most suitable deep-learning segmentation architecture, a guided interactive and iterative strategy for the annotation of training data and the deployment of a browser-based service. Furthermore, the development and implementation of novel deep learning architectures for the segmentation of identical objects (instance segmentation) is addressed.

We invite applications for a Research Software Developer / Scientist (m/f/d) Deep Learning for X-ray Tomography in our outstation at DESY Hamburg. The position is initially limited to 2 years.

Your tasks

  • development and implementation of quality metrics for the evaluation of deep-learning based segmentations

  • development and implementation of convergence criteria for the interactive annotation strategy

  • implementation of a pipeline for semi-automatic segmentation (2D)

  • implementation of a pipeline for fully automated denoising of images

  • integration of above methods in a web service and the HPC environment at DESY

  • annotation of tomographic data for the training of neural networks

  • application of the developed algorithms and framework

  • collaborate closely with project partners and the Helmholtz.AI framework

  • publish and present scientific results at international conferences and workshops

Your profile

  • master degree (or higher) in computer science, physics, mathematics, life science or equivalent

  • knowledge in the areas of artificial intelligence, deep/machine learning and image processing

  • strong background in deep learning and software/algorithm development

  • fluent in modern programming languages

  • experience with web services and frameworks is an asset

  • experience in X-ray tomography is an asset

  • good spoken and written command of the English language

  • team player with good communication skill.

We offer
