About the role
TL;DR
Define Dex's data foundation from the ground up.
- •Dex runs on data.
- •Our matching, our product decisions, our growth, our commercial bets all depend on understanding what's actually happening across the business.
- •This is a founding role to own the data foundation of Dex end to end: the data models underneath everything, the pipelines that connect our systems, and the data platform that the whole company (and our agents) builds on top of.
- •Key Responsibilities 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.
- •Requirements 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.
