Senior Data Scientist
Full Job Posting
The Role
Our Business Analytics team is growing! We’re looking for a Senior Data Scientist to join our team in London.
In this role you will own the models that drive our forecasting and strategy, from the data infrastructure behind them to the experiments that prove them out, turning statistical and machine learning work into reporting the business actually acts on.
Key Responsibilities
- Own the infrastructure and outcomes of our models, building algorithms and pipelines to merge, manage and interrogate data for tailored reporting
- Design and run experiments to test hypotheses and sharpen how we forecast
- Select, build and evaluate the most appropriate statistical and machine learning models for each problem
- Turn model output into clear, decision-ready reporting that shows how customers and clients interact with our business
- Raise the modelling bar across the analytics team, challenging and working alongside AI rather than deferring to it
About You
Several years building and shipping statistical and machine learning models in production, ideally in a commercial or performance-driven setting
Fluent in Python and SQL, and comfortable owning model infrastructure end to end
Strong on experiment design and model selection, and honest about how to evaluate what actually works
Able to translate complex modelling into clear reporting that non-technical stakeholders can act on
You challenge AI rather than lean on it, using it to move faster without losing rigour
You thrive when working as part of a team
Comfortable in a fast-paced environment
Have excellent written and verbal English skills
Last but not least, you’ll have no ego!
What You’ll Get
Private Health Care (Bupa)
Hybrid Working (3 days in office)
Travel Insurance
Competitive Base Salary
Company Bonus Scheme
Paid for AI Subscription (Claude / ChatGPT / Gemini)
Market-Leading Training Programme
Recognition & Reward Scheme
Annual Company Conference
Regular Happy Hours & Team Lunches
Free Coffee, Drinks & Snacks
