About The Position

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 IPAC at Caltech is looking for a developer for the RAPID pipeline team. As a part of the Physics, Math, and Astronomy Division at Caltech, IPAC ( www.ipac.caltech.edu ) provides science operations, user support, data and archive services, and scientific vision to maximize discovery with observatories both in space and on the ground. We are partners with NASA, NSF, JPL, and the international research community to advance exploration of our Universe. Over our three-decade history, we have provided a range of support for more than 20 astronomy missions, helping each to bring forth major advances in astrophysics and cosmology. As a member of our RAPID team, you will enable scientists to explore the dynamic sky-finding supernovae, other rare cataclysmic events, variable stars, asteroids, and all other manner of time-varying phenomena from our solar system to the edges of the Universe. Where You Fit In RAPID is a time-domain Project Infrastructure Team (PIT) for the upcoming NASA Nancy Grace Roman Space Telescope. The PIT is responsible for a low-latency pipeline to discover changes between observations, then alert astronomers for follow-up with other resources. The pipeline will run within AWS, automatically processing observations on receipt, all without a human in the loop. The PIT will also provide associated resources and services to the international community, such as historical light-curves of variable sources and an on-demand forced-photometry service. The developer will help write, validate, and tune the pipeline and services, working with scientists and engineers across several Roman teams.
