Build and operationalize AI-powered solutions, intelligent agents, and data products that improve internal productivity, customer engagement, campaign optimization, and self-service access to data and insights. Define and enforce platform standards for schema evolution, data lineage, governance, metric consistency, access controls, naming conventions, and data quality SLAs across the organization. Improve operational excellence across the data ecosystem through monitoring, alerting, freshness validation, schema drift detection, incident response, root cause analysis, and production support, while leading technical design discussions, architecture reviews, mentorship, and adoption of AI-assisted engineering practices. About You: Education: Bachelor's degree in Computer Science, Engineering, Information Systems, Mathematics, or a related technical field required. Master's degree preferred. Experience: 5+ years of experience designing, building, and operating production-grade data platforms and distributed data systems. Strong experience developing scalable data products, semantic layers, and analytical data models supporting enterprise reporting and activation use cases. Demonstrated expertise in dimensional data modeling and Kimball methodologies, including fact and dimension modeling, conformed dimensions, SCDs, and metric governance. Experience supporting customer data platforms, marketing technology ecosystems, or data activation platforms is highly preferred. Proven ability to write technical design documents, evaluate architectural trade-offs, and deliver scalable engineering solutions. Experience operating in fintech, financial services, adtech, or other highly regulated industries preferred. Strong communication and stakeholder management skills with experience collaborating across engineering, analytics, product, and business teams.
