About Big Data Architect roles
Big Data Architect is a mid-level title within database architect work in the data space. Day to day, the role draws on PostgreSQL, AWS RDS/Aurora, Data modeling, and Performance tuning. Hiring teams evaluate candidates on how you frame ambiguous questions, choose methods, validate results, and turn findings into decisions. Because this title specializes in big data, examples drawn from big data work will carry more weight than general database architect stories.
Prepare both halves of the process here: tighten your resume around models, analyses, and dashboards tied to the decisions they informed and the lift they produced, then rehearse interview answers that walk through a situation, the decision you made, and a measurable outcome. A representative interview question for this field: “Walk me through how you approach designing a database for a new service that expects rapid growth.” Many candidates bring a background such as B.S. Computer Science.
