Lead Data Engineer — AI Startup, London | £130k+ | Equity | London | 4 days onsite
We're an early-stage, well-backed AI startup building an automation platform for a large, traditionally slow-moving UK industry. Live with pilot customers, strong early traction, scaling hard toward revenue this year.
We're hiring our first Lead Data Engineer. You'll own the data architecture from the ground up: real-time pipelines, analytics infra, and the vector/ML data workflows that power our AI product. This isn't maintaining someone else's system, you're building it.
What you'll be doing
- Architecting and building the data pipelines and infrastructure behind our AI product
- Designing ingestion, transformation and storage for both operational and AI workloads
- Building and optimising vector search and ML data pipelines
- Setting the data standards, tooling and hiring bar as the first data hire
- Working directly with the founders, not three layers removed from decisions
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 bring
- 7-10 years in data engineering, with real ownership of architecture decisions, not just execution
- Strong Python, plus experience with tools like Spark, Airflow, Kafka
- Comfortable across relational (Postgres), NoSQL, and vector databases (Qdrant, Milvus, pgvector, or similar)
- A background that includes time at a larger, more established tech company, ideally followed by a move into an early-stage or high-growth startup
- You like building things from nothing more than you like maintaining what already exists
