System Engineer for Exploration, In Space Transportation and Servicing (m/f/d)

The Directorate of Predevelopment, Proposals and Space System Studies is a strategic cornerstone of the company’s project pipeline. It drives the early shaping of future space missions by translating customer requirements into technically sound and competitive concepts. Within this directorate, the Department of Science, Exploration and Space Safety Missions focuses on the conceptualisation and maturation of missions related to astrophysics, planetary science, robotic solar system exploration, space safety, planetary defence, space weather, in-orbit servicing, in-space logistics and debris mitigation. By bridging scientific ambition with engineering feasibility, the department plays a key role in securing the OHB’s leadership in future international space programs. Within this department, the Exploration In-Space Transportation and Servicing team focuses on missions related to Exploration in Earth Orbit, Moon and Mars surface and environment and to in-space transportation and servicing in Earth orbit and beyond.
