We are committed to rewarding top performers, offering very competitive pay and benefits, and providing tremendous career development opportunities. We are seeking a Senior Enterprise Integration Engineer to play a key hands-on role in designing, building, and supporting enterprise integrations across SAP and non-SAP applications, external business partners, and enterprise data and analytics platforms. This role is a key contributor to our integration modernization strategy, supporting SAP BTP Integration Suite, B2B/EDI partner connectivity, and analytics and data platforms that consume data from a variety of enterprise and external sources. SAP Business Technology Platform (BTP) serves as the primary middleware, alongside other enterprise integration platforms (such as Azure Integration Services and BizTalk) where appropriate, for integrations connecting SAP S/4HANA with SAP and non-SAP systems. This role blends systems integration engineering (connecting enterprise applications and platforms) with data engineering (building reliable data pipelines and data integration patterns, including batch, streaming, and virtualized access, for downstream analytics and reporting). This position is well-suited for a senior engineer who is comfortable owning integration solutions end-to-end while collaborating closely with SAP, application, infrastructure, and analytics teams. The role emphasizes designing integrations with built-in, automated monitoring and alerting, enabling proactive detection and prevention of failures across enterprise interfaces rather than reliance on manual monitoring.
