Data Scientist in St Albans

MrQ is looking for a highly skilled Data Scientist to join our growing Revenue Operations team. RevOps is the Architect of the company’s revenue engine and we use maths, statistics data and ML to ensure revenue is protected, predictable and maximised. This role has direct exposure to commercial programmes across every part of the business and we are looking for the highest calibre of talent.

This role has two core areas of focus that sit at the heart of how RevOps drives decisions:

• Causal Inference & Metric Explainability: Design and deploy causal inference frameworks to explain metric movements across acquisition, retention, and revenue — moving the business beyond correlation to confident causal attribution. Build automated decomposition models that identify why a KPI has shifted (e.g. mix effects, seasonality, campaign impact, product changes) and surface actionable root causes to stakeholders. Partner with teams to embed causal thinking into decision-making workflows — replacing gut feel with evidence-backed direction.
• Agentic AI & Always-On Insight: Using the frameworks created for causal inference architect and build specialised AI agents that autonomously monitor key business metrics, detect anomalies, and generate natural language explanations of what is happening and why. Develop agent systems that combine metric surveillance, contextual awareness, and LLM-powered explainability — so insight is proactive, not reactive. Ensure agents are robust, well-validated, and capable of handling the complexity of the business. Continuously improve agent intelligence over time — incorporating new data signals, feedback loops, and evolving business context.

What We’re Looking For:

• Master’s degree (or PhD) in Data Science, Statistics, Mathematics, or related field.
• 5+ years of experience in applied data science, ideally in digital, gaming, gambling, or another high-growth consumer-facing industry.
• Expertise in causal inference methods — including uplift modelling, difference-in-differences, instrumental variables, and causal ML frameworks (e.g. DoWhy, EconML).
• Hands-on experience designing and building AI agents or agentic pipelines, including tool use, orchestration, and LLM integration.
• Expert knowledge of R or Python for statistical modelling and machine learning.
• Excellent SQL skills for querying and transforming large datasets.
• Strong communication skills and proven experience influencing senior stakeholders.

What Success Looks Like:

• In 3 Months: Develop a deep understanding of our data ecosystem and key business drivers. Deliver a first causal analysis or metric decomposition that directly informs a commercial decision. Prototype an initial agentic monitoring system for at least one core business metric.
• In 12 Months: Causal inference frameworks embedded into RevOps' standard toolkit, actively shaping acquisition, retention, and revenue decisions. A suite of specialised AI agents running autonomously — monitoring key metrics and delivering proactive, plain-language insight to stakeholders without manual intervention. Introduced and championed new methodologies (e.g. causal ML, uplift modelling, agentic workflows). Partnered with stakeholders to embed ML products into key business workflows and decisions. Helped shape the RevOps function's research cadence and ways of working.
