Data Engineer
Department: Technology & Data
Employment Type: Full Time
Location: Pure Offices, Leeds
Description
About the team: At Vintage Cash Cow and Vintage.com, technology is how we scale impact. Every customer journey, from sending in pre‑loved items to getting paid, is powered by the systems we design, the products we build, and the data we unlock.
Our Technology & Data team is at the heart of this transformation driving greenfield product development, experimenting with fresh ideas, and bringing innovative solutions to life. We’re building modern, scalable, and customer‑focused platforms that set the standard for the re‑commerce industry.
This is a team where curiosity meets craft: blending creativity, technical excellence, and a product mindset to deliver experiences that feel simple, rewarding, and future‑proof.
About the role: We’re looking for a hands‑on, detail‑loving Data Engineer to help us level up our data foundations and set us up for bigger, bolder analytics. This is our second data hire, which means you won’t just be maintaining something that already exists, you’ll be helping define how it should work end‑to‑end.
You’ll own the pipes and plumbing: designing and building robust data pipelines, shaping our warehouse models, and keeping data clean, reliable, and ready for decision‑making. A big part of your focus will be digital marketing and CRM data (HubSpot especially), so our Growth, Finance, and Product teams can move fast with confidence.
If you’re excited by building a modern stack, balancing build vs buy, and creating the kind of data platform that people actually love using, you’ll fit right in.
This role can be based in either the UK or the Netherlands.
Getting Started…
- Get familiar with our current data setup and BI stack (Snowflake, dbt, FiveTran, Sigma, SQL, and friends).
- Meet your key partners across Growth/Marketing, Finance, Operations, and Product to understand the metrics that matter most.
- Explore our core data sources (Adalyser, Meta Ads, Google Ads, HubSpot, Aircall, and internal platforms).
- Spot early wins: where pipelines can be simplified, data quality boosted, or reporting made faster and smarter.
Establishing Your Impact…
- Build and optimise reliable, scalable ELT/ETL pipelines into Snowflake.
- Create clean, reusable models that make downstream analytics simple and consistent.
- Put proactive monitoring and validation in place so teams can trust what they see.
- Reduce manual work across reporting and data movement through automation.
Driving Excellence…
- Help define and evolve our data architecture as we scale into new markets.
- Champion best practice: documentation, governance, naming conventions, testing, and performance.
- Partner closely with stakeholders so data engineering solves real commercial problems (not just technical ones).
- Keep one eye on what’s next: smarter tooling, AI‑assisted analytics, and ways to make our stack even more self‑serve.
