Quick Summary

We are looking for a Customer Insights Analyst Intern to join our team in Berlin, Germany. The ideal candidate will have a strong analytical background and experience with data analysis tools. The successful candidate will be responsible for analyzing customer data to inform business decisions and drive growth.

Job Description

Flink is the leading quick commerce player in Europe. We are on a mission to give people back time: You can order your groceries through our app and we deliver to your doorstep in minutes. We carry 3,000 products with a focus on the leading brands in each category. We aim for sustainability by making deliveries on electric bikes and utilizing recyclable packaging. 

Flink launched in February 2021 and already operates in more than 90 cities in Germany, and the Netherlands. The business generated more than EUR 400m in revenues in 2022 and is operationally profitable. Flink is backed by the world’s most renowned tech investors, including Prosus, Mubadala, and Bond, and strategic investors like Doordash and REWE. We take great pride in being an inclusive employer that offers equal opportunities, and we celebrate the diversity and multiculturalism of our team. We're growing fast and always pushing ourselves to do better - we play for #1.

 To stay on top, we need to understand our customers better than anyone else. That's where you come in.

In this internship, you will be at the heart of our strategy to maximize Customer Lifetime Value. 

You'll dive deep into our data to uncover what keeps our customers loyal and identify the key levers to drive long-term retention. Your work will directly influence key business decisions and help shape the future of Flink's customer retention strategy.

Your key responsibilities will include:

• Crack the Code on Retention: You will use causal inference to identify the root causes of churn and the true "drivers of value". You will dig deep into the data to distinguish between correlation and causation, finding out exactly why customers stay or leave and what we can do to extend their lifecycle.
• Bridge the Business Silos: You will work across different domains (Operations, Revenue, Pricing) to understand how different levers impact the customer experience. You will connect the dots between operational performance and customer loyalty.
• Steer Investment with ROI: You will help answer the "Where should we invest?" question. By quantifying the economic impact of retention drivers, you will guide the business toward the initiatives with the highest financial return, directly influencing capital allocation.
• Translate Data to Strategy: You will turn complex analysis into a clear strategic narrative. You will define what needs to change to improve the customer experience and present actionable recommendations to senior leadership.

To succeed in this internship you:

• Have a Quantitative Foundation: You are currently pursuing or have recently completed a Bachelor's, Master's, or Ph.D. in a field such as Data Science, Econometrics, or Statistics.
• Are technically confident: You know the basics in SQL and you have gained first experiences building statistical models in Python or R.
• Proactive Problem Solver: You don't wait for instructions. You have a curious mindset, a passion for understanding customer behavior, and the ability to see the bigger picture while maintaining a keen eye for detail.
•  Speak "Business": You have excellent communication skills with the confidence to present complex information clearly and concisely to senior leaders.

• 26 days of vacation, +1 day every year up to a maximum of 30 days
• A discount on your Urban Sports Club membership
• Attractive company pension options
• Unlimited access to an e-learning and development platform, MyAcademy, including online German courses
• Online discounts with Corporate Benefits and Future Bens
• A cool discount off your personal Flink orders; be the first to test out new products!
• A modern and dog-friendly office in the heart of Berlin - lots of delicious lunch spots available within short walking distance

It is our commitment that every applicant will be evaluated according to their skills regardless of age, gender identity, ethnicity, sexual orientation, disability status, or religion.
