The reporting is only as good as the pipelineunderneath it. This role owns that layer: the ingestion, the transformations,the checks, and the support when a number downstream does not match.
It is a permanent seat in Centurion, in a retailinvestments technology team, reporting to the Head of Application Development.You will build and run data pipelines and the platform they sit on, soanalytics, BI and the business get data they can trust. You will also settechnical direction in the team. That means design calls, engineeringstandards, and how AI is used in the work without breaking governance.
What you will do
- Deliver data engineering work inside an Agile team. Plan it,estimate it, break features into tasks, and hit the quality bar you agreedwith the product owner.
- Design and build ingestion and transformation pipelines acrosssystems and domains. Batch and incremental. Error handling, monitoring,alerting, validation and reconciliation included.
- Shape solutions that fit the target data platform. Theenvironment is cloud and AWS-aligned. You will be expected to call thecost, security, performance and support impact of a design before it isbuilt.
- Coach less experienced data engineers. Give analytics, BI anddata science a clear view of structures, availability and how a pipelineactually behaves.
- Review code and configuration. Simplify what is already there.Use Git, automated testing, CI/CD and structured releases. Document enoughthat someone else can support it.
- Use AI in the engineering workflow, on approved tools only. Youvalidate the output. You do not put client or proprietary data into apublic model. You stay accountable for what goes to production.
- Join incident response and root-cause work when a pipeline fails,and build privacy, access control and regulatory requirements in from thestart.
