Join us as a Data Scientist

Want to do work that really matters?

At Checkatrade, we’re building the UK’s go-to home improvement marketplace. Every day, we help millions of homeowners find the right tradesperson for the job, fast, fair, and without the faff.

AI and data are at the core of that mission. We believe intelligence should drive every decision, workflow, and customer experience - helping trades win more work and homeowners get the right match, faster. We’re building an AI-powered Checkatrade where models, insights, and automation create real-world impact at scale.

As our next Data Scientist, based in Barcelona, you’ll join our Marketplace Team - the engine room where data meets behaviour. You’ll design intelligent systems that make our two-sided marketplace smarter and fairer: better search, faster matching, and more dynamic pricing. This isn’t about isolated modelling, it’s about shipping production-ready intelligence that directly shapes how millions of people find, choose, and hire trusted trades.

Forget long lists, here’s what you’ll actually spend your time on:

• Experimenting with LLM-based and retrieval-augmented models (RAG) to improve matching, ranking, and recommendations.
• Building prototypes that make our search and pricing systems more adaptive, efficient, and fair - powered by embeddings, reinforcement learning, and continuous feedback loops.
• Collaborating closely with engineers to productionise insights, ensuring our models aren’t just smart, but scalable and measurable in the real world.
• Working cross-functionally with product and platform teams to define how AI and data science integrate into every part of the marketplace experience.
• Contributing to our internal AI playbook - helping set the standards for experimentation, evaluation, and ethical AI in production environments.
  
  

It’s not about ticking every box. It’s about turning up curious, ready to crack on. You’ll do well here if you bring:

• Strong applied data science experience in modern Python stacks - PyTorch, TensorFlow, LangChain, or similar.
• Experience building and deploying production-grade models that solve real business problems.
• Comfort working across the spectrum, from quick-turn experiments to rigorous model evaluation and refinement.
• A pragmatic mindset: you know when to fine-tune, when to use off-the-shelf models, and when simpler is smarter.
• Curiosity, creativity, and a desire to turn data into tangible, measurable impact.
  
  

We believe great work deserves great rewards. Here’s just a taste:

• Great salary for the impact you make
• Annual bonus - get rewarded for your work
• Work your way - flexible, remote-friendly setup
• Lunch vouchers so you stay fuelled while you build
• Learning support for courses, certs and books to level up
• Real time off - generous annual leave plus local public holidays
  
  

Interviews will take place in Barcelona and you will be required to work in Barcelona 2 days per week.

If you require any reasonable adjustments during our interview process, please discuss them with your Talent Acquisition Partner.

If this sounds like the place where you can do your best work, we’d love to hear from you, even if you don’t tick every box
