Balloon Fabrication Technician

About this position

Urban Sky is a venture‑backed aerospace startup on a mission to pioneer humanity’s routine, easy access to the stratosphere and the value locked within it. We design, build, operate, and sell stratospheric balloon systems. 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 DoW, 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 Texas and are seeking self‑starting, open‑minded, and hard‑working team members.

Urban Sky designs and manufactures one‑of‑a‑kind stratospheric balloons entirely in our North Denver facility. These balloons are constructed from a unique, airtight fabric and feature long, continuous seams. The manufacturing process includes patterning, seaming, adhesive bonding, and light mechanical assembly to attach plastic fittings to the balloon structure. While the balloons are lightweight and smaller than many traditional stratospheric balloons, they are significantly larger than typical sewn products such as clothing or outdoor equipment.

In this role, the candidate will be responsible for carefully following detailed work instructions and documenting each build step using provided quality and manufacturing templates. In addition to balloon fabrication, the candidate will periodically support other manufacturing activities, including assembling and operating test equipment, performing general shop upkeep, and assisting with cleaning and maintenance tasks.
