Control Laws Engineer

What is JetZero?

Today’s aircraft contribute around 2.5% of global CO2 emissions, equivalent to the emissions of 200 million cars. This is only going to increase: Air travel is forecasted to double by 2050, while meaningful efficiency gains using current airplanes have hit a wall.

JetZero is developing a blended wing aircraft. It uses 50% less fuel and can accommodate zero-emission hydrogen propulsion. JetZero is the inevitable solution to sustainable air travel.

Position OverviewWe are seeking a dynamic and experienced Fly-by-Wire Aircraft Control Laws Engineer to join our team.
