Passionate Team

Our team works at the intersection of 3D, mapping, and the web. We are passionate about crafting world-class software, realizing the potential of 3D mapping, and teaching and learning from new team members, from interns to experienced developers.

Born in Aerospace

The Cesium team is part of AGI, a real aerospace company. You may find yourself having lunch with a rocket scientist or hanging out at our Commercial Space Operations Center, tracking satellites in real-time (it's built on Cesium, of course).

Open Source

Much of our work is open source. We collaborate with the community on GitHub, mentor students on open-source projects, and participate in events such as code sprints and hackathons.

Industry Impact

When we're not writing code for Cesium, you may find us contributing to open standards, writing books, teaching computer science, or presenting at or organizing conferences.

Ridiculous Perks

Free meals, snacks, and beverages, casual dress, flexible hours, and onsite gym and laundry top the list of AGI's great perks. AGI also offers an outstanding salary, benefits, retirement, and development hardware.
