We're partnering with an innovative business building its data science capability in-house for the first time. Join them at the ground floor to shape the future of their data function and directly impact customer retention and business strategy.

The Role

  • Shape and define the data science function from the ground up
  • Take ownership of the full data science lifecycle, from modelling to production-ready solutions
  • Focus initially on customer churn and complaint propensity, forecasting, and predictive modelling
  • Build models, document methodologies, and establish scalable approaches
  • Work independently to take models from concept through to productionisation

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

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.
