Senior Fullstack Engineer (f/m/d) - Berlin I Germany | EU I Remote

How will you make an impact? As a Senior Full Stack Engineer, you'll work at the intersection of engineering and product to shape how our users build with Hygraph. You'll ship features that solve real customer problems, contribute to our CMS core, extend our platform capabilities, and help bring AI-powered features to life.

Then fix them, don't just flag them. Contribute to architectural decisions that keep
