Communications and External Affairs Manager

The Giant Magellan Telescope is one of the most powerful ground-based telescopes ever engineered. It is designed to push the boundaries of human knowledge and explore the unknown. Now under construction at Las Campanas Observatory in Chile’s Atacama Desert, one of the premier locations on Earth for astronomy, the telescope will deliver the highest-performing combination of image quality, field of view, and light sensitivity ever achieved. From this southern hemisphere location, the Giant Magellan Telescope will use seven of the world’s largest mirrors to uncover the mysteries of dark matter and dark energy, investigate the origins of chemical elements, and search for signs of life on distant exoplanets.

When complete in the 2030s, the Giant Magellan Telescope will be one of the largest public-private funded science projects in history. It is the work of the GMTO Corporation, a 501(c)(3) nonprofit and international research consortium, founded by 16 universities and research institutions from the United States, Chile, Australia, Brazil, Israel, South Korea, and Taiwan.

Our culture is impactful, inclusive, and fearlessly innovative. We tackle the most complex engineering challenges and scientific questions alongside talented individuals who share a passion for advancing humanity’s understanding of the Universe.

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