Senior Data Scientist

Salary: £70,000 - 110,000 per year

Requirements:

• Masters or PhD in Statistics, Economics, Data Science, Mathematics, Computer Science, or a related field, or equivalent practical experience.
• Strong hands-on experience in measurement, marketing science, experimentation, data science, or analytics, with a track record of delivering business-relevant insights from complex data.
• Strong understanding of causal inference, experimentation, statistical modelling, and media measurement, with practical experience applying approaches such as MMMs, PSA methods, GeoLift, holdout tests, or similar frameworks.
• Able to independently structure ambiguous analytical problems, manage dependencies, and deliver high-quality outputs with consistency and attention to detail.
• Strong ability to connect analytical results to business decisions, investment trade-offs, and financial reality.
• Strong command of Python or R, SQL, and analytical workflows needed to support rigorous, reproducible measurement and modelling.
• Excellent ability to explain complex methods and uncertain results in clear, pragmatic language tailored to different audiences.
• Sound judgement in ambiguous situations, including knowing when to apply advanced methods, when to simplify, when to challenge assumptions, and when to escalate risks or uncertainty.
• Experience working directly with media buying teams or growth marketing organisations.
• Experience contributing to the development of repeatable measurement approaches used in planning or optimisation.
• Familiarity with digital advertising measurement challenges such as attribution bias, selection effects, incrementality gaps, and platform limitations.
• Experience with BigQuery, Looker, Airflow, or similar data ecosystems.
• Passion for gaming and a track record of using data to improve commercial decision-making.

Responsibilities:

• We will own complex measurement workstreams end-to-end, from scoping through analysis and readout, applying sound statistical and experimental methods to assess channel impact, incrementality, and the business contribution of media investment.
• We will design and run incrementality tests and translate model and experiment outputs into clear, commercial insight the business can act on.
• We will apply robust statistical, modelling, and experimentation approaches, including MMMs, PSA techniques, GeoLift, holdout testing, and other causal inference frameworks, to evaluate Performance Marketing effectiveness.
• We will work closely with buying teams, analysts, and technical partners to turn measurement questions into practical test designs, interpret results with appropriate caveats, and help convert learnings into repeatable approaches that support planning, forecasting, and optimisation.
• We will collaborate closely with game design and studio teams, alongside marketing, to connect measurement outcomes directly to player behavior, in-game metrics, and revenue generation.
• We will develop scalable, reusable analytical frameworks and turn experimental outcomes into calibration inputs and practical decision-making tools.
• We will build repeatable processes that integrate measurement directly into media planning, campaign optimisation, and ongoing performance evaluation.
• We will work with marketing and technical stakeholders to translate business questions into measurement plans, analytical requirements, and test designs that are both statistically credible and operationally realistic.
• We will bring informed opinions on how measurement approaches should evolve, identify gaps or risks in current methods, and propose practical improvements.
• We will explain assumptions, trade-offs, confidence levels, and limitations to both technical and non-technical audiences.
