Role Summary

The Systems Engineer- ERP plays a critical role in designing, modernizing, and integrating SAP-centric enterprise landscapes with Tessera’s AI-native platform. This role blends deep SAP technical expertise—particularly ABAP development and S/4HANA modernization—with systems engineering, integration design, and applied automation.

You will work hands-on with SAP ECC and S/4HANA systems, analyze and remediate custom ABAP code, design cross-system integrations, and support AI-driven automation across ERP, CRM, and finance platforms. This role is ideal for an engineer who understands how SAP systems actually run in production and wants to modernize them safely using intelligent automation.
