About this role
This role leads the design, development, and operation of data-utilization platforms for client companies, using the CX platform KARTE and data warehouse products. The work covers data architecture, implementation, and performance optimization, with a focus on connecting data engineering to business use and real-time customer experiences.
Responsibilities include designing and developing data platforms, and designing and building data collection and ETL processes for sources such as Web and app data, CRM systems, and core business systems. The role also optimizes data warehouses, including BigQuery, Databricks, and Snowflake, to process large volumes of data efficiently.
The position involves improving data architecture and building pipelines that balance real-time processing with data consistency. It also includes establishing data management environments that address security, privacy, and governance requirements.
The engineer works with consultants, analysts, and business-side stakeholders to define data requirements and assess their technical feasibility. Another responsibility is providing technical support for data-utilization frameworks that enable clients to operate independently. The work includes consulting-oriented engineering in addition to platform development.
The role addresses large and complex, multi-channel datasets held by major national clients across different industries. The resulting pipelines support customer actions through KARTE on a second-by-second basis, as well as data use in areas beyond KARTE. The position allows proposals and implementation of modern technology choices and architecture improvements in pursuit of return on investment.
