Cesium is a team of passionate individuals working together to build the open metaverse through innovation, collaboration, customer focus, and continuous learning. Whether you’re an industry veteran or just starting out, you’ll get to work on interesting and challenging problems.

Cesium team member Hannah Pinkos teaches Alex to juggle at a refactor event in 2021.

There’s a reason I’ve been here for eight years and counting

“I started working at Cesium as an intern, and now I'm responsible for overseeing our Cesium ion SaaS platform which handles over 40 million requests a day.  Throughout my 8+ years at Cesium, I'm constantly facing new challenges and interesting problems to solve, giving me the opportunity to continually learn new things and grow both personally and professionally. From the beginning, I've felt like my input is valued and my contributions are impactful, as I've seen the amazing things the community has done with the innovative technology I had a hand in developing. I'm excited to see what the future of Cesium has in store.”

I wake up every day ready to change the world

“My favorite thing about being a 3D graphics developer at Cesium is the tangibility of my work. I love being able to see months of hard work come together to create an immersive 3D world. It’s rewarding to enable visual experiences that everybody, regardless of their background, can relate to. It takes no amount of technical description or jargon to show people what we do at Cesium, we bring the entire geospatially-accurate Earth into video games, simulations, and virtual experiences of any kind. At Cesium, we put a lot of focus on making geospatial experiences accessible for everybody, not just experts.”

Opportunities everywhere

“Here, I get to step up and take on opportunities that I would have a hard time imagining being available anywhere else. It’s amazing how quick that allows you to grow and learn. Through the Smart Construction team, I built both my technical abilities and communication skills exponentially. I’ve worked on cutting edge projects that allowed us to forge paths and set standards. And I’ve traveled the world representing Cesium.”

Alex Gallegos and Lisa Bos at a Cesium team refactor in 2021.

I've been working long enough to know what's important to me in a company

“I chose Cesium because it has all those things: visionary leadership; a culture that values collaboration, quality, and hard questions; smart, engaged colleagues; products I'm proud of and that are a force for good; and work that exercises my intellect and creativity. I'm incredibly happy with my choice.

3D and geospatial were new to me when I came to Cesium, and immersing myself in this space was challenging and inspiring. I'm constantly learning, but also bringing all my previous experience to bear.

I'm on a team using cutting edge geospatial and VR technology for the digital transformation of a mature industry - construction. This means I'm front and center for the realization of the metaverse, but in a concrete way that helps real people, right now.”

~ Lisa Bos - Product Management

Cesium team member Peter Gagliardi hard at work

I'm happy to work at a company that is committed to open standards and open source software.

“As a developer on the 3D Tiles team, we write specifications to enhance this open standard, and create reference implementations in CesiumJS. We're building a future not only for Cesium, but anyone who wants to stream massive geospatial datasets for the web.

I also enjoy the collaborative atmosphere at Cesium. Designing specifications involves plenty of whiteboarding, discussions, peer review, and engaging with community feedback. All our successes are big team efforts.”
