Within this Section, the Planetary Mass Spectrometer Group seeks a self-motivated individual who can work well independently and in a team environment. The selected candidate will have the opportunity to contribute in both ground-based and space-based research for general mass spectroscopy in combination with geochemistry, isotope geochemistry, chromatography, cosmochemistry, absorption/emission spectroscopy, and astrobiology as an in-situ Mass Spectrometer Technologist level 2 in the following ways:

  • To work on technology development tasks such as the Spacecraft Atmosphere Monitor (S.A.M) instrument, which is used on board the International Space Station.
  • Be responsible for performing calibration and instrument development within the areas of mass spectroscopy, gas chromatography, with a strong focus on operation and data analyses.
  • To be the lead on new technology infusions for novel instrumentation applied to future planetary and human exploration.
  • Such as instruments to the Lunar surface or atmosphere of Venus.
  • Writes and contributed to proposals to obtain funding for future technology developments.
  • To create and fulfill opportunities to design, develop, document, implement, and verify new technologies for mass spectrometer instruments from the breadboard throughout the flight implementation phase.
  • To identify new scientific questions and issues, apply theoretical principles, and use creative analytical, experimental techniques, and scientific methods to develop new technology and instrument opportunities.
  • To establish and verify models of instrument properties in support of design, calibration, and performance verification.
  • Works independently on high visibility assignments and projects with only limited supervision, typically receiving only general instructions.
  • Exercises discretion and independent judgment to compare and evaluate various methods, approaches, resources and decide which will best accomplish each aspect of such assignments with the agreement of the project management.

Required Skills:

  • Must be a US Citizen or Green Card Holder
  • Strong interest working from conception through flight delivery, for mass spectroscopy, chromatography, fields and charged particles projects.
  • Bachelor’s degree in atomic and molecular physics, analytical chemistry or related technical disciplines with 5 years of related experience; or Master’s degree in similar disciplines with 3 years of related experience; or PhD in related fields.
  • Advanced knowledge and demonstration of instrument building skills in one or more of the following areas: charged particle optics, mass spectroscopy, atomic and molecular physics, gas and/or liquid chromatography, absorption/emission spectroscopy, or microfabrication techniques.
  • Extensive understanding and wide application of principles, theories, concepts, and techniques into instrument design principles.
  • Requires experience with hands-on and understanding of all mass spectrometer instrument related subsystems, e.x., vacuum systems and their components, RF and high voltage electronics circuits, control software, and data extraction.
  • Demonstrated how to design, fabricate, build, test, calibrate, and evaluate fully operational mass spectrometer systems.
  • Knowledge on how to derive science requirements and their implementation and verification.
