BPX is hiring a Senior Data Engineer as we build out a dedicated Data capability alongside our Intelligent Marketing practice. You will build and run the pipelines, models and data products that feed enterprise front-office programmes, turning raw customer, product and interaction data into clean, trusted, activation-ready data. Snowflake is the core platform on our largest current programmes, connected to Twilio Segment, Braze and Amplitude, and you will also work on Databricks, BigQuery, Azure and AWS as client needs demand.
Tasks
- Build and maintain ingestion pipelines from source systems, event streams and third-party platforms into the cloud data platform.
- Develop and test transformation logic and data models, turning raw data into clean, documented, reusable customer and event datasets.
- Prepare activation-ready data for CDPs and engagement platforms, including audience tables, traits and warehouse-native or zero-copy sync patterns.
- Work with data architects to implement target-state designs, and raise practical issues early so the design holds up in production.
- Build data quality checks, monitoring and alerting, and diagnose and fix pipeline and data issues quickly when they arise.
- Re-test and update downstream flows when source systems or platform architecture change, so CDP, engagement and reporting keep working.
- Apply security, access control and privacy standards in every build, including GDPR and consent data handling.
- Use version control, CI/CD and code review as standard, and document pipelines so client teams can support them.
- Contribute to BPX's Data capability through reusable pipelines, templates and engineering standards, and support scoping and effort estimates.
