Principal Security Engineer

About Vay

Imagine being able to say, “I helped launch the future of transportation.”
At Vay, we’re redefining urban mobility with our world-first Remote Driving technology. Customers simply request a vehicle, and it arrives on public roads with no driver inside.

Already operating in Las Vegas and expanding rapidly with strategic investment of up to $410 million from Grab, our mission is to replace private car ownership with a faster, cleaner, and more convenient door-to-door mobility experience.

We’ve already launched driverless vehicles on public roads in both Europe and the United States, built one of the largest commercial driverless fleets in the Western world, partnered with Kodiak to bring remote-driving technology to autonomous trucks, and completed tens of thousands of customer trips—with much more growth ahead.
