The ABAP Programmer plays a critical role in analyzing, remediating, and modernizing complex SAP custom code landscapes within Tessera’s AI‑native platform. This role blends deep ABAP development expertise—particularly custom code remediation, S/4

HANA adaptation, and performance optimization—with systems engineering discipline, integration design, and applied AI‑driven automation. You will work hands‑on within SAP ECC and S/4

HANA environments, performing detailed custom code analysis, configuring and executing ATC and readiness scans, resolving deprecated objects, and refactoring legacy ABAP to align with clean‑core and extensibility best practices. You will also support cross‑system integrations and enable AI‑driven automation across ERP and adjacent enterprise platforms. This role is ideal for an engineer who understands how SAP systems operate in real production environments—across application, data, and integration layers—and can modernize highly customized landscapes safely, govern ably, and intelligently using automation and AI.
