Manager, Battery Test & Validation Engineer

At Heart Aerospace we develop the ES-30, a regional hybrid-electric airplane with a capacity of 30 passengers, an electric zero-emission range of 200 km and an extended hybrid range of 400 km. Heart is targeting type certification of the ES-30 by the end of the decade.

Our headquarters is based in Gothenburg, Sweden and we are now opening up a R&D hub in Los Angeles, which will focus on the advancement of Heart's hybrid-electric propulsion system and other key technologies.

Your mission

Heart Aerospace is seeking a highly motivated and experienced Manager, Battery Test & Validation Engineering to join our growing and dynamic team.
