Job Summary

IPAC at Caltech has an opening for a scientist to participate in the Euclid and Roman missions by joining the user support teams. IPAC is part of the Physics, Math, and Astronomy Division at Caltech (www.caltech.edu) and provides science operations, user support, data and archive services, and scientific vision to maximize discovery with observatories both in space and on the ground.

Roman: The Nancy Grace Roman Space Telescope is a NASA observatory designed to address key questions in the areas of dark energy, exoplanets, and infrared astrophysics. It is slated for launch in Fall 2026. The Roman Science Support Center (SSC) at IPAC is a part of the Roman Ground Data System, providing algorithm and software development for spectroscopic and Galactic Bulge Time Domain Survey data processing. In addition, the SSC will support the operations of the Coronagraph Instrument, manage the Roman guest investigator proposal solicitations, and provide community support for exoplanet and wide-field spectroscopy science with Roman.

Euclid: Euclid is a European Space Agency (ESA) mission, launched in 2023, to study the geometry and nature of the dark Universe. NASA established the Euclid NASA Science Center at IPAC (ENSCI) in order to support US-based investigations using Euclid data. ENSCI participates in the Euclid Consortium's Science Ground Segment, providing algorithm and software development, participating in data quality assurance, and performing data processing. In addition, ENSCI supports the US research community by providing expert insight into the Euclid surveys, data processing, calibration, and data products.
