Job Description

Innovation is and will always be the core of SAP Fioneer, and it is the promise of why we were spun out of SAP: agility, innovation, and delivery.

SAP Fioneer builds on a heritage of outstanding technology and a deep understanding of corporate and consumer demands. At the heart of it all it is simple: We bring financial services to the next level with innovative software solutions and platforms.

We are helping companies in the financial services industry to achieve speed, scalability, and cost-efficiency through digital business innovation, cloud technology, and solutions that cover banking and insurance processes end-to-end.

A global company, with rapid growth, innovative people, and a lean organization makes SAP Fioneer a place where you accelerate your future!

About the team

We have various distributed teams working on our client's projects, internal tools, or in-house products. Our usual team size is up to 10 people, but we also have projects with multiple teams, some with well over 40 engineers.

Our teams consist of industry experts, product owners, designers, and software engineers focused on frontend, backend, or both. This is a great opportunity to get next-level experience in a mature cloud-native team on a challenging, business-relevant projects, including work at the forefront of GenAI and agentic systems.

As a team, we cherish flexibility and open communication. Focusing on work-life balance and enjoying the journey is a must. Taking responsibility and working at your own pace is something that we greatly appreciate. We'll be happy to show you everything we know, and we're looking for someone who can teach us just as much in return.
