Commercial Data Scientist Intern - stage chez BookBetter

Ta nouvelle mission

KPI definition: Work directly with the founders to define the most relevant commercial and impact KPIs to steer BookBetter into its next growth phase: from conversion and unit economics to sustainability metrics.
Dashboards & data capabilities: Build clear, actionable dashboards that bring these KPIs to life, linking sources such as PostHog conversion metrics, Power BI, and CRM, on top of our SQL / Databricks data stack, to support prioritisation, decision-making, and strategy building.
Margin & pricing analysis: Make detailed margin calculations based on real operational contracts and setups (payment fees, booking fees, financial transfer fees, look-to-book ratio fees, and more) to sharpen pricing and profitability decisions.
Strategic thinking: Take a real seat at the table: join the founders and the wider team in strategic discussions where your analysis directly shapes the roadmap.
Customer-facing data products: Help create BookBetter's data capabilities by building live dashboards for our airport and destination customers, providing insights on bookings (e.g. setting up a live data model shared with partners such as Rotterdam The Hague Airport), and turning a large pool of travel data into valuable sustainability insights.
A/B testing & experimentation: possibly support the definition and analysis of A/B tests, helping the team measure what actually drives conversion and more sustainable travel choices, and translate results into clear recommendations.

Qui cherchons-nous ?

Last years of studies in Commercial Engineering (Handelsingenieur), TEW / Applied Economics, Business Analytics, Data Science, or a strongly related field.
Internship of minimum 3-4 months as part of your university curriculum.
Comfortable turning data into decisions: strong Excel and data-visualisation skills (e.g. Power BI); hands-on experience or a strong eagerness to learn SQL and modern data platforms such as Databricks, alongside Python and product/marketing analytics tools (e.g. PostHog) and CRM systems, is a real plus.
Commercial and analytical mindset: you enjoy unit economics, margins, and pricing as much as clean dashboards.
Passion for sustainable travel and for building things in a fast-moving startup.
Proactive, entrepreneurial, and able to work independently (partly from home) and in a team.
Fluency in English.

Notre offre

Hands-on experience in a dynamic startup environment, with direct exposure to founders with strategy-consulting and sustainable-aviation backgrounds.
A real voice in strategic decisions: your analysis will genuinely influence where BookBetter goes next.
Opportunity to contribute to a meaningful cause at the intersection of travel, data, and climate.
Mentorship and a strong network in business, aviation, and sustainability, plus strong potential for future full-time employment or references for career advancement.
Significant discounts on international train travel (conditions apply): practice what we preach and explore Europe by rail for up to 5 trips per year
We cover the cost of your commute when travelling to the office in Brussels or going for a day of work with our co-founder in Amsterdam, and we pay your lunch when working in the office. (non-remunerated internship)
