About the role

At Tele2, data, AI and agentic tools are already a core part of how we work. As Marketing Data Science Lead, you will extend their impact across Comviq, Tele2 B2C and Tele2 B2B. You will combine marketing science with AI to deepen our customer understanding, measure what drives growth and guide where we invest.

You will be the marketing department’s go-to expert for advanced analytics and AI. You will build models, run experiments and turn customer insights and data into solutions that show what really drives sales and make our marketing smarter. This is a hands‑on role where you will support the whole marketing team in our decisions. You will work closely with the Marketing Director, our AI/Data function and colleagues across marketing.

You will strengthen marketing’s in‑house analytical expertise, building on Tele2’s shared data and AI capabilities.

Key responsibilities

• Build and own our measurement framework, including marketing mix modeling, experimentation and incrementality testing, and systematically test our media spend to understand how we should invest.

• Drive personalization and AI-driven decisioning across channels, together with the marketing team and other commercial teams across the organization.
• Turn complex analyses into clear recommendations that guide budget allocation and business decisions.
• Make data a natural part of the team’s everyday work by improving data quality, building dashboards that give everyone access to insights, setting up smarter ways of working and sharing your knowledge.

• Act as the bridge between marketing and our AI/Data function, making sure new data and AI capabilities turn into real business value.

To be successful in this role, we believe you have...

You combine technical depth with a commercial mindset. You understand what makes customers buy, and you see models and code as tools to find the next business opportunity, not as an end in themselves. You are a doer who likes to get things done. You are eager to explore new AI capabilities and confident in questioning their outputs. You enjoy explaining complex analyses in a simple and engaging way, and you make others curious about what data and AI can do.

We also believe you have:

• Several years of experience in data science or advanced analytics, ideally in e-commerce or another commercial environment close to sales.
• Strong interest in and knowledge of modern MarTech, AI and advanced analytical techniques, including areas such as marketing mix modeling, experimentation, personalization, causal inference and AI-driven decisioning.
• Experience working with market research and customer insights, such as brand tracking, ad tracking or NPS.
• Hands‑on experience with SQL and Python, R or similar, and with cloud data platforms such as Snowflake.
• Experience using AI tools in your everyday analytical work, for example to write code, analyze data or automate tasks.
• Experience working with large amounts of data and presenting insights and recommendations to senior stakeholders, turning them into clear actions and priorities.
• Fluency in both Swedish and English, written and spoken.

You are curious, structured and commercially minded, and you enjoy challenging assumptions with facts.
