As a Senior Data Engineer (Databricks) at Massive Rocket, you'll build the data foundation that powers modern, event-driven customer engagement for our enterprise clients.

You'll design and maintain scalable data pipelines that move customer data from complex legacy and operational systems into Databricks, and onward through platforms such as mParticle and Braze.

Working as part of an embedded Agile delivery team, you'll combine strong data engineering expertise with an understanding of customer data, identity resolution, CDPs, and Martech activation. You'll play a key role in replacing fragmented, batch-based processes with reliable data foundations that support real-time customer engagement.
