We are looking for a Senior Data Platform Engineer to build out services and ingestion related to a knowledge graph. This knowledge graph aims to unify insights on data processing—job telemetry, SLA expectation and attainment, data quality, infra incidents—using job lineage to build a comprehensive and predictive view of data processing ‘health’ across all of Apple Services data engineering. You’ll apply your expertise in data systems to design, build, and support ingestion services to feed and manage data in the knowledge graph (a graph db), and be a part of coming up with new ways to classify and represent data via agentic workflows, to increase the insight available from the graph. We believe graph-based insights can be used to power operational excellence, by capture production issues, driving analysis, guiding resolution of issues and enabling proactive avoidance of future incidents. You’ll work alongside a Dublin based team of data and other software engineers committed to bringing the knowledge graph to life. You will have a tremendous amount of individual responsibility and influence over the direction of this critical service for years to come. Additionally, you will have the chance to interact with various other teams, each with unique skill sets and operating in different time zones.
