Senior Mechanical Design Engineer

Building the space between proven and possible, MDA Space is a trusted mission partner to the global space industry. A robotics, satellite systems and geointelligence pioneer with a 55-year+ story of world firsts and more than 450 missions, MDA Space is a global leader in communications satellites, Earth and space observation, and space exploration and infrastructure. The MDA Space team of more than 3,400 space experts in Canada, the US and the UK has the knowledge and know-how to turn an audacious customer vision into an achievable mission.

We’re on the hunt for a Senior Mechanical Design Engineer at our Stevenage, Harwell or Manchester office. MDA Space’s international footprint in the UK creates opportunities to work with some of the most exciting space industrial players in the country. Delivering all three business area capabilities in Geointelligence, Robotics & Space Operations, and Satellite Systems, our UK team provides support to our European-based customers while specializing in the development of advanced space sensors for exploration missions as well as space-based communication technology.

As our presence grows overseas, so does our need for new ambitious team players to help us advance our place in the Universe and beyond.
