Senior Software Engineer, Node.js

We’re on the lookout for an ambitious Senior Fullstack Engineer (Backend leaning) to join our Engineering team at our office in Berlin. Join us in building the largest AI enabled fintech for healthcare!

We are building the AI-Driven Financial Operating System for European healthcare, solving the biggest challenges for patients and practices. We create what no bank or software platform can handle. Our all-in-one platform transforms chaotic administrative processes into intelligent, automated workflows, from patient care to billing to next-generation payments. Because we truly believe: healthcare should be less about paperwork and more about people.

You would be working on the full journey from a practice's first touchpoint with Nelly to their long-term success. We make sure every practice gets up and running quickly, and help them discover more of what Nelly offers - without needing ongoing hand-holding from internal teams.

That means owning the tools, flows, and experiences that reduce time-to-value during customer onboarding, and building the conditions for practices to grow their use of Nelly independently.
