• Proven willingness to take ownership beyond your comfort zone and move tasks forward quickly with a results-driven mindset.

• Good analytical and structured thinking skills to evaluate scenarios in advance and turn them into practical solutions.
• German at ideally C1 level and good conversational English.

• Fast decision-making through flat hierarchies and direct access to leadership.
• High ownership and freedom in shaping and improving your work.
