The Giant Magellan Telescope is the most powerful ground-based telescope ever engineered. It was designed to push the boundaries of human knowledge and discover the unknown. With unmatched image quality, seven of the world’s largest mirrors will launch our view into the universe to uncover the cosmic mysteries of dark matter, investigate the origins of chemical elements, and search for signs of life on distant exoplanets for the first time.

The 30-meter class telescope is under construction at Las Campanas Observatory in Chile’s Atacama Desert, one of the best locations on Earth to view the heavens. From this unrivaled vantage into the southern sky, the Giant Magellan Telescope will produce the sharpest and most detailed images ever taken of our universe.

When complete in the early 2030s, the Giant Magellan Telescope will be the largest public-private funded science project in history. The endeavor was founded by an international consortium of 14 research institutions representing Australia, Brazil, Chile, Israel, South Korea, Taiwan, and the United States, and is managed by the GMTO Corporation, a 501(c)(3) nonprofit organization based in Pasadena, California. Our culture is impactful, inclusive, and fearlessly innovative. We solve the most difficult engineering challenges and scientific questions with talented individuals who share a passion for revolutionizing humanity’s knowledge of the universe.

We invite you to join our team and leave your mark on astronomy’s future and beyond.
