Senior Data Engineer - SAP HANA Cloud & Graph

We are looking for a Senior Data Engineer with serious depth in SAP HANA Cloud and graph databases to own the data layer beneath OMS+ IA. Our product lives on top of large, complex, deeply interconnected enterprise data, and the quality of that data layer sets the ceiling for everything built above it.You will model and optimize on HANA Cloud, and design graph data models that let the product answer connected questions relational queries handle poorly. Things like material substitutions and compatibility, product and customer hierarchies, and supply and fulfillment networks. You will also make sure that layer serves our machine learning and search engineers well, since their pipelines start where your work ends. Key Responsibilities Design, build, and optimize data models on SAP HANA Cloud, including tables, calculation views, CDS artifacts, stored procedures, and SQLScript. Design and implement graph data models and traversal queries for connected-data problems such as material substitution and compatibility, product and organizational hierarchies, and supply and fulfillment networks. Write and tune high-performance SQL and SQLScript: read execution plans, find the real bottleneck, and fix it. Assist with performance engineering across the data layer — partitioning, indexing, memory management, workload classes, and result caching. Build data ingestion and replication into HANA Cloud from SAP and non-SAP sources using things like SDI, SDA, SLT, change data capture, or compar
