We’re on the lookout for an ambitious Senior Software Engineer with focus on Python to join our Engineering team at our office in Berlin. Join us in building the largest AI enabled fintech for healthcare! About Nelly 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. Why? Because Europe is facing a massive shortage of medical professionals. And if we don't rethink the way practices work, the system won't be able to keep up. With our Series B funding of over €50 million from world-class investors, we are turning our vision into reality. What sets us apart: We work with the best team, which is why we give everything together every day. We believe in Talent Density, because exceptional people make everyone around them better. At Nelly, we move fast and expect everyone to keep up. Stagnation isn’t an option, which is why we invest heavily in growth. AI isn't a nice-to-have at Nelly. We expect you to use it every day and give you everything you need to do so. You get trust and ownership and we expect you to speak up, even when it's uncomfortable. What we offer: Deutschlandticket (public transport pass covering all of Germany) or Swapfiets membership, so you get around the city fast Urban Sports Club membership, for sport and balance Flexible working hours and a hybrid setup Up to 4 weeks of workation A dog-friendly office with great vibes and a team that's fun to work with Snacks and a fridge full of cold drinks We welcome applications from people of all genders and backgrounds, regardless of origin or age.
