Our Mission Human time and effort is the rarest thing in the universe. The fact that so many people hate what they do for work is a disaster on so many levels. How many people live quiet lives of misery? How many generational talents do we miss due to circumstance? Dex’s mission is to close the gap between Talent & Opportunity, we believe that work, and being productive, is part of the human condition, that regardless of AI, human passion, ingenuity and a desire to do things means that work will always exist. We are building Dex to create a future where technology helps every individual to understand their strengths, interests and unique abilities, and to connect with opportunities where they can thrive, because more people doing things they love leads to a better, happier and more productive world. We are starting by connecting the world's most ambitious software engineers with the companies that deserve them. The Role 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, and right now that intelligence lives in too many places. 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. We use agents for a huge amount of our analytical work, which means the quality of our data layer is a force multiplier. Get it right and every person and every agent at Dex gets faster and sharper. You'll own how data is modelled, how it flows between our systems, and how internal teams self-serve on top of it, building on what's already driving the business rather than starting from a blank page. As the first dedicated data hire, you'll set the standards and build the function out behind you as Dex grows. It's a chance to define how an AI-native company builds on its data from the ground up, in a market with a real dearth of well-built data foundations. We think there's a generational company to be built in this space, and we believe it's going to be Dex. What You’ll Do 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. What we’re looking for 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.
