<p><span lang="EN-US">The European Spallation Source, ESS, a partnership of European countries, is hiring motivated and inspired people to plan, design, and construct the world’s most powerful neutron source. We seek ambitious, talented people in different
fields who are excited about playing a part in the future of science in Europe.<o:p></o:p></span></p>
<p><span lang="EN-US">ESS can offer a variety of things, such as passionate and international colleagues, a vibrant melting pot of diversity, and a challenging, exciting and high paced work environment. We value and need expertise, innovative minds and great
ways of leading and interacting with people from all over the world.<o:p></o:p></span></p>
<h4><strong><span style="font-family:"Calibri",sans-serif"><a href="https://api.kaltura.nordu.net/index.php/extwidget/preview/partner_id/335/uiconf_id/23450475/entry_id/0_norye2s0/embed/auto?&flashvars%5BstreamerType%5D=auto"><span lang="EN-US">Come and change
the world with us!</span></a></span></strong><span lang="EN-US"><o:p></o:p></span></h4>
<p><span lang="EN-US">The ESS has jointly with Lund University been fortunate to receive a grant from the Swedish Research Council to research and develop new methodologies for processing and analysing data from the instrument NMX. NMX is optimized for neutron
macromolecular crystallography and is currently under construction.<o:p></o:p></span></p>
<p><span lang="EN-US">For this reason, the ESS, Data Management and Software Centre (DMSC) in Copenhagen, Denmark invites applications for a
<strong><span style="font-family:"Calibri",sans-serif">Computational Crystallographer
</span></strong>in the Data Reduction, Analysis, and Modelling (DRAM).<o:p></o:p></span></p>
<p><span lang="EN-US">The DMSC is a division of the Science Directorate and is responsible for the design, development and construction of the computer software and hardware to be used for the operation and data analysis of the experiments to be carried out
on the neutron scattering and imaging instruments to be constructed at ESS.<o:p></o:p></span></p>
<p><span lang="EN-US">The DRAM group is in charge of providing support and software for data reduction, analysis and modelling for all the beamlines at ESS. It currently has about 15 members with a mixed background in areas such as scientific computing and
software development, (computational) chemistry and physics, molecular biology and hard condensed matter. 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. Examples of such projects are scipp (</span><a href="https://scipp.github.io"><span lang="EN-US">https://scipp.github.io</span></a><span lang="EN-US">),
easyscience (</span><a href="https://easyscience.software"><span lang="EN-US">https://easyscience.software</span></a><span lang="EN-US">), and SasView (</span><a href="https://www.sasview.org"><span lang="EN-US">https://www.sasview.org</span></a><span lang="EN-US">).
As indicated by those projects, the group’s preferred programming languages (and that of the field) are Python and C++ with graphical user interfaces developed in the Qt framework. In the future the group will support users of ESS with analysis and modelling
associated with their experiments, as well as developing software and further developing the field.<o:p></o:p></span></p>
