💼 12-Month Contract
💰 £400-£480 per day
We’re looking for an experienced Data Modelling Specialist – Senior Python Developer to join a team working on enterprise data governance, metadata management, and data modelling within a highly regulated financial services environment.
You’ll be responsible for designing and maintaining data and asset models in Collibra, developing high-quality Python solutions, and building reusable automation to support data governance, data quality, lineage, integrations, and large-scale financial and risk data.
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.
