Solaris: Europe's Leading Embedded Finance Platform

Solaris is the number 1 embedded finance platform in Europe. As a BaaS (Banking-as-a-Service) pioneer, we build the bridge between smart financial technology and licensed banking. Founded in Berlin in 2016, we enable fintechs, digital ecosystems and global brands to embed accounts, cards, loans and payments seamlessly directly into their own products. The result: intuitive financial products that delight millions of users in their everyday lives. 

As a German full-service bank, we combine maximum IT security and regulatory strength with a modular, highly scalable infrastructure.

Now we are taking the next step: we are transforming Solaris into an AI-native banking platform, so that companies across Europe can scale secure, flexible financial products even faster.

Why you should join Solaris:

We are reinventing banking processes from the ground up, driven by intelligent automation, modular building blocks and directly integrated compliance. 

Tech meets banking. We manage our tech infrastructure from Berlin and our banking operations from Frankfurt.

Thanks to internal mobility, genuine career opportunities and the Solaris Academy, you can look forward to continuous learning paths, AI mentoring and targeted upskilling.

We stand for integrity, proactive risk management and lived equal opportunity, backed by concrete DEI initiatives.
