Balloon Fabrication Technician

About Urban Sky Urban Sky is a venture-backed aerospace startup pioneering the use of the stratosphere to transform how humans observe and analyze the Earth. We design, build, operate, and deploy stratospheric balloon systems that support applications ranging from real-time wildfire monitoring to advanced urban mapping. Urban Sky launches flight vehicles to the stratosphere on a weekly basis.

Our team is made up of engineers, makers, developers, and problem-solvers who believe in the power of innovation, teamwork, and hands-on execution. We foster a culture built on candor, inclusion, respect, and empowerment as we continue building the next chapter of stratospheric technology in Denver.
