Working Student/Intern Software Application Development (m/f/d)

What we are looking for

• You are enrolled as a student in computer science, business informatics, engineering or a related field.
• You love building things and have already built your own projects, at university or as a side project and not just tutorials.
• You have hands-on coding experience in Python.
• You have some experience with web frameworks and databases, for example React, FastAPI, Django or PostgreSQL. The exact tools are flexible; what matters most is that you want to learn and get things done.
• You are passionate about working on problems that have not been solved before and you appreciate an agile working environment.
• You like building projects from a blank page and taking ownership comes naturally to you.
• You like collaborating with others to develop our product and can communicate with non-software experts about software topics.
• You have an autonomous working attitude, you simply get started and you ask for help when you are stuck.
• You feel comfortable communicating in English in an international work environment
• PLUS: You have experience with cloud services such as AWS, GCP or Azure, Docker, or CI/CD.
• As a Working Student you can work 16 to 20 hours per week during the semester, ideally for at least 12 months. As an Intern you would work with us for 3-6 months. Both options can transition into a full-time position afterwards.

You do not tick all the boxes? We care more about your drive and what you have built than about a perfect CV. If you are keen to build things and add to our culture instead of just blending in, apply anyway.

What we care about

• Honesty : Being authentic and honest creates trust toward colleagues, customers, and business partners.

• We win and fail together : Fail early, fail often, fail forward. Failure is where the lessons are. We overcome challenges as a team.

What we offer

• Impact : Build software that is used in real production and helps in the fight against climate change.
• Growth : Learn from experienced engineers, grow your skills and try out new fields.
• Ownership : Own your projects from start to finish and shape an early-stage company.
• Fair pay : We believe in rewarding good work.
