Senior Full Stack Developer (m/f/d)

We're a young, well-funded health-tech startup on a mission to make quality care reachable for everyone.

This is your opportunity to join at an early stage, have a direct impact on patient health, and help shape our tech product from the ground up. As a Full Stack Developer with a frontend focus, you'll spend most of your time crafting fast, accessible, and intuitive interfaces while contributing across the stack, working hand in hand with product and design.
