Do you build apps and scalable platforms â not just features?
Have you developed React and React Native applications, built Python backends, integrated Stripe subscriptions, and successfully published apps to the App Store and Google Play?
Do you work AI-first and use AI both inside the product and in your development workflow?
Then join Erdbaron as Senior Fullstack SaaS Developer (AI-Focused)
Erdbaron builds AI-driven apps and digital platforms in the field of geotechnics, material flow management and regulatory infrastructure.
We develop web applications, mobile apps and backend systems that combine automation, subscription models, AI-based features and scalable cloud architecture.
We are looking for a strong fullstack developer who understands how to build and ship production-ready apps and platforms â from frontend to backend, billing, publishing and AI integration.
