New ideas are all around us, but only a few will change the world. That’s our focus at JPL. We ask the biggest questions, then search the universe for answers—literally. We build upon ideas that have guided generations, 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’re driven to discover, create, and inspire something that lasts a lifetime and beyond, you’re ready for JPL.

Located in Pasadena, California, JPL has a 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.

You will work as a full-time scientist responsible for assimilating chemically reactive and carbon gases into state-of-the-art chemical transport models to quantify the evolution of atmospheric composition and the emissions that drive them.  You will work closely with science teams at JPL to better harness existing composition datasets from instruments such as AIRS and MLS, new multi-satellite products such as AIRS/OMI ozone, contribute to formulation studies of new mission concepts through Observing System Simulation Experiments (OSSE), and development of next-generation chemical transport models.   In addition, the scientist is expected to work in a dynamic team environment addressing cutting-edge challenges in air quality and climate with scientists working across multiple scales.  You will be expected to publish scientific findings in top-tiered peer-reviewed scientific journals as well as presenting results in the related science team meetings, workshops and conferences.


  • PhD in Atmospheric Science, Geophysics or a related technical discipline.
  • Demonstrated experience with satellite data assimilation of atmospheric chemical species in global chemical transport models.
  • Advanced knowledge of chemistry and transport models.
  • Excellent oral (including public speaking) and written communication skills.
  • Experience working in a team environment.
  • Strong interpersonal skills.
  • Peer-reviewed publications that demonstrate the areas of required experience mentioned above are necessary.

Preferred Qualifications:

  • Demonstrated skill in carbon cycle science, stratospheric chemistry, and/or air quality.
  • Advanced knowledge of data assimilation of satellite observations in global chemical transport models.
  • Experience with running the GEOS-Chem High Performance chemical transport model.
  • Ability to perform multi-constituent data assimilation using multiple satellites.
  • Familiarity with the use of chemical model fields in providing context for aircraft campaign measurements.

Complete applications will include a cover letter describing the applicant’s vision for their role at JPL in the field of Earth System Science, a curriculum vita including a bibliography of refereed publications and other work, a statement on research experience and research objectives, and contact information for three professional references.
