The Calculation Engine team is responsible for a central orchestration layer within HANA core, that can handle complex relational and non-relational workloads. The component is the key engine for several SAP applications (B/4, IBP, MDS, …) as well as customer modeled scenarios, reflecting a broad range of usage scenarios.

With a strong focus on performance and stability, you will extend the existing codebase, develop new designs and add new features to the powerful HANA Database engine and the information modeler runtime plug-in that provides the back-end for modelling clients.

Modeling refers to enabling data in database tables for analytic consumption. This is done by combining tables in views, refining the data and by adding additional semantics such as dimensions, measures and hierarchies. These views can be used by analytic clients and MDX for reporting and decision making.

To create views, you need a client application (e.g. SAP HANA Modeler or SAP Web IDE) and a HANA component which checks the view definition and compiles it in a runtime representation.

Performance optimizations, testing and monitoring - both on premise and in a cloud environment - will be part of your daily work:

  • Write software implementations using C
