Data infrastructure and ETL platform for IT service partners

IT Services and IT Consulting Limassol 11–50 employees Privately Held

CoreStar operates a modular data platform built on AWS, Kafka, and ClickHouse, currently adopting Apache Airflow and dbt to scale ETL pipelines. The stack shape—streaming ingest (Kafka + Debezium), real-time analytics (ClickHouse), and emerging orchestration (Airflow)—signals a shift from batch processing toward continuous data pipelines. Hiring is concentrated in data (5 open roles) with mid-to-senior seniority, matching active projects around high-load platform work and real-time ingestion.
