(Senior) Fullstack Engineer (m/w/d)

Are backend development, database design, and scalable architectures where you feel at home? Do you enjoy solving complex technical challenges and contributing your expertise to a strong, cross-functional product team? Then join us as a Senior Fullstack Engineer (m/f/d) and help us build robust, high-quality digital products – bringing the backend and database expertise that complements our existing strengths.

We develop new digital solutions for doctors and intelligently connect them with content, services, and industry partners. Our goal: a scalable, growth-oriented ecosystem that creates real added value in doctors’ daily work while also opening up new opportunities for other partners. We’re a fast-moving, experimental team with plenty of freedom to explore new ideas, make decisions, and shape how we build our products. To achieve this, we build two- and three-sided platforms and rethink content, tech, and communication – in an agile, modular, and user-centered way.

As part of the Thieme.Praxis product team, you will work closely with Product Management, UX, Engineering, and internal stakeholders from Marketing and Content. You will help bring key platform capabilities in-house, reduce vendor dependency, and take ownership of solutions from initial experimentation through to production.
