Description

Job Description:

The Space Radiation Analysis Group at NASA's Johnson Space Center is seeking subject matter expertise in radiation measurements and instrumentation including hybrid pixel detector technologies as developed through collaborations with CERN and academia, solid-state detectors, gas filled detectors and scintillation detectors. The successful applicant will produce analytical products based on data collected from existing and future instrument measurements.  Additionally, the applicant will use these analysis products to characterize several aspects of the charged particle environment in space. Applicants must be accomplished in various radiation measurement concepts, practices and procedures with proven ability to solve complex system level problems. Duties will include the development, maintenance, and improvement of codes and models used to characterize the space radiation environment and human exposure in that environment. Both static and transient environmental models are used to describe types and energies of radiation found in space. Extensive experience in calibration and instrument performance verification and validation is essential. Subsequent analyses to fully understand and optimize performance measurements is required. A comprehensive understanding of particle ID and binning algorithms will be necessary. Ability to work well in a team environment with other scientists, engineers, software developers, and operations personnel on high profile milestone driven projects is critical. Participation with technical teams to develop test plans, calibrate instruments and conduct verification and validation beam campaigns at various beam facilities is required.

The subject matter expert will be:

  • 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.
  • Responsible for compliance with the Quality Assurance Plan, policies and procedures
  • Perform astronaut radiation exposure analysis for ISS and Artemis missions.
  • Compare measurement data from space based radiation detectors with modeled results.  
  • Perform comparative analyses of various environmental and radiation transport models and methods for calculating astronaut radiation exposures for various design reference missions
  • Familiar with space radiation detection instrumentation and state of the art technologies.

Required Education and Experience:

  • Bachelor’s Degree plus 15 years of experience; or Master’s Degree plus 10 years of experience; or Ph.D. plus 5 years of experience (preferred) in either, physics, Nuclear engineering,  or a closely related field with experience in radiation measurements.
  • Intimate knowledge of radiation measurements in space is highly desired.
  • Strong programming and MonteCarlo simulation skills
  • Sound fundamentals and experience in Hybrid Pixel radiation detector technology.
  • Sound fundamentals in programming and computational problem solving are required along with expertise in radiation transport (deterministic and Monte Carlo) techniques and radiation exposure assessments.      
  • Charged Particle and Neutron Spectroscopy
  • Software and hardware integration
  • Silicone detector simulations
  • Beam testing and data analyses
  • Energy identification
  • Experience developing and implementing operational strategies with focus on meeting long-term goals

Desired Skills:

  • Preference given to applicants with advanced graduate degree in physics

  • A comprehensive working knowledge of radiation exposure risk assements and NCRP, ICRP, BEIR, and UNSCEAR guidelines and methodologies.

  • Experience using Analytica, Zotero, and Confluence is highly desired.
  • 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.)

This position requires successful completion of a government background check to access government facilities and/or systems. If you are not a U.S. Citizen or U.S. Permanent Resident, the background investigation could take 12-18 months to complete.
