The Deep Synoptic Array (DSA) is a next-generation radio telescope being developed for deployment in a radio-quiet valley in Nevada. Comprising 1,650 dishes, the DSA is designed to survey the sky at unprecedented speed and sensitivity. During its five-year initial survey, the DSA is expected to detect more than one billion astronomical sources, produce images and transient alerts in real time, and rapidly deliver science-ready data products to the astronomical community. The DSA brings together scientists, engineers, technical experts, and project professionals across a large, multidisciplinary collaboration. As the project advances toward construction and operations, the DSA offers an opportunity to contribute to the development and delivery of a major new facility at the forefront of radio astronomy.
