NASA, the world's leader in space and aeronautics is always seeking outstanding scientists, engineers, and other talented professionals to carry forward the great discovery process that its mission demands. Creativity. Ambition. Teamwork. A sense of daring. And a probing mind. That's what it takes to join NASA, one of the best places to work in the Federal Government.
The Science & Exploration Directorate, Earth Sciences Division, Terrestrial Information Systems Lab (Code 619) is seeking a scientist to provide expertise in the quality assessment of global land science products. In this role you will serve as the Quality Assessment lead for products produced by data systems supporting the Terra, Aqua, and Suomi NPP missions.
Please be sure to review your resume on the Resume Review page once you have transferred to the NASA site. Ensure that the correct copy of the resume you have selected has been transferred from your USAJOBS account. If you fail to validate the information in your resume, you may not be appropriately evaluated for this position. Also, please be sure to review and complete the Supplemental Information questions.
To receive consideration, you must submit a resume and answer NASA-specific questions. The NASA questions appear after you submit your resume and are transferred to the NASA web site. If you successfully apply, USAJOBS will show your application status as 'resume received - complete.' If your status is 'Application Started,' you have not successfully applied. Do not rely on a USAJOBS email to confirm successful application only an email from NASA confirms a successful application.
To receive consideration, your resume MUST contain your complete degree information (i.e., type of degree received, year degree received, and major area of study). If you have received a degree in Computer Science, you MUST list all courses you have taken which meet the education requirements as stated in the qualification requirements section as well as the semester hours awarded. You MUST include the descriptive title, course code, and number of semester/quarter hours. (i.e., CMSC-435-Software Engineering, 3 Semester hours) If this information is not provided, your education may not be appropriately evaluated and you may lose consideration for this position. Please note that degrees in engineering technology are not considered to be qualifying for this position. If you are selected for this position, you will have to provide an official copy of your transcripts prior to entering on duty.

As an Aerospace Technologist (AST) specializing in Applications Data Management, you will provide technical leadership to a team of remote sensing analysts and software developers engaged in assessing the quality of global products produced from data collected by moderate-resolution earth imaging satellite instruments, e.g. AVHRR, MODIS and VIIRS. This activity includes developing strategies, formulating requirements and defining priorities for quality assessment and long-term trending of the products. You will lead the development and refinement of procedures and tools for displaying, transforming and evaluating the accuracy of global land products. This includes determining the accuracy, precision and stability of geophysical products over the life of each mission; and developing improvements to product specific metadata. You will collaborate with other remote sensing scientists to address issues with geolocation, calibration, atmospheric correction and cloud screening in order to develop and implement corrections needed to achieve a stable, accurate and consistently processed data record from a variety of data sources. You will explore and define state-of-the-art solutions to address the needs of many diverse groups of scientists and applications users in the quality assessment of global data products, and publish, or contribute to publications, as appropriate.
Responsibilities also include designing, developing and managing the operation of data systems used to evaluate and/or produce large data sets from ground and satellite-based instruments. Activities include: developing and/or reviewing designs for meeting current and future requirements, evaluating enhancements to existing systems and software prior to these changes being promoted to operations, and managing the operations of quality assessment and/or product generation systems. In addition, you will design and oversee the development and maintenance of global science product quality assessment tools to be used by instrument quality assessment teams, instrument science teams and researchers in the science community. The tools will incorporate state-of-the-art algorithms for transforming and analyzing data products in applications that can be easily mastered by researchers and the applications community.
As QA lead, you will plan, manage and coordinate efforts for large-scale science tests leading up to reprocessing campaigns for the entire data record for earth observing satellite instruments. This will include working closely with instrument science team principal investigators and science support team leaders to develop and maintain schedules; developing and reviewing plans for large-scale tests of science software used in the generation of global products; and analyzing the products generated during these tests and providing written recommendations on test findings.
