Senior Hyperspectral Microwave Instrument Scientist

Job Description

Science Systems and Applications, Inc. (SSAI) is seeking a Senior Hyperspectral Microwave Instrument Scientist on an as-needed basis to support the development of next-generation hyperspectral microwave-based Earth-observing satellite instruments. This scientist will contribute to instrument concept development, radiative transfer modeling, retrieval system integration, and calibration/validation studies. This is not a full-time role.

In this role you will be responsible for the following:

Conduct simulations to inform the design of a hyperspectral microwave instrument.

Perform in-depth analysis of microwave radiative transfer for atmospheric sounding.

Compare performance of conventional microwave sounders (e.g., ATMS) versus hyperspectral systems.

Support radiative transfer model development, satellite radiance assimilation, and calibration of microwave sensors.

Analyze and process raw satellite data for instrument performance and scientific analysis.

Write and maintain scientific code (primarily Python) for simulation, modeling, and data analysis.

Generate plots, tables, and images from model and retrieval outputs; automate key workflows where possible.

Document code, algorithms, simulation procedures, and scientific findings.

Collaborate in the preparation of scientific publications, presentations, technical reports, and proposals.

Present results at technical conferences and project reviews.

Participate in virtual and in-person project meetings; document outcomes, decisions, and action items.

Support calibration and validation activities, including field campaign planning and analysis.

Maintain organized and backed-up electronic records and documentation.

Required Qualifications:

Ph.D. in Atmospheric Science, Physics, Electrical Engineering, Remote Sensing, or a related field.

10+ years of experience in microwave remote sensing, including both passive and active systems.

Direct experience with the Microwave Integrated Retrieval System (MIRS).

Expertise in microwave radiative transfer and atmospheric sounding techniques.

Familiarity with satellite radiance assimilation and microwave sounder instruments (e.g., ATMS).

Proficiency in scientific programming (Matlab required; Python a plus).

Experience with calibration techniques for microwave radiometers and sounders.

Strong quantitative skills, including advanced knowledge of atmospheric physics.

U.S. citizenship or permanent resident able to work with export-controlled data per ITAR/EAR requirements.

Desired Qualifications:

Experience with software testing, debugging, and version control.

Ability to work independently while also collaborating effectively within a multidisciplinary team.

Experience with JPSS satellite systems, including ATMS and calibration/validation processes.

Knowledge of additional programming languages (e.g., Fortran, C++) or geospatial tools (e.g., Google Earth, GIS software).

Experience working in Linux/Unix environments and handling satellite data formats.

Physical Requirements: While performing the duties of this job, the employee is occasionally required to stand; have mobility; sit; use hands to finger, handle, or feel; reach with hands and arms; stoop, kneel, crouch, or crawl and talk or hear. The employee may occasionally lift and/or move up to 10 pounds.
