About the role

Key responsibilities & impact

Core data modelling: Design and own the core data models that everything else depends on, making them clean, trusted and easy to build on.
Modelling at source: Work inside the product and engineering codebase to ensure data is captured and structured correctly from the start, before it ever reaches the warehouse.
Pipelines: Build and maintain the pipelines that connect our systems, so data flows through the business correctly and reliably.
Self-serve platform: Make the data platform genuinely self-serve, so product, growth, commercial and ops teams (and our agents) can answer their own questions without coming to you.
Agents as consumers: Treat agents as first-class consumers of the data layer, structuring data so they can do analytical work accurately and at scale.
Metrics that matter: Partner with the team on the metrics that matter, from acquisition and activation through to matching quality and commercial performance.
Answers, not just queries: Turn ambiguous business questions into the right data model, the right metric and a clear answer.
Standards: Set the standards for data quality, definitions and instrumentation across Dex.

Requirements

What you’ll need

You've built the data foundation for a consumer product or marketplace before, and you know what good looks like at scale.
You're an engineer and an analyst. You can model and pipe the data, and read what it's telling you about the business.
Comfortable reading existing code and finding your way through a codebase you didn't write. You can pick up how a system models and emits its data, and confidently make changes within it.
Fluent across a modern analytics stack (a cloud warehouse, a transformation layer, orchestration and BI), with views on what to use when. We're open to changing our current choices and want someone who can tell us where they're right and where they aren't.
Commercially and product minded. You care about the metric and the decision it drives, not just the query.
You think about the platform, not the one-off answer. You build things other people (and agents) can stand on.
Intelligent, ambitious, with strong judgement. A good person who's fun to work with and makes things happen without being asked.
