# Senior Python + Data Systems Engineer

We are seeking a Senior Python + Data Systems Engineer for a US-based SaaS company in marketing analytics. Please note that the working hours for this position are until 11 PM Kyiv time. About the Client The client is an American SaaS company in marketing analytics. Its platform helps e-commerce brands understand which ad spend truly drives revenue. It collects tracking data, combines it with data from major ad platforms, and uses ML modeling to turn it into reporting. The company’s customers spend millions per month on advertising, so data volumes are large and business decisions depend on data accuracy. About the Project There are several projects in progress: Conversion API (main project): reprocessing tracking signals and delivering them to ad-platform APIs in real time. Each platform’s API works differently and has its own quirks, so integrations require careful work. Stack: Python streaming, Google Pub/Sub, Shopify JS tracking. Mobile attribution SDK (greenfield): a new SDK for JavaScript and iOS. Analytics data pipelines: pipelines built as part of the SaaS product, not internal BI. Full-stack product development: application features and integrations. Requirement
