Staff Machine Learning Engineer
London, King's Cross
Top-of-market compensation
The Role
You'll take ownership of designing, building, and shipping production-grade systems that power ranking, personalisation, and reward structures in real time. You work hands-on with a small, high-ownership team. You have real influence over how we build our infrastructure as we grow it together.
You spot leverage points others miss: systems that shift behaviour, ranking that balances user value and business sustainability, measurement frameworks that prove what actually works. You own these end to end.
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 Own
- Ranking and personalisation systems that reach the right users in real time
- Reward and payout infrastructure balancing user motivation, cost, and business value
- Behavioural prediction through time-series and sequence systems
- Measurement and validation using A/B testing, causal inference, uplift modelling
- ML infrastructure: pipelines, training loops, serving, monitoring
- Technical leadership and mentorship on shipping discipline and impact
What We're Looking For
- Shipped production systems end to end, from formulation through impact measurement
- Full-stack capability: data pipeline to live serving to monitoring and decay
- Causal thinking: propensity scoring, instrumental variables, contextual bandits, uplift modelling
- Scale experience: built systems handling high-volume behavioural datasets and real-time inference
- Published work or equivalent research discipline
- Builder's mindset: energised by shipping. Zero-to-one experience valued
- Cross-functional: collaborate across engineering, product, and data science teams on measurement and infrastructure
