Job SummaryIPAC at Caltech has an opening for an experienced Application Developer to manage the Data Systems development team at the NASA/IPAC Infrared Science Archive (IRSA). This is first and foremost a people-management and leadership role: you will supervise, mentor, and set priorities for a team of software developers, represent the team to stakeholders, and guide its technical direction, while the team builds the tools that let astronomers and data scientists all over the world access and explore IRSA's petabyte archives of astronomy data.
IPAC, part of the Physics, Math, and Astronomy Division at Caltech (www.caltech.edu), provides science operations, user support, data and archive services, and scientific vision to enhance discovery with observatories both in space and on the ground.
IRSA (http://irsa.ipac.caltech.edu) is the steward of scientific data sets delivered by NASA's Astrophysics missions. We enable ground-breaking scientific research using data from these and other missions. IRSA ingests petabyte-scale imaging datasets, maintains multi-billion row databases, and develops a variety of tools for accessing, visualizing, and analyzing data from cutting-edge astronomical facilities. Current missions include SPHEREx, a NASA mission which will conduct a spectroscopic, infrared survey of the entire sky; and Euclid, a European Space Agency (ESA) mission to study the geometry and nature of the dark Universe. We are also preparing to support upcoming astrophysics missions including NEO Surveyor, a mission designed to discover and characterize most of the potentially hazardous asteroids that are near the Earth.
Essential Job DutiesAs IRSA Data Systems Team Lead you will supervise a group of IRSA developers who share the overarching goal of supporting community science with archival IRSA and other NASA data sets, set direction on technical approach, and work with scientists and other stakeholders to interpret and implement project requirements.
