Data Engineer
We are seeking a Data Engineer (Databricks / Spark) to join a lean, engineering-focused team building a new data platform for a global payments technology company. In this role, you will work closely with our Tech Lead and the client’s engineers to build Databricks on AWS pipelines across a medallion architecture, develop ClickHouse structures for real-time analytics, and own the quality of your code end to end, from automated tests to data quality checks, while giving pragmatic support to a legacy Hadoop platform.
Essential functions
New Platform Development: Build pipelines and data transformations on Databricks on AWS, developing Bronze, Silver and Gold layers as part of a platform that unifies the engineering approach across many consumers and use cases.
Spark Performance: Develop and optimize Spark / PySpark workloads, including those behind monthly reports for around 40,000 merchants.
Real-Time Analytics: Build ClickHouse ingestion and analytical structures for low-latency use cases.
Engineering Quality Ownership: Implement automated tests, integration tests and data quality checks yourself, with no dedicated QA on the team, and take part in code reviews.
Legacy Platform Support: Troubleshoot production issues and deliver targeted fixes in a legacy Hadoop platform with file-based sources and Kafka streams (around 10% of your time).
Reusable Patterns: Contribute to shared engineering patterns that become the standard for the new platform, with potential growth into AI/ML and MLOps.

Spark / PySpark: Strong practical skills in developing and optimizing Spark workloads.
