What You Will Do:

  • Monitor and report quality of daily spectroscopic data processing.

  • Maintain and improve spectroscopic pipeline algorithms in response to issues discovered in data and by science analyses.

  • Interact with DESI collaboration science working groups to assist them with using the DESI data and improve the data processing algorithms in response to the needs of the science analyses.

  • Coordinate with the survey team to schedule calibrations and observations based upon data quality.

  • Coordinate regular DESI software releases for reprocessing runs, including testing and documentation.

  • Contribute to the operations of the spectroscopic pipeline at NERSC, both the daily runs and the reprocessing for the data assemblies.
