Caltech is a world-renowned science and engineering institute that marshals some of the world's brightest minds and most innovative tools to address fundamental scientific questions. We thrive on finding and cultivating talented people who are passionate about what they do. Join us and be a part of the diverse Caltech community.
The Observational Cosmology group at Caltech is looking to hire an outstanding candidate to work on the integration, test and characterization of the SPHEREx flight instrument. SPHEREx is a new infrared survey satellite, recently selected by NASA as a medium-class explorer satellite for launch in 2023.
SPHEREx will map the large scale structure of galaxies to probe cosmological parameters, including signatures from the period of inflation. It will also study galaxy evolution, survey biogenic ices during the early phases of star formation throughout the Milky Way, and produce a large spectral dataset for the astronomical community. The selected applicants will develop, test and characterize the telescope, filter and detector system to meet flight requirements to achieve these goals.
