Helsinki, Finland

The Senior Electric Propulsion Architect will be joining the ReOrbit team in Helsinki to push forward the development of our propulsion systems for our Small Satcom project. This opportunity will enable you to be part of a very experienced team, embarking on the challenging mission of shrinking the size and reducing the cost of a GEO satellite while keeping its performance and life to its maximum capacity.

We are looking for someone who has previous experience working on electric propulsion systems mainly on GEO communications satellites, with a system-level perspective of propulsion. We are looking for a versatile engineer, who is confident to get on and get things done, big on teamwork and is flexible in their approach. We need someone who enjoys working with partners and suppliers and feels comfortable asking the difficult questions. This role will work alongside our existing propulsion engineers. We are looking for a person that has gone through the entire process of designing, implementing and testing propulsion systems in the past.
