Job Description:

Science Systems and Applications, Inc. (SSAI) is seeking a Senior Scientist/Engineer with experience in space sensors and instrument calibration to support projects on the Hydrosphere, Biosphere and Geophysics (HBG) contract at NASA's Goddard Space Flight Center. 

If you are on a journey to explore and expand your ideas and career, you are ready for HBG. This contract provides scientific, engineering and software support for the design, development and testing of remote sensors, sensor systems, space-based instruments, sensor calibration and on-orbit performance analysis to NASA. Check out more information on the NASA website here.

At SSAI we invest in our people, optimize creativity and leverage opportunities. At SSAI, we provide robust training opportunities and mentoring to advance your career, giving new opportunities when possible to switch teams and projects as the company grows and evolves. Our collaborative team environment encourages employees to be enthusiastic, creative and to bring challenging ideas that enhance your passion for science and technology while maintaining work-life balance. If this is what you are looking for, we want to hear from you.

Situated at GSFC, Greenbelt, MD, this position will support the calibration and validation of optical Earth imaging sensors onboard current and upcoming NASA missions such as the new future generation of Earth sensors, the Climate Absolute Refractivity and Reflectance Observatory (CLARREO) Pathfinder (CPF) mission. The work being developed demonstrates SI-traceable retrievals of the reflectance at unprecedented accuracies for global satellite observations, and involves the use of state-of-the-art technologies such as the NIST-calibrated transfer radiometers to assess the spectral radiance from a NASA laser source with a very good accuracy. The work also involves measurements from ground, airborne and space based remote sensing instruments to monitor and independently assess instrument calibration performance, develop and utilize software for processing the data from instrument systems and related ancillary data sources to validate and improve spectral bands calibration algorithms. The work involves frequent interactions with the scientific user community to investigate instrument calibration and performance issues.

Required Qualifications:
  • MSc. or higher degree in physics, engineering or comparable field of study and at least 5 years of related experience
  • Demonstrated experience with analysis software such as IDL, and Python
  • Strong background in data analytics, and able to identify and perform research tasks
  • Capable of working both independently and within a dynamic science team
  • Excellent verbal and written communication skills are a must, as demonstrated by peer-reviewed publications and oral presentations made at major science conferences
  • US Citizenship or Permanent Residency required
Desired Qualifications:
  • Experience working with space sensors testing, calibration and characterization
  • Experience with Machine Learning algorithm in support of data processing and science data products retrievals.
