Principal CAP & BTP Cloud Native Engineer (m/f/d)

About SAP Fioneer

SAP Fioneer was founded in 2021 as a joint venture between SAP and Dediq with one purpose: to provide the financial services industry with the software it needs to be future ready. We accelerate digital transformation in banking and insurance through a portfolio of cloud-native solutions, built on SAP Business Technology Platform and shaped in close co-innovation with our customers.

About the role

As a Principal CAP & BTP Cloud Native Engineer you take end-to-end ownership of backend topics across our cloud-native banking and development bank solutions. You design and build with the SAP Cloud Application Programming Model (CAP), SAP BTP services, ABAP Cloud and RAP. You set the bar for architecture quality, you deliver, and you make the people around you better.

This is a hands-on engineering role. We expect you to write code, shape architecture and own outcomes, not just produce slides.
