Brighton | Hybrid (3 days in office) | Up to £90K
I'm partnering with one of the world's leading online marketplaces, currently investing heavily in Data & AI as they transform into a truly product-led organisation.
They're hiring a Product/Decision Scientist to join one of six cross-functional product squads, working alongside Product Managers, Engineers and Designers to build customer-facing features, influence commercial decisions and develop AI-powered experiences.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Rather than sitting in a central analytics function, you'll own data within your squad, helping shape roadmap decisions from idea through to delivery and measuring the impact of what gets built.

- Partner with Product and Engineering to solve commercial and customer problems.
- Lead experimentation, opportunity sizing and product performance analysis.
- Build recommendation models, segmentation solutions and AI-powered product features.
- Develop lightweight data products, automation and proof-of-concepts.
