PNAS2501 Science and Development Positions

I.M. Systems Group Inc. IMSG (www.imsg) a sciencebased company providing professional scientific and technical support to the Federal government is leading a Team of prestigious companies to pursue the fiveyear service contract to support NASA Goddard Space Flight Center (GSFC) Global Modeling and Assimilation Office (GMAO). We are soliciting qualified candidates to fill multiple global numerical modeling and data assimilation positions including:

Scientists (in global numerical modeling data assimilation);

Scientific Programmer/Analyst;

Software Engineers;

Software Integration and Test Engineers;

System Engineers;

Graphics Systems Specialists;

Operations Analysts and

Mission Support / Administrative Analysts.

GMAO develops operates and maintains comprehensive models and data assimilation systems for the Earths atmosphere ocean land surface and cryosphere including atmospheric composition and ocean biogeochemistry. Collectively these Goddard Earth Observing System (GEOS) models and assimilation systems are configured to support NASAs Earth Science missions research activities and applications with emphases on research and innovation. GEOS systems also contribute to our nations capabilities in climate weather and environmental analysis and prediction. The data assimilation systems comprise the assembly preprocessing quality control and characterization of all the observations being assimilated the analysis systems which combine model and observation information and the Earth system models required to interface with the analysis systems.

GEOS models and assimilation systems are developed using existing software frameworks such as the Earth System Modeling Framework (ESMF); they are presently transitioning to adopt new data assimilation capabilities using the Joint Effort for Data assimilation Integration (JEDI); they rely heavily on leadingedge highperformance computing platforms. These highly configurable systems are developed and maintained using modern software practices within a complex ecosystem consisting of semiindependent packages many of which are shared with partner institutions. The GMAO collaborates within NASA and with the external science community in developing and validating its models and data assimilation systems. These positions will support the comprehensive range of GMAO research development and production activities.

The vast majority of GMAO activities require extensive expertise in both science and software development.

Ideal candidates will have a suitable education background (e.g. PhD and MS degrees in relevant disciplines) and proven working experience on similar science and systems.
