About Urban Sky:

Urban Sky is a venture-backed aerospace startup that pioneers utilization of the stratosphere and reimagines the way humans view and analyze the earth. We design, build, operate, and sell stratospheric balloon systems, and the data we collect supports a wide range of applications, from real-time wildfire monitoring to urban mapping. Our technology is also employed by government customers including the Department of Defense (DoD), NASA, and others. Urban Sky sends flight vehicles to the stratosphere on a weekly basis.

Our team consists of engineers, makers, developers, and doers who believe in the power of human potential when passion meets utility within a small, supportive team. At Urban Sky we strive to create a team culture grounded in candor, inclusion, respect and empowerment.

We aim to build the next chapter of stratospheric history in Denver and are seeking self-starting, open-minded, and hard-working team members.

Urban Sky manufactures one-of-a-kind stratospheric balloons and payloads from start to finish in our facility in North Denver. These balloons are made of a unique airtight fabric and involve long continuous seams. Making balloons involves patterning, seaming, adhesive bonds and some light mechanical work adjoining plastic fittings to the balloons. The balloons are very lightweight and relatively small compared to other stratospheric balloons, but quite large when compared with things like clothing and outdoor equipment. Urban Sky is searching for an Engineering Technician responsible for developing and executing tests on prospective and existing materials to improve our products.
