Mechanical Engineer

Seattle, WA

Next stop: The stratosphere

At Radical, we’re embarking on a mission to revolutionize how we connect and observe our planet. Our focus is on taking aerospace technology to new heights – literally. We are building high-altitude solar-powered aircraft designed to fly continuously in the stratosphere.

To date, we have successfully validated our technology using a subscale solar aircraft, which has flown non-stop for over 24 hours. Now, we are assembling a dynamic team of engineers and builders ready to propel our technology to the next level.

If you’re passionate about advancing innovative technology and love challenging engineering projects, Radical is the startup for you. Join us and push the boundaries of what’s possible.
