We're hiring a Data Architect to shape the data platform for a large, established UK organisation going through a major transformation. It's a regulated, high-scale environment, and you'll own the target architecture for a move off Oracle onto Snowflake.
You'll set the direction other engineers build against.
What You'll Do
- Design the target data architecture: lakehouse and warehouse patterns, modelling standards, and how data flows across the platform.
- Own the migration strategy from Oracle to Snowflake, including sequencing, risk, and how legacy and new run side by side.
- Set modelling conventions and governance the wider data team works to.
- Work closely with engineering leads and stakeholders to keep the design grounded in what actually ships.
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.
What We're Looking For
- Strong track record architecting data platforms at scale, with Snowflake front and centre.
- Deep experience with lakehouse and warehouse design and dimensional modelling.
- Hands-on experience planning and running Oracle to Snowflake migrations.
- Comfortable in a regulated environment where lineage and governance matter.
- You design for teams that build with AI-assisted engineering, and you're comfortable using AI tooling in your own work.
Bonus points for dbt, AWS, and experience in financial services or asset finance.
