Data Lakehouse Developer

We are part of an international organization listed on Nasdaq Stockholm, operating in 11 countries. In Poland, we work with full autonomy. We independently choose our technologies, processes, and ways of working while maintaining the highest professional standards.

We deliver a wide range of IT projects in Poland and internationally, across multiple domains and technologies. This allows our consultants to develop their competencies and gain experience aligned with their professional ambitions.

Our collaboration is built around the CARE philosophy. For us, it means responsible project matching, transparent cooperation, and a long-term approach to professional growth.

Join us as Data Lakehouse Developer. The project focuses on building and maintaining a scalable Data Lakehouse architecture—using Apache Iceberg, Delta Lake, or Apache Hudi—to process data across the entire pipeline, from raw lake ingestion to refined presentation layers

Grow in an environment that cares about your development as much as you do.
