Job Description:
Senior Experimentation Data Scientist (Contract) Sector: eCommerce
Contract Length: 3 months

Day Rate: £650-£700 per day
Location: Hybrid - 2 days per week onsite
Overview We are supporting a leading eCommerce business in the search for a Senior Experimentation Data Scientist to deliver high-impact experimentation across logistics and operational initiatives. This role is explicitly not product-focused and will centre on experimentation relating to promotions, operational efficiency, and logistics performance.
This is a fast-moving engagement with tight timelines, requiring someone who can hit the ground running and operate autonomously within a squad-based delivery model.
Key Responsibilities * Design and execute experimentation frameworks focused on logistics and operational use cases
* Lead A/B testing and controlled experiments to evaluate promotional and operational changes
* Ensure analytical robustness through sense-checking data, assumptions, and outputs
* Work closely with engineers, analysts, and operational stakeholders within a squad environment
* Translate experimental outcomes into clear, actionable recommendations for the business
* Operate independently while maintaining strong collaboration across technical teams
Technical Requirements Essential
* Advanced SQL (including joins, validation logic, and data interrogation)
* Strong Python for analysis and experimentation workflows
* Experience working with Google BigQuery or comparable cloud data platforms
Experimentation Expertise
* Proven experience designing and building experimentation frameworks
* Strong grounding in experimental design, statistical validity, and bias mitigation
* Confident explaining experimental approaches verbally, not just via documentation
Ideal Contractor Profile * Senior-level experimentation data scientist with strong commercial awareness
* Comfortable working at pace in short, delivery-focused contracts
* Able to work independently with minimal oversight
* Confident partnering with highly technical teams
* Well-prepared, pragmatic, and delivery-oriented
* Comfortable operating within tight timelines and changing priorities
