Help us build the future of 3D geospatial

Massive amounts of 3D data are being collected about our world every second. We're building the technology to make sense of that data—to process it, visualize it online, tie it to real world coordinates, and ultimately make it and the insights within it wildly accessible.

Our values

We're a small and growing team that is passionate about pushing our limits, working together to solve hard problems, and learning every day. We believe that understanding the prolific data being collected today and connecting it to the world geographically will unlock new and important insights—and therefore it needs to be as accessible as possible. Our roots are in open source, and we're actively developing CesiumJS and contributing to other open source projects. We're building something entirely new and are excited for that challenge.

As we build our platform, we're also building our company—together. We default to transparent communications, collaborate on decisions that impact our team and our bigger picture, and push ourselves to listen, be empathetic, and strive for excellence in all parts of our work.

Finally, we value community. We're active in our local and online communities and attend code sprints, teach at local universities and bootcamps, present at and organize conferences, write technical books, and support initiatives we believe in.


We strive for excellence in our code, in our communications, and in how we work together.

Continuous improvement

We're creating something that's never been built before. This requires relentless curiosity, honest feedback, acceptance of failures, and iteration.


We're building Cesium—our platform, our team, and our company—together. And we're better for it.
