Data Engineer

Why should you consider working WITH us?

Bnext鈥檚 mission is to completely disrupt the way people see and interact with money. Creating a financial Brand that users can 鈥渓ove鈥, and allowing them to choose in financial terms like they do in all other aspects of their life, creating one sole financial identity that they can use to spend anywhere in the world and contract any financial product they might need. And that鈥檚 impossible without radically changing how financial platforms work from the inside, how data is structured and manipulated.

We have acquired more clients in the last 12 months than any other Fintech in Spain, and we have the great challenge of ensuring that we fully understand our customer needs to be their main card and to be the first option when hiring financial products. We currently have Engagement Marketing, Growth Marketing, Product and Monetization teams that use the large amount of data we have to achieve their goals. So far the work has focused on creating a solid data architecture and an efficient BI system that allows the analysis of a large amount of data and ensures the quality of the generated data. The next step is to carry out predictive analytics and develop products and services through tools such as Machine Learning and AI that allow to have better vision and control over the objectives as well as to offer better services to the bnexters.
