(Senior) Software Engineer, Rust

Department: Engineering

Location: Berlin

Employment Type: FullTime

We’re on the lookout for an ambitious Software Engineer, Rust to join our Engineering team at our office in Berlin. Join us in building the largest AI enabled fintech for healthcare!

You’d be joining our Integrations team, responsible for building connections between different practice management systems and Nelly backend systems. Working in the Integrations team involves building and maintaining Rust-based applications, from locally running clients to transaction-based backend systems. Since practice management systems are typically on-site at practices and have limited resources, we leverage Rust's platform-agnostic features and high performance to ensure seamless integration with the Nelly platform.

About Nelly

We are a Tech Company and we believe healthcare should feel a lot less like paperwork, and a lot more like people. So we’re building the technology that lets medical practices run smoothly, simply, and without all the admin chaos that slows everyone down. Our platform turns messy processes into smart, automated workflows, from patient journeys to billing to next-generation payments. Powered by AI, built for real humans, and designed to give medical teams the time and headspace they desperately need.

Why? Because Europe is facing a massive shortage of medical assistants. And if we don’t rethink how practices operate, the system won’t be able to keep up. We’re backed by €50M in Series B funding from world-class investors and are scaling fast to build Europe’s leading healthcare fintech.

Our vision: empower over a million medical practices and make life better for millions of patients. But here's the part we’re proudest of: we only work with nice people. No egos, no drama. Just kind, curious, hardworking humans building something meaningful together. If that sounds like your kind of place, welcome to Nelly.
