<p class="MsoNormal">Description<o:p></o:p></p>
<p class="MsoNormal"><b>On-Call Scientific Software Engineer (Climate)<br>
<br>
</b><o:p></o:p></p>
<p class="MsoNormal"><b>Location: US Remote</b><o:p></o:p></p>
<p class="MsoNormal">ICF seeks a <b>Scientific Software Engineer </b>for the ClimateSight project, a cutting-edge initiative focused on scalable, distributed modeling of climate-related geospatial data. This position will collaborate closely with domain scientists
and technical experts to transform experimental code into robust, production-ready software. The engineer will lead efforts to refactor and optimize Python-based models for distributed computing using the Pangeo ecosystem, particularly Xarray and Dask, and
will help integrate these models into a modular, well-documented Python package.<o:p></o:p></p>
<p class="MsoNormal">The successful candidate will bring deep experience in scientific computing, object-oriented Python development, and cloud-based data workflows. They will be responsible for implementing memory-efficient stochastic modeling methods, managing
virtual environments, and ensuring compatibility with ARCO geospatial formats in AWS S3. This role requires a proactive, collaborative mindset and a commitment to building tools that are both high-performing and accessible to a broad range of users.<o:p></o:p></p>
<p class="MsoNormal">This is a remote, <b><u>on-call hourly </u></b>role that provides flexibility to work from zero to 20 hours per week.<o:p></o:p></p>

<p class="MsoNormal"><b>About On-Call Employment with ICF</b><o:p></o:p></p>
<p class="MsoNormal">Given the seasonal or project-specific nature of this project, ICF often hires professionals as “On-Call” employees. On-Call employees are scheduled for work hours as they become available (while we usually schedule work hours a few weeks
ahead of time, and each on-call employee is free to accept or refuse the hours assigned to them in a given week. On-Call employees may work concurrent projects outside of their ICF assignment (as long as their outside work does not create a conflict of interest
with the work they do for ICF).<o:p></o:p></p>
