Job Category: Fulltime Term Exempt Overtime Eligible: Exempt Benefits Eligible: Benefit Based
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.
Job Summary 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.
Job Duties - Verify optical focus and alignment at cryogenic operating temperature - Characterize instrument parameters such as spectral response, detector noise, flat field and image persistence - Characterize instrument components including 2k x 2k HgCdTe detector arrays - Qualify flight hardware under environmental thermal cycle and vibration - Design and procure laboratory calibration equipment including infrared collimators, monochromators, and cryogenic vacuum chambers to support these tests - Develop specialized control software to interface laboratory equipment with data acquisition systems for automating measurements - Document test results of flight hardware
Basic Qualifications - Undergraduate degree in engineering, physics or astronomy, with a minimum of 5 years of experience - A track record of successfully designing, building and testing cryogenic infrared instrumentation, as indicated
Preferred Qualifications - Graduate degree in engineering, physics or astronomy - US citizenship or permanent resident to facilitate access to NASA and aerospace facilities - Familiarity with instrument design software such as Zemax, Solidworks, Matlab, IDL, Python, etc. - Previous experience with flight hardware - Candidates with backgrounds in CMB/millimeter-wave instrumentation are also encouraged to apply.
Required Documents - Resume - CV - Cover Letter - 3 Letters of Recommendation
