Actively participate in sprint planning, code reviews, and team knowledge sharing
What we expect from you
You’re not just a developer – you’re a creator, problem solver, and a leader in your craft.
Experience developing mobile applications with Flutter in a commercial/production environment
Proficiency in back-end languages and frameworks (e.g., NodeJS, Express, TypeScript on Google Cloud/Firebase or similar)
Ability to design and build REST APIs and work with cloud platforms (Google Cloud or Firebase preferred)
Understanding of mobile-first architecture and building scalable systems
Familiarity with modern development practices such as CI/CD, automated testing, and agile methodologies
Effective communication in English (Dutch is a plus, but not required)
Bonus: DevOps experience (knowledge of Google Cloud Infrastructure and CI/CD for mobile apps, e.g., Bitrise)
