THE OPPORTUNITY

Data at scale requires more than infrastructure — it requires thoughtful engineering, high-performance pipelines, and reliable architecture.

We’re looking for Senior and Principal Data Platform Engineers to help build and evolve a large-scale data platform for an international technology company operating in the customer engagement, automation, and data-driven marketing space.

You’ll work on the foundations that make data accessible, enriched, secure, and ready for analytics — from Apache Druid ingestion pipelines and Kafka-based streaming to database optimization and access control.

If you enjoy solving complex data engineering challenges and building systems designed to perform at scale, this project offers an opportunity to make a meaningful technical impact.
