Senior​/Lead Data Analyst - Independent Media Agency

Salary: up to £70,000 + benefits | London | Hybrid

Working with a high-performing independent media agency, this is a pivotal Lead Analyst position sitting at the centre of data, effectiveness and commercial decision-making.

• Solid Python skills - comfortable writing code for data manipulation, modelling, and automation.
• Pragmatic problem-solver who defaults to the simplest solution that works, not the most technically impressive one
• Able to translate analytical findings into a clear narrative, comfortable presenting to clients and non-technical stakeholders.

• Independent agency with a genuine point of difference combining media, data and behavioural science
• Strong investment in analytics, effectiveness and modelling capability
• Exposure to UK and international clients across multiple sectors

• Play a key role in new business pitches and strategic growth projects

• Strong background in marketing analytics, data science or media effectiveness
• Proven experience in modelling, forecasting and statistical analysis
• Solid Python skills - comfortable writing code for data manipulation, modelling, and automation
• Solid understanding of regression techniques and data interpretation
  
  Experience building measurement frameworks or solving effectiveness challenges
• Confident presenting complex outputs to non-technical stakeholders
• Exposure to MMM, geo-testing or incrementality work is a strong plus

This is not a dashboard role. If you’re serious about influencing strategy, owning modelling work that drives investment decisions, and stepping into a more senior, commercially impactful position, this is it.
