Hiring: Sr. Data Engineer, Amazon Digital Advertising Company: Amazon Location: Boulder, CO Job Posted Time: 2026-09-17 05:20:16 Target Skills & Keywords : Data Warehouse, EMR, ETL, Hadoop, Hive, Java, Node.js, Python, SQL, Scala, Spark About the job Experience: •5+ years of data engineering experience Required Skills: •Are you excited by the idea of building the data foundation that an entire AI-powered product is built on — from the very first pipeline? Do you like the messy, ambiguous problems: wrangling inconsistent data from dozens of outside partners and turning it into something clean, timely, and genuinely trustworthy? If so, we'd love to talk. •You won't just be maintaining pipelines. You'll help shape how data flows through a brand-new system and decide what "good" looks like for schemas and data quality. It's a small, scrappy team with a lot of ownership to go around, and you'll get to leave your fingerprint on something from the ground floor. •If building trustworthy data infrastructure for hard, never-been-done-before problems sounds like your kind of challenge, we'd love to hear from you. •Design, build, and operate scalable, reliable data ingestion pipelines that collect marketing data from agencies, ad tech vendors, and internal sources on scheduled intervals — without requiring source teams to change their current processes. •Define and evolve input schemas and normalization logic that reconcile inconsistent granularity, formats, and terminology across sources into a unified dataset. •Build automated data quality validation, anomaly detection, and reconciliation to catch and surface defects early, reducing manual auditing and cleaning effort. •Handle real-world data complexity, such as delayed settlement of certain data sources, mapping records to the correct hierarchies, and deciding when to use planned versus finalized data. •Partner with modeling and AI engineers to ensure the data foundation is structured for downstream analytics, agent orchestration, and natural-language query.
