Your Responsibilities

• Coordinate with internal teams, and users of the Platform
• Document your work, both for users of the infrastructure as well as for fellow developers
• Ensure the security of our services

Your Profile

• University degree in computer science or a related field. Alternatively, you have roughly equivalent experience to a university degree

• Personal development: At our company, there’s no one-size-fits-all approach to career growth. We grow together and support you with whatever you need to advance
• People-Centric: Our strength lies in our diversity. We respect each other just as we are. We also care deeply about balancing work, family, and personal life. We’ve been certified in this area since 2025
• Competitive salary: You can expect an annual target salary starting at €65,000 gross—and potentially higher depending on your qualifications and professional experience—consisting of an attractive base salary and a performance-based bonus.
• Flexible Work: 12 locations in Germany, a shared desk model, trust-based working hours, and flexible part-time options. There’s a model to suit everyone
• Sun, beach, or mountains: Want to work in another EU country? No problem—you can work remotely within the EU for up to 20 days a year
• Great benefits on top: Look forward to bike leasing, a company fitness program, discounted commuter passes, Secudog, and much more
