<p><span lang="EN-US">We are looking for a brilliant C++ developer for our team in Copenhagen, Denmark, who wants to play a central role in developing our high-performant scipp library for processing of multidimensional experimental data even better. We are
using modern C++ combined with Python and constantly strive to improve our skills and stay abreast of modern scientific software development. For more information on the scipp library, see

<p><strong><span lang="EN-US" style="font-family:"Calibri",sans-serif">Description of employer</span></strong><span lang="EN-US"><br>
The European Spallation Source ERIC (ESS) is currently under construction and will become the most powerful neutron source in the world once in full operation. ESS will run a user program that will serve thousands of scientists per year, who will make use of
the unique properties of neutrons to investigate structure and dynamics of materials ranging from atomic to macroscopic scales. Once ESS is in steady-state operation, these experiments are estimated to generate peta-bytes of data per year that need to be processed
in order to generate scientific value. Our current development of scipp forms the basis for this endeavor and is crucial for the scientific impact of ESS. In addition to scipp (</span><a href="https://scipp.github.io/"><span lang="EN-US">https://scipp.github.io</span></a><span lang="EN-US">)
we are also a core member of the international Mantid collaboration (</span><a href="https://mantidproject.org/"><span lang="EN-US">https://mantidproject.org</span></a><span lang="EN-US">) that jointly develops the Mantid software for data processing (</span><a href="https://github.com/mantidproject/mantid"><span lang="EN-US">https://github.com/mantidproject/mantid</span></a><span lang="EN-US">).<o:p></o:p></span></p>
<p><span lang="EN-US">The developer will become a member of the Data Reduction, Analysis and Modelling (DRAM) group located in central Copenhagen, Denmark at the ESS Data Management and Software Centre (DMSC), part of the ESS Science Directorate. The DRAM group
is in charge of providing support and software for data processing for all the beamlines at ESS. This software is critical for making experiments at ESS successful. The group currently has ten members and is expected to grow in the coming years. The group
members have mixed backgrounds in scientific computing, software development, and the natural sciences at the PhD level.<o:p></o:p></span></p>
<p><span lang="EN-US">The group engages in international open source software and research projects, particularly with other European neutron sources, but also with photon sources and universities, all with the aim of increasing the scientific impact of the
ESS user program. </span>Examples of other software projects that the group leads or contributes to are SasView (<a href="http://sasview.org/">https://sasview.org</a> /

<a href="https://github.com/easydiffraction">https://github.com/easydiffraction</a>). Characteristic for that software is that they take the outcome from scipp and / or Mantid as input for further analysis.<o:p></o:p></p>
<p>The group takes pride in its competence development and all group members are expected to contribute to the further development of the group and its capacities along with development of their own individual skills and competences.<o:p></o:p></p>
<p>The scipp development team in Copenhagen collaborates closely with developers at the neutron source ISIS in the United Kingdom, in essence operating as one distributed team with daily standup meetings and regular hackathons.<o:p></o:p></p>
<p><strong><span style="font-family:"Calibri",sans-serif">Job description and responsibilities</span></strong>
<br>
We are currently looking into expanding our group with a highly motivated and skilled C++ developer who will become an important contributor to our processing software scipp for the critical step between data acquisition and data analysis of instrument data.
This so-called data reduction step makes acquired detector counts and associated metadata scientifically useable. The objective is to make scipp suitable for handling the high data rates at ESS, and an efficient tool for rapid development of workflows tailored
to specific scientific instruments. It is therefore important that you are able to work with scientists to gather and distill requirements and understand the basics of the underlying physics.
