Job Summary
IPAC at Caltech is seeking a Network Engineer to support the design, optimization, and operation of the high-performance network infrastructure powering world-class NASA, NSF, and privately funded ground and spaceborne observatories. As a member of the IPAC Support Group (ISG) Data Center Engineering team, you will work alongside other network, systems, and database engineers to build and maintain the vital pipelines that connect the global astronomical community to invaluable scientific data.
IPAC, situated within the Division of Physics, Mathematics, and Astronomy at Caltech (www.caltech.edu), provides science operations, pipeline processing, user support, and data services for high-profile missions including the Nancy Grace Roman Space Telescope, SPHEREx, Euclid, the Near-Earth Object Surveyor, and the Zwicky Transient Facility (ZTF). Our diverse portfolio of research archives includes multi-petabyte datasets like the NASA/IPAC Infrared Science Archive (IRSA), alongside highly curated reference repositories like the NASA Extragalactic Database (NED) and the NASA Exoplanet Archive, which are key research references for modern astrophysics and exoplanet science.
This role offers a rare combination of mission-driven work, technical variety, and collaborative engineering. As part of a close-knit team of about ten engineers, you will have broad visibility across IPAC's infrastructure, contribute directly to project architecture and design, and advance the technologies that support IPAC's scientific mission.
