This is a rare opportunity — the kind of internship that doesn’t come around very often. If you’re looking to gain hands-on experience in web development, backend systems, and data-driven product engineering, this is for you. We are now looking for a highly motivated intern to join our Amsterdam-based team and contribute to our mission of making the world a healthier and fitter place.
During this exciting 6-month internship, you’ll join our Data team to help design and develop a web-based internal tool that supports how we process and leverage data from millions of users. You’ll be challenged in a fast-paced environment with exceptional learning opportunities. As a respected member of the team, you’ll take ownership of a real engineering project — from backend architecture to user interface. In addition, you’ll work closely with our data engineers and analysts, gaining practical experience in building scalable tools that turn data into actionable insights. So if you’re confident, ambitious, and driven to build things that matter, we’d love to have you on board.

During your Software Engineering Internship, you will be involved in the following activities:

• Build a web-based internal application to improve how the data team manages large-scale ingestion and processing pipelines.
• Develop clean, maintainable backend services to automate tasks and integrate with our databases, APIs and AWS services.
• Create intuitive frontend interfaces using modern web frameworks that allow non-technical teams to interact with data services.
• Work with SQL databases to store, query, and manage structured data securely and efficiently.
• Collaborate with data engineers and analysts to understand key workflows and turn them into reliable internal tools.
• Ensure high code quality through testing, documentation, and continuous integration practices.
• Apply basic principles of data governance and privacy to any data handling in your application.
• Participate in code reviews, agile standups, and team planning sessions to learn industry best practices.
