Senior Data Scientist II

We are looking for a Staff Data Scientist, Marketing (Senior Data Scientist II) to join Wolt’s mission! 

About the role 

As a Staff Data Scientist supporting Wolt’s Marketing team, you will help shape how we use data to understand, improve, and scale our marketing investments. You’ll work on high-impact questions around growth, efficiency, customer acquisition, and marketing performance across Wolt’s markets.

In this role, you’ll combine deep analytical expertise with hands-on collaboration, working closely with business teams to identify important opportunities, design robust measurement approaches, and guide decisions through data. From uncovering performance drivers to building scalable reporting, experimentation, and monitoring frameworks, you’ll help ensure we are focusing on the right opportunities and investing behind the ideas that truly work.

What you'll be doing

• Own marketing measurement: Help improve how Wolt measures paid marketing performance across channels, campaigns, markets, and customer segments.
• Turn data into decisions: Analyze marketing performance to identify what is driving growth, where spend is efficient, and where teams should adjust investment or execution.
• Improve attribution quality: Develop practical ways to evaluate attribution, understand its limitations, and make performance reporting more accurate, trusted, and useful.
• Build scalable foundations: Create dashboards, analyses, experimentation approaches, and monitoring frameworks that help marketing teams make better decisions faster.

You’ll move fluidly between hands-on analysis and business partnership, ensuring we don’t just report on marketing performance, but use data to improve how we invest, learn, and scale.

Our humble expectations

• 6+ years of experience in an analytics, data science, marketing analytics, growth analytics, or other quantitative role.
• Proficiency in SQL, Python/R, and AI IDE tools, with the ability to work confidently with complex and imperfect business data.
• Hands-on experience analyzing marketing, growth, marketplace, consumer, or performance data to guide practical business decisions.
• Experience with experimentation, attribution, and measurement concepts, with the ability to apply them pragmatically in real-world business settings.
• Strong communication and business partnering skills, with the ability to structure ambiguous questions and drive work from analysis through recommendation.

What we offer

• The online delivery platform that Wolt is building will offer you interesting and complex challenges together with the opportunities to create a big impact with your skills. Lots of geolocational and temporal data in real-time combined with differences in the economics and dynamics of the cities we operate in make Wolt both a challenging and so interesting company to practice analytics. 
• You can work onsite at our offices in Helsinki or Stockholm. Alternatively, you can work remotely anywhere in Finland or Sweden. You have the chance to decide the ways of working — a hybrid, at the office, or remote, within the location above. 💙 
• You would get to work in a company culture where we take ownership beyond the obvious, do common things uncommonly well, we think big but stay humble, do right by people, we treat others kindly and justly, recognize that if we don’t learn, we won’t stay still but fall behind and keep in mind that Luke was Yoda’s greatest achievement.

Next steps

The position will be filled as soon as we find the right person, so make sure to apply as soon as you realize you really, really want to join us!
