(Senior) Software Engineer, Rust

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!

What to expect in the role as Software Engineer, Rust

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 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 to expect

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.
