Job Description:

The Space Radiation Analysis Group (SRAG) at the Johnson Space Center is seeking expertise in solar energetic particle event forecasting and space weather modeling to support NASA’s exploration class missions.  The successful candidate will leverage established and new model development with an understanding of current real time space weather data streams to develop the framework necessary to implement an operational space weather mission support infrastructure. There is heavy emphasis on the integration of various space weather models in a high performance computing system architecture to formulate the bases of real time operational tool supporting exploration class space missions.  New methods and techniques are investigated and developed in collaboration with academia and other NASA centers to capitalize on available assets, develop space weather forecasting capabilities, and operationally mitigate the adverse biological risks associated with space weather events.  The new team member should be versed in the physics and propagation characteristics of Coronal Mass Ejections through the heliosphere and working with large data sets to describe, analyze, and predict space weather phenomena.  A working knowledge of existing forecasting models with a focused transition from research to operations is emphasized.  Specific experience with the flare and solar energetic proton models housed at the Community Coordinated Modeling Center (CCMC) is desired.

Primary Duties & Responsibilities:

  • Responsible for compliance with Safety, Health and Environmental plan; must be committed to a high standard of safety and be willing and able to comply with all safety laws and all of the Company’s safety policies and rules and must be willing to report safety violations and potential safety violations to appropriate supervisory or management personnel.

  • Ability to work independently on complex problems and interfacing with a project.
  • Strong experience in analyzing large data sets
  • Solid experience with space weather forecasting models
  • Understanding of operational needs and relevancy of model outputs
  • Develop test and verify space weather forecasting models
  • Understand model performance through extensive model verification and validation
  • Ability to work within a dynamic team environment
  • Excellent skills in both written and verbal communication

Required Education and Experience:

  • This position requires a Bachelor’s Degree plus 4 years of experience; or Master’s Degree plus 2 years of experience (preferred) in either, physics, Nuclear engineering or a closely related field

  • Able to work effectively with minimal supervision
  • Work effectively in a team environment
  • Familiarity with standard programming languages and computer analysis tools (e.g., one or more of the followings -- FORTRAN, C++, MATLAB, LabView, Solidworks, CAD, Java, Python, IDL ETC.)

Desired Education and Experience:

  • A Bachelor's degree in the field of space physics, solar and space sciences, physics, or a calculus based physical science. A Master's degree or Ph.D.  in one of these disciplines is highly desirable
  • Knowledge of, space weather forecasting techniques/models, statistics, space sensor technologies, high performance computing systems and radiation data streams from various satelitte asetts as related to the space weather field
  • Ability to develop and manage independent research and development tasks in the space environments and effects discipline
