Data Quality Engineer
£80,000 | London | Trading Scale Up | Python, SQL, TypeScript
Crypto markets move at machine speed. Somebody has to make sure the data isn't lying to us. I'm recruiting for a London capital markets firm built for the onchain world.
They're making waves with an already impressive team and are looking for someone to own the visualization and observability of the market data platform.
They run their own proprietary trading infrastructure, and the market data it produces is good enough that institutional clients now pay for it directly. It's grown into its own product, and they're pushing further.
They just picked up rights to distribute a major prediction markets data feed.
They're after a Data Quality Engineer, and this one's a strong fit if you've written proper Python, built dashboards, and spent real time in and around data pipelines.
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 you'll actually be doing:
- Building dashboards across live exchange feeds, historical datasets, venue health, latency and gaps, using Python and TypeScript.
- Writing the checks and pipeline logic that catch problems in data before a client ever sees them.
- Defining what "good data" really means, not just whether a job ran, but whether the numbers coming out the other end hold up.
- Reconciling order books, trades, funding rates and derivatives across CEX and DEX venues.
- Working closely with engineers to trace issues back through the pipeline to their root cause, not just patch the symptom.

What they're looking for:
- Strong hands-on Python, comfortable writing real production code, not just scripts.
- Experience building dashboards, in Python or TypeScript, that people actually used to understand what was going on.
- Solid working knowledge of data pipelines, how they're built, where they break, and how to instrument them properly.
- 2+ years somewhere the output genuinely mattered, data quality, data engineering, or similar.
- A real eye for data that's subtly wrong, not just loudly broken.
