Science Systems and Applications, Inc. (SSAI) is seeking a Senior Microwave Satellite Earth Scientist. This scientist will provide support for the development of new microwave-based Earth-observing satellite instruments. Roles and Responsibilities: + Download and process raw satellite data. + Participate in activities related to detection of Radio Frequency Interference (RFI) in microwave observations and support the calibration of microwave instrumentation. + Support instrument testing and instrument performance test verification. + Write code to create or adapt models for microwave remote sensing; adapt existing computer models from one programming language to another; run the code; generate plots, tables, and images from the model output; automate some of these tasks; assist with data interpretation. Document code, algorithms, procedures, and results. + Support the generation of manuscripts, presentations, reports, and proposals. This includes helping with the production of images, figures, tables, and charts. + Make presentations at project reviews or technical conferences as requested. + Participate in teleconferences, videoconferences, and in-person meetings as needed to support project activities. + Document discussions, action items, decisions, and questions as needed. Organize these records with related records, including any hardcopies and/or uploading of such documentation to appropriate websites, and organizing of information on those websites. + Provide programming support, mostly in Matlab. + Ensure backup copies of electronic records are current. Required Qualifications: + PhD in an Earth Science, Engineering, or Environmental Science discipline using satellite observations. + Ability to travel to support field calibration activities. + Comply with NASA & GSFC rules regarding IT security, proper use, as well as ITAR and EAR export control regulations. The candidate’s citizenship or visa status must allow unrestricted access to export-controlled information. + Expertise in Matlab is required. + Knowledge of microwave radiometers and associated calibration techniques, microwave atmospheric sounding techniques, satellite geolocation and simulation. + 10+ years of experience with active and passive microwave remote sensing, microwave radiometer ground and on-orbit calibration, satellite geolocation, and ground calibration processing system development Desired Qualifications: + Experience with software testing and debugging; collecting test requirements, composing tests plans, and tracking performance against test cases. + The candidate should have the ability to collaborate within a team environment and have the ability to work independently to deliver individual contributions. + Knowledge of programming languages other than Matlab, experience working with Google Earth, and/or GIS software would be desirable but not required. Operating systems may include Linux/Unix, real time Unix, Mac OS and Windows. + Experience with JPSS calibration/validation desired.
