Senior Data Analyst Advertising

Senior Data Analyst Advertising  Be the reason a decision actually gets made  How do you help bol make better decisions?
continuously advances its platform to create a better tomorrow for over 13 million customers and 50,000+ trading partners. Our advertising business plays an increasingly important role in that ambition — and increasingly, so does the clarity with which we can explain how it's performing. As a Senior Data Analyst, you're the person leadership and key stakeholders turn to when they need to understand not just what the numbers say, but what to do about it.
Advertising via bol keeps growing, and so does the complexity of explaining why. Revenue moves, but the story behind the movement often doesn't move with it. Is display underperforming, or is the market shifting? Is a driver structural, or a one-off? As a senior analyst you own that story end-to-end: framing the right question, building the analysis that answers it, and staying in the room until the answer actually changes how the business acts.

AI is fast taking over the repetitive parts of this work like dashboarding or descriptive questions, freeing you to spend more time on the analysis and the room, not less.
What you'll do as a Senior Data Analyst – Business Analytics  You'll join 20+ analysts in bol's Advertising Analytics team, working closely with internal stakeholders — Leadership, Finance, Sales, Marketing, and Business Development. Within the Business Analytics sub-team, we aim to be the steering model of the advertising via bol department. We shape the strategy, explain performance and guide execution of core initiatives.
In practice:
Own analyses end-to-end: from framing an ambiguous business question with a stakeholder to shipping the analysis and staying involved until it changes a decision
Build and maintain driver trees and financial narratives that explain how advertising revenue moves, and why
Dive deep into the performance of our advertising propositions, developing domain expertise stakeholders come to rely on
Apply causal inference, statistical, or econometric methods where correlation isn’t good enough — and recognize when it isn’t needed
Use AI to eliminate the low-value repetitive parts of your work, and reinvest that time into deeper analysis and stakeholder engagement
Coach junior analysts on problem framing, technical craft, and operating as a genuine analytical partner rather than an order-taker
Write clean, reusable SQL and Python that scales and solves genuine problems
You have 4+ years of hands-on analytics experience, SQL and Python are second nature, and you know how to turn a messy question into a shipped answer. Here’s the thing: we’re looking for a rounded profile. Some analysts are tech‑savy; comfortable with causal inference, econometrics and our full tech stack. Others are strongest on the domain and ownership side: real retail media domain knowledge, end‑to‑end ownership, staying until insights actually land, coaching junior analysts, and using AI to buy back capacity for higher‑value work.

You can have a spike on one of them, but we want a minimum level for both.
Story finder
You don't stop at "revenue is down." You keep digging until you can say why, and what to do about it.

Insight activator
Your definition of done isn’t a dashboard or a deck. It's the moment a stakeholder makes a better decision because of something you surfaced.

Driven mentor
You make the analysts around you sharper. Not by telling them what to do, but by teaching them how to think.

Dashboard deliverer
You've built some visually stunning dashboards in your career. Which is how you measure their impact.

Lone analyst
Stakeholder management distracts from the real work. You’d rather just interact with data.
