Senior Staff Enterprise Architect

Job Description Summary

Senior Staff Software Architect to define and drive the data architecture and strategy for our customer-facing digital platform. This is a hands-on architecture role responsible for building a reliable, scalable and high-performance data foundation spanning data ingestion, ETL, relational data stores, search/indexing and the API serving layer. You will shape how data flows from multiple enterprise sources into Amazon RDS/PostgreSQL and Apache Solr, and how that data is efficiently exposed to customer-facing applications.
