The Smithsonian Astrophysical Observatory (SAO) invites applications from highly qualified individuals for at least two permanent-track research astronomer openings, with potentially as many as four openings depending on funding availability and candidate qualifications. These positions are analogous to a tenure-track assistant professorship. To leverage next-generation telescopes and research opportunities, the SAO priority areas for hiring this year are in time-domain astronomy, extrasolar planets, Earth observing, and instrumentation development for new ground and space facilities.
