Job Summary

As a part of the Physics, Math, and Astronomy Division at Caltech, the NASA Exoplanet Science Institute (NExScI; nexsci.caltech.edu) provides science operations, analysis tools and archive services related to the discovery and characterization of planets beyond our solar system (exoplanets) using data from observatories in space and on the ground. NExScI operates as part of IPAC on the Caltech campus ( www.ipac.caltech.edu) which provides support for NASA's NEOWISE mission, 6 other NASA missions in development, more than half of NASA’s astronomy archives as well as ground-based observatories like the Zwicky Transient Facility. Together IPAC and NExScI have supported more than 20 astronomy missions, including Spitzer, Kepler, TESS and the 10 m Keck telescopes, which have contributed to major advances in exoplanet science, astrophysics and cosmology.

The Keck Observatory Archive (KOA) is a collaboration between NExScI and the W. M. Keck Observatory in Hawaii. It archives at NExScI all data acquired by the 10-m telescopes at the W. M. Keck Observatory and makes them available through web interfaces and a Python API. KOA is undergoing an exciting and dramatic expansion. Data acquired each night are now ingested close to near-real time, and science ready processing of these data are ingested no more than 24 hours later. In support of this expansion, KOA is developing a new Python-based software infrastructure and new outward facing web page.  Real-time ingestion prepares KOA for the scientific analysis of the torrent of transient alerts that will be generated by the next generation of survey telescopes, such as the Rubin Observatory. This will offer, to a scientific programmer, extraordinary opportunities to develop powerful new services that will be at the forefront of astronomical research. In the coming years, unique new instruments at the observatory will offer further opportunities for advanced  services, particularly those that involve cross-matching and fusion of data from multiple sources. As a member of the NExScI engineering team, you will be working to enable scientists to make exciting discoveries in diverse fields, from our Solar System to the distant regions of the Universe.  New science applications are anticipated to comply with the data access standards defined by the International Virtual Observatory Alliance (IVOA), which are now in worldwide use in astronomy, and will be made Open Source.

Job Duties

  • Work with the KOA team, especially scientists, to define and implement public-facing science applications
  • These applications will often involve accessing astronomy data at remote archives and combining them with KOA data
  • Support the development of the archive query infrastructure
  • Support the maintenance and operations of the archive
  • Respond to technical questions from users, where appropriate
