for Neutron Research (NCNR) in Gaithersburg, MD is seeking candidates for full
time work in computer software development for data acquisition and control related
to materials research carried out with facilities at the NCNR.</p><p class="MsoNormal" style="text-align:justify"><o:p> </o:p></p><p class="MsoNormal">The NCNR is a national user facility that develops and makes
available to the general scientific community advanced instrumentation for
materials research using beams of cold neutrons. The laboratory serves almost
2000 guest scientists per year with about 20 experiment stations. More
information about the NCNR can be found at the web site

data acquisition and control systems used on its neutron scattering instruments.
Major effort is needed for:</p>
<ul style="margin-top:0in" type="disc">
<li class="MsoNormal" style="mso-list:l0 level1 lfo1;tab-stops:list .5in">Development
of instrument control software and supporting libraries using Java, Python
and C/C++.</li>
<li class="MsoNormal" style="mso-list:l0 level1 lfo1;tab-stops:list .5in">Creation
and maintenance of use cases, UML diagrams and wire frames from
stakeholder requirements.</li>
<li class="MsoNormal" style="mso-list:l0 level1 lfo1;tab-stops:list .5in">Aid in
the development of unit and functional test plans for system verification.</li>
<li class="MsoNormal" style="mso-list:l0 level1 lfo1;tab-stops:list .5in">Perform
unit and system level testing.</li>
<li class="MsoNormal" style="mso-list:l0 level1 lfo1;tab-stops:list .5in">Provide
software support maintenance and user documentation for instrument control
software. </li>
</ul><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">This software is required to provide robust, responsive,
real-time control of instrument hardware, (<i>e.g</i>. servo and stepping
motors, encoders, rotary and translation stages, multiple neutron counters,
process controllers, etc.), and to provide an intuitive, easy-to-use graphical
interface for displaying, managing and processing neutron scattering data<span style="color:red">. </span>Assistance is also needed in the development of
training materials and courses to enable users and instrument scientists to
customize the software for instrument-specific purposes.<span style="color:

must have, or be working toward, a bachelor's degree in computer science,
mathematics, engineering or a physical science and possess good written and
verbal communication<span style="color:red"> </span>skills<span style="color:red">.</span> Candidates without a computer science degree must
have completed computer science course work or have experience working as a
software engineer. Preference will be given to candidates who have experience
in computer systems programming, embedded systems programming, network programming,
object oriented design and development in C/C++, Python, and Java on the Linux
and Windows platforms. </p><p class="MsoNormal" style="text-align:justify"><o:p> </o:p></p><p class="MsoNormal" style="text-align:justify">Depending on experience,
compensation is in the range from $25./hour to $43./hour, plus benefits for
full time work.</p><p class="MsoNormal" style="text-align:justify"><o:p> </o:p></p><p class="MsoNormal" style="text-align:justify">Expressions of interest may be
