Senior Data Analyst Advertising

Make your colleagues more performant through analytics

How do you delight our customers?

Bol.com continuously advances its platform to create a better tomorrow for over 13 million customers and over 50,000 trading partners. Our advertising propositions, which help shoppers discover products and advertisers reach customers, play an important role in bol’s ambitions – and here is where you’ll make the difference. Because data informs decisions, frames conversations, and changes perceptions, you rise to the occasion to ensure it is used effectively and responsibly.

The biggest challenge

Advertising via Bol is growing at a fast clip, becoming increasingly important for bol.com. The number of colleagues, the complexity of the tech, and the breadth of initiatives are rapidly expanding. Data needs are no exception. To continue to scale at high velocity, we need meaningful metrics and dimensions to help us talk about our business, insightful analyses, and reliable predictive models. As a data analyst, your contributions here will be invaluable!

What you’ll do as a data analyst

You’ll join an international group of 15+ analytics professionals in Bol’s Advertising Analytics team, supporting a wide range of Product, Commercial, Operation, Strategy, and Finance teams to drive bol.com’s Retail Media business. Together, you share a mission of making people performant through analytics. This role is for the versatile analyst, one that is equally comfortable talking to data as to stakeholders. Your days vary, but at the core you’ll use SQL, Python, and Tableau to provide metrics, analysis, and predictions that help the business make better decisions.

You will develop deep domain knowledge and apply it to create language around our data that is easily interpretable for our internal customers. You then use that language to deliver insights and predictions through dashboards and/or presentations that are so crisp and engaging they would even make good bathroom reading.

You’re a critical thinker and continuously learn to improve on analysis techniques and KPI development. Trying novel methods and techniques? Right up your alley! Venturing into previously unexplored data sets and topics? Just your thing! 0 to 1 projects? Your specialism!

• You work closely with a subset of our business stakeholders (Leadership, Product teams, Sales teams, Operation teams) and collect their requirements for our deliverables.
• With support, you prioritize, design, and perform analysis as well as deliver dashboards in Tableau for self-service analysis.
• Build up extensive domain knowledge so you can effectively develop, monitor, and safeguard the advertising’s business KPIs.
• You write high quality and easily interpretable SQL and Python code that can be reused by colleagues and scales easily as data volumes increase.

Why you can make a difference

You’re a passionate analytics professional who thrives in a collaborative environment. You bring a sharp analytical mindset, a drive to create business impact, and strong communication skills. Proficient in SQL and tools like Tableau, you confidently work with large, complex datasets and translate insights into actionable recommendations.

You lead analytics initiatives, define KPI frameworks, and help shape commercial strategies through data. You design scalable data models and pipelines, contribute to architectural decisions in our GCP-based stack, and apply advanced statistical or machine learning techniques to optimize advertising performance.

As a strategic partner to leadership, you turn business challenges into data-driven solutions. You also mentor junior analysts, fostering a culture of learning and excellence in analytics.

3 reasons why this is (not) for you

• You’re an analytics professional: Yes, if you have 5+ years’ experience delighting business users with your SQL skills. You are bilingual and also write fluently in Python.
• Obsess over building the right things: Yes, if for you it’s not just about delivering output. You strongly feel output does not equal outcome and judge success by value creation.
• You get (and create) energy by working with others: Yes, if you’re well versed in translating technical stuff into language that anyone from the CEO to interns can comprehend. You get energy from both working with data and people.
• If you strongly value clarity: No, if innovating on behalf of the team, autonomy, and ambiguity sound terrifying to you.
• You only want to process data: No, if you only want to process data and think we should get someone else to handle the project and stakeholder management.
• If you believe analysts don’t need domain knowledge: No, if you don’t want to dive into the world of advertising. Willingness to be curious and learn about our domain and our customers is a key ingredient of our recipe to making analysts successful.

This is where you’ll work

You’ll join an international group of 15+ analytics professionals in bol’s Advertising Analytics team which supports a wide range of Product, Commercial, Operation, Strategy and Finance teams to drive bol.com’s Retail Media business.
