Job description

Who are we?

Aquablu makes smart hydration systems. Our REFILL+ dispensers provide filtered, mineralised and flavoured water to offices, gyms and hotels, cutting single-use plastic. Every system is connected, so we know how our customers use it. The next step is using that data to serve them better.

Our team in Amsterdam is looking for a Customer Success Intern to join the team.

The Internship:Starts in Feburary 2027, duration is 6 months, on-site in Amsterdam, 32-40 hours weekly.

About the role:

Our Customer Success & Experience team works with data from HubSpot, our AURA platform, and the systems we have running in the field. In this internship, you'll get hands-on with all of it. You'll join customer conversations, see how the team makes decisions, and find out what data looks like when real customers depend on it.

Your supervisor is there to guide you, but the thinking is yours. Your ideas get heard in team discussions, and from your first week, you're part of the team.

What you'll work on:

• Data structure & hygiene: help make HubSpot our single, reliable source for accounts, renewals and expansion, so separate spreadsheets can go.

• Customer health & churn signals: build health scoring and a dashboard that flags at-risk accounts months in advance.

• Upsell signals: research which usage patterns predict expansion or upsell. This is a strong basis for your thesis.

• Support metrics: redesign how we measure resolution time and ticket quality, and find the root causes of long-running or low-scoring tickets.

• Automation: set up proactive alerts based on machine data (for example, a system that goes offline or stops being used) so we reach customers before they reach us.

About you:

• A final-year HBO or WO student in Business Analytics, Information Management, Business IT, Econometrics, Information Science, or similar, looking for a graduation internship

• Comfortable with data: SQL, Excel/Sheets, and ideally Python or a BI tool. CRM experience (HubSpot) is a plus but not required.

• You like messy data and turning it into something people actually use

• You can explain what you find to non-technical colleagues and take ownership without waiting to be told

• Fluent English;

• Dutch, German, French, or Spanish is a strong plus
