Job Details

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.

JPL is unique among NASA Centers in that its staff are Caltech employees, yet can access NASA technical resources. Cross-discipline teamwork is standard here: colleagues across JPL's science and engineering organizations and on Caltech's academic campus often work together. Learning to speak and understand other disciplines' languages is a doorway to the creativity needed to do what has not been done before. JPL staff are encouraged to create mission concepts that address humanity's core questions through a combination of science and technology. They are supported in developing ideas into proposals and hardware, and in communicating funded missions' results to the scientific community and the broader public. JPL seeks to employ scientists and engineers who are passionate about lifelong learning and excited to both contribute to and lead team efforts. We emphasize the importance of partnering across discipline boundaries and creating a friendly, constructive work environment to overcome space exploration's challenges. The Postdoctoral scholars at JPL benefit from an informal mentoring network, an annual conference showcasing their results, a dedicated seminar series, exposure to diverse career paths, and social connections across the JPL and Caltech community for advice on housing, childcare, and other aspects of living in southern California.

The Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals (SHERLOC) instrument is an arm-mounted Raman and fluorescence mapping spectrometer with context imagers on the Mars 2020 Perseverance rover, designed to characterize organics and minerals on the surface of Mars. SHERLOC is a deep UV (DUV) (248.6 nm incident laser) Raman spectrometer with two context imagers: the Autofocus and Context Imager (ACI) - a 10.1 μm/pixel monochromatic camera - and the Wide Angle Topographic Sensor for Operations and eNgineering (WATSON) camera, which is a copy of the Mars Science Laboratory (MSL) Mars Hand Lens Imager (MAHLI) camera, capable of acquiring images focused at infinity to microscopic scales (13 μm/pixel). SHERLOC collects hyperspectral maps up to 7x7 mm in size that are co-registered to context images for comparison with morphologic features.

Since landing on the surface, SHERLOC has detected a variety of mineral species, including aqueously altered igneous minerals, phosphates, sulfates, chlorine-bearing minerals, carbonates, and potentially the presence of organics.

The SHERLOC investigation on the Mars 2020 Perseverance rover mission seeks qualified postdoc applicants, to be based at JPL, working as part of the SHERLOC team on the following research tasks:

  • Participate in mission operations, specifically those associated with operations of the SHERLOC instrument on Mars.
  • Laboratory studies of Mars analog mineral and organic samples, with specific application to interpretation of SHERLOC spectroscopy data from Mars.
  • Hyperspectral visualization and analysis software development.
  • Assist with flight system test bed activities.
  • Conduct and lead original research based on SHERLOC data, and publish manuscripts reporting results.

Required Qualifications:

  • PhD in planetary science, engineering, or related discipline.
  • Programming experience in Python or related programming languages.
  • Hands on laboratory experience, ideally with spectrometers and instrumentation.
  • Proven record of leadership on peer-reviewed scientific publications.

Applicants may be subject to additional program requirements by NASA. Postdoc positions are awarded for a minimum of one-year period and may be renewed up to a maximum of three years. Candidates should submit the following to this site: CV, representative publications, contact information for three references, and a cover letter stating their research accomplishments and interests.

JPL has a catalog of benefits and perks that span from the traditional to the unique. This includes a variety of health, dental, vision, wellbeing, and retirement plans, paid time off, learning, rideshare, childcare, flexible schedule, parental leave and many more. Our focus is on work-life balance, and living healthy, fulfilling lives as we Dare Mighty Things Together.
