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 scienceandengineering organizationsandon Caltech’s academic campus often work together. Learning to speakandunderstand 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 scienceandtechnology. They are supported in developing ideas into proposalsand hardware,and in communicating funded missions’ results to the scientific communityand the broader public. JPL seeks to employ scientistsandengineers who are passionate about lifelong learningandexcited to both contribute toandlead team efforts. We emphasize the importance of partnering across discipline boundariesandcreating 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,andsocial connections across the JPLandCaltech community for advice on housing, childcare,andother aspects of living in southern California.

JPL’s Optics and Spectroscopy Section is seeking a postdoc who will advance coronagraphic mask design and modeling, conducting research that enables the direct imaging of earth-like exoplanets with the Habitable Worlds Observatory (HWO). The position offers opportunities to develop and validate vector diffraction models of coronagraphic optics, numerically optimize coronagraph masks, improve mask fabrication processes, run experiments on several coronagraph benches, and publish high-impact scientific results that advance the state of the art in high-contrast imaging.

Research Responsibilities

• Conduct independent research on vector diffraction modeling of various coronagraphic masks.
• Validate mask models with laboratory experiments on the High Contrast Imaging Testbed (HCIT) facility.
• Develop requirements on mask fabrication tolerances and materials required in the contrast budget for HWO.
• Perform coronagraphic mask optimization using algorithmic differentiation and other advanced methods.
• Utilize artificial intelligence tools to improve the mask design and modeling processes.
• Publish research findings in peer-reviewed journals and present results at national and international conferences.
• Collaborate with multidisciplinary teams spanning numerical optimization, optical design, optical modeling, microdevices fabrication, and coronagraph testbeds.

Required Qualifications

• Ph.D. in Optics, Astrophysics, Physics, Mechanical Engineering, Aerospace Engineering, or a closely related field.
• Experience in high-contrast imaging, optical modeling, optical instrumentation, wavefront correction, or related experimental research.
• Experience using finite-difference time-domain (FDTD) software packages such as MEEP or Lumerical.
• Experience using clusters and GPUs for large computational tasks.
• Proficiency in scientific programming using Python, MATLAB, or similar programming languages.
• Demonstrated record of peer-reviewed publications and excellent written and oral communication skills.

The appointee will carry out research in collaboration withJPL advisor,resulting in publications in the open literature.

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.
