Join us in building the largest AI enabled fintech for healthcare!\nAbout Nelly\nWe 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.\nWhy? 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.\nWhat 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 is an essential part of how we work 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.\nAbout the Team\nYou 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.\nThat 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.\nYour main customers will be practice medical staff and internal Nelly teams.\nJoining us, you will:\nBuild patient and doctor experiences, financial systems, and AI-powered products used across our platform.\n\nWork with technologies such as TypeScript, Node.js, React, Next.js, and more. We host everything on AWS and manage our infrastructure as code.\n\nCollaborate closely with product, design, and data to ship impactful, user-centric features.\n\nSee your ideas go from concept to implementation, impacting customers within your first few days.\n\nMake a significant contribution to defining, maintaining and improving our architecture and best practices.\n\nJoin a driven, highly skilled, engineering team and collaborate with talented professionals - learning from their expertise and contributing your own.\n\nWhat you'll bring:\n5+ years of experience in software engineering\n\nProficiency in TypeScript a Node.js / React\n\nExperience in data and API modelling, and cloud platforms like AWS\n\nAdvanced SQL skills with hands-on PostgreSQL performance optimization\n\nKnowledge of software engineering best practices for the full development life cycle\n\nA pragmatic mindset and strong sense of ownership\n\nTeam player with excellent communication skills\n\nWhat we offer:\nThe people you get to work with. You will work alongside the brightest minds we could find, on hard problems, as a team. We take on challenges together and we never forget to have fun doing it.\n\nRoom to grow faster than almost anywhere else. New challenges, more scope, real ownership from day one. We trust you to own it and to speak up when something is wrong. Just do not expect to stand still.\n\nA yearly learning and development budget, plus the coaching, feedback and internal knowledge that actually move you forward. Real investment in your learning.\n\nA front row seat while we build something big. We are building the financial operating system for European healthcare, with AI woven into how we build, sell and support. Real scope, real impact.\n\nDeutschlandticket or Swapfiets membership.\n\nUrban Sports Club membership.\n\nFlexible working hours and a hybrid setup and up to 4 weeks of workation.\n\nA dog friendly office.\n\nWe welcome applications from people of all genders and backgrounds, regardless of origin or age.
