Signal Analysis Engineer II
New ideas are all around us, but only a few will change the world. That’s our focus at the Jet Propulsion Laboratory (JPL). We ask the biggest questions and then search the universe for answers. We build upon ideas that have guided generations and then share our discoveries to inspire generations to come. Your mission - your opportunity - is to seek out the answers that bring us one-step closer. If you are driven to discover, create, and inspire something that lasts a lifetime and beyond, you may be ready for the JPL.
JPL is a world leader in robotic space exploration, earth sciences and the development of life changing technologies located in Pasadena, California. JPL has a casual, campus-like environment situated on 177 acres in the foothills of the San Gabriel Mountains and offers a work environment unlike any other: we inspire passion, foster innovation, build collaboration, and reward excellence.
The Radar and Science Engineering Section in the Communications, Tracking, and Radar Division conducts research, development, and flight missions in the field of airborne and spaceborne remote sensing radar for NASA and other government agencies. This section specializes in systems and techniques related to synthetic aperture radar (SAR) imaging, radar interferometry, altimetry, Earth and planetary subsurface sounders, scatterometry, and cloud and precipitation radars. The section is also a leader in the area of planetary landing radars. Our radar program focuses on Earth and planetary science missions, with emphasis on first-of-a-kind radar systems and cutting-edge technology.
We are looking for an engineer to join the Algorithm Development Team (ADT) on the Surface Water and Ocean Topography (SWOT) project. SWOT is a groundbreaking mission that will collect interferometric synthetic aperture radar (InSAR) data from space to make measurements of water surface heights on Earth with a revolutionary combination of centimeter-scale vertical precision, fine horizontal resolution, and global coverage. Life on Earth depends on water, and these height maps will enhance our understanding of our home planet by answering important scientific questions in the areas of physical oceanography and inland hydrology.
The SWOT ADT is responsible for developing and implementing the advanced algorithms that will process SWOT data into high-resolution radar images and interferograms of the Earth surface, derive water surface heights from the interferometric phase, detect water features, fuse external geophysical information with the data, and produce data products tailored to the needs of oceanographers and hydrologists. ADT engineers design, code, and test the ground software that will create the science data products to be disseminated around the world.
We are looking for an engineer who is up to the challenge of developing algorithms and software that can meet the unprecedented needs of the SWOT mission.
- Design, implement, test, and validate algorithms and ground processing software that will produce SWOT data products to be distributed to science users and the public
- Algorithms may include: InSAR height estimation; phase bias correction of onboard InSAR processor; SAR/InSAR calibration, validation, quality assurance tools; atmospheric and ionospheric corrections; and retrieval of geophysical parameters from InSAR data.
- Develop simulation tools to support the development and validation of the SWOT algorithms and software.
- Work collaboratively with other engineers in an international team to develop, test, and deliver complex algorithms and software systems
- Understand and apply principles, theories, concepts, and techniques in radar processing and software development
- Communicate results to other project elements and the scientific community
- Bachelor's degree in Electrical Engineering, Geophysics, Computer Science with a minimum of 3 years of related experience; or Master's degree in similar discipline with 1 year of related experience including work done while getting their Master’s; or PhD with 0 years of experience in similar disciplines.
- Experience with interferometric SAR design and/or algorithm development.
- Data analysis and computer programming skills
- Strong communication skills.
- Ability to work well in a team environment.
- Experience collaboratively developing and delivering software products
- Expertise with both Python and C++
- Hands-on radar calibration and operational processing experience
