NASA Support Scientific Software Developer

Job Description

Description

Atmospheric Aerosol and Chemistry Programming Support Scientist 

SAIC is seeking a scientific programmer/analyst to support the Global Modeling and Assimilation Office (GMAO) and Atmospheric Chemistry and Dynamics Laboratory (ACDL) at NASA/GSFC in the development of the GEOS Earth System Model (ESM) and Data Assimilation System (DAS).

The position entails code development and testing related to the implementation and enhancement of atmospheric simulation capability in the GEOS ESM, including especially work on aerosols, trace gases, and chemical processes.   The position offers a unique opportunity to join a team that specializes in aerosols, stratospheric ozone chemistry, and tropospheric air pollution, including their interactions with interannual variations and long-term changes in the atmospheric circulation and human activities (e.g., pollutant emissions).  Specific tasks include development of code to handle the interface to new aerosol and chemistry modules, the integration of new or updated aerosol and chemistry modules from other developers, the maintenance of code bases in the "Earth System Modeling Framework" repository, updating emission inventories needed, and the testing and validation of updated codes and model configurations.  The work also involves the use of NASA's long records of satellite observations of atmospheric composition to evaluate the realism of the GEOS ESM simulations. 

This position is designed for an early to mid-career scientific programmer with experience writing Fortran code for large modeling systems, with some background in atmospheric chemistry and/or aerosols, and with a desire to develop new skills in computing and/or scientific discovery while contributing to the further success of this collaborative project at NASA GSFC.

Career-growth opportunities include the possibility of interacting with a broad range of NASA scientists with skills in Earth observation, atmospheric transport and composition modeling, and high-performance computing. 

Qualifications

TYPICAL EDUCATION AND EXPERIENCE:

REQUIRED

• MS in Atmospheric Science, Atmospheric Chemistry, Computer Science, or related field and Three (3) or more years of experience in programming in a high-performance (parallel) computing environment or equivalent combination of education and experience.
• Strong Fortran and Python programming skills.
• Knowledge of atmospheric chemistry and/or circulation models
• Solid communication skills, both oral and written

DESIRED

• PhD in Atmospheric Science, Atmospheric Chemistry, Computer Science, or related field
• Experience in shell scripting or C.
