Scientist II, Planetary Chemistry and Astrobiology Group - NASA

Pasadena, California

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 be a member of the Planetary Science Section (322) and will report to the Group Supervisor of the Planetary Chemistry and Astrobiology Group (3225). Will be responsible for the following:

  • Support the PIXL Instrument Investigation on NASA’s Mars 2020 Rover mission (http://mars.nasa.gov/mars2020/mission/instruments/ ). PIXL will use micro-X-ray fluorescence spectrometry to measure the chemistry of rocks and soils targeted by the 2020 Rover, providing sub-millimeter resolution of geochemical variations correlated with rock texture and structure.
  • Work under the guidance of the PIXL Principal Investigator to provide support for instrument development, testing, calibration, operations planning and related scientific problems.
  • Support PIXL Phase E operations, including experiment planning, data analysis and science interpretation.
  • Responsible for publication of science results both from the Mars 2020 mission.
  • Build your own independent research and conduct your own science research in areas relevant to PIXL, Mars 2020, potential Mars Sample Return and ancient biosignatures by proposing to internal JPL and external funding opportunities.



  • PhD degree in Astrobiology, Geology or related scientific or technical discipline.
  • Demonstrated working knowledge at the forefront of biosignature detection and paleoenvironmental analysis.
  • Experience with micro-XRF, petrology and related sample analysis techniques.
  • Peer-reviewed publications in this field.
  • Understanding of the principles and techniques of paleobiology and field astrobiology.
  • Experience in using micro-XRF data for geological and astrobiological investigations.


Preferred Qualifications

  • Experience with Early terrestrial biosignatures.
  • Familiar with XRF instrumentation (operation, design, data processing).
