Job Snapshot

Job Description

The Pipeline Scientist is primarily responsible for ensuring the smooth transfer of SOFIA raw and pipeline processed data from the archive at the Science Mission Operations (SMO) center at Ames to the NASA/IPAC Infrared Science Archive (IRSA). IRSA will become the permanent archive for SOFIA data for the astronomical community.  This effort will involve identifying and packaging data files, staging and transferring the data, gathering and revising documentation, revising file headers, reformatting and reprocessing data when necessary, and verification and validation of various aspects of the archive and the retrieval system at IRSA.

In addition, the pipeline scientist will be responsible for some amount of data processing and assessing the quality of the data obtained by facility science instruments on board the Stratospheric Observatory for Infrared Astronomy (SOFIA). After processing the data files, the Pipeline Scientist examines the data products generated by the pipelines to ensure that they are suitable for distribution to General Observers. The Pipeline Scientist documents the quality assurance assessment, derives calibration factors, applies the factors to the reduced data, ingests the calibrated data into the archive, and notifies observers that the data are available for downloading.

The Pipeline Scientist will have up to 20% of their time available for scientific research, preferably on topics relevant to SOFIA and its scientific mission. A demonstrated history of active research and research interests broadly related to SOFIA science will have a particular advantage.

This position is a 2-year appointment, with a third year possible depending on performance and funding.

Essential Duties/Responsibilities:

  • Perform tasks related to the transfer of raw and reduced data from the SMO to IRSA.
  • Revise documentation regarding data products and deliver to IRSA.
  • Reformat pipeline processed data for successful ingestion by IRSA as needed.
  • Revise and update file headers when necessary for successful IRSA ingestion.
  • Perform Verification and Validation tasks on archival system developed by IRSA for SOFIA data.
  • Inspect the product tree generated by automated pipelines, and run the data processing tools manually when necessary.
  • Identify data/instrumental artifacts and carry out corrective measure to mitigate them (e.g., identify and exclude low-quality data from subsequent pipeline processing)
  • Analyze products of the data processing from science observations to ensure the results are valid and not impacted by artifacts; document quality inspection results.
  • Compare observations of calibration sources to model calculations to derive calibration factors; document quality of calibration; apply to the associated science observations.
  • Verify the quality of calibration observations and the calibration products
  • Generate documentation for each observation with disposition status and other relevant notes.
  • Release files that are nominal / useable for the archive.
  • Perform independent research in a field aligned with SOFIA
  • Engage the scientific community in research work through research collaborations, visits, invited guests, workshops, conferences, etc.
