Software Engineer

Posted: 2026-03-19

The DataOS team at AppsFlyer is building and operating a reliable, high-scale data platform that powers analytics and product capabilities across the company. We process more than 150 billion events per day and manage petabyte-scale historical data. Our team owns much more than a traditional "data lake" - including schema management, ETL pipelines, and interfaces to and from storage.

If you're excited by scale, ownership, and building production-grade data systems, we'd love to meet you.
