Stress Engineer

Forres, Moray, United Kingdom
Full Time

We are looking for an experienced Stress Engineer, skilled in the structural analysis of mass efficient structural parts for high performance applications such as aerospace, motorsport or defence, experience of composite parts would be ideal. You will join our team manufacturing our orbital launch vehicle here in Forres, working with experts in the field to produce our state of the art orbital launch vehicle. 


Orbex is a leading micro-launch company with our Prime vehicle being prepared to launch from our home spaceport, Space Hub Sutherland.
