You’re a doer who finds solutions and works independently.
Knowledge of JavaScript, Flutter or Python is a major plus, but we’re open to your expertise.
You have a genuine interest in using technology to improve people’s lives, implement nonprofit projects, and create social value.
You see yourself as part of the extended founding team and commit voluntarily 2–3 hours per week, flexibly, to grow with us.
Initiative, reliability and a willingness to try new things.
Good German and English skills.
