Data – Full time – Madrid


BNZSA is a leading European marketing agency specialising in tele-based B2B demand generation for many of the world’s leading IT companies.

We are preparing the foundations to take BNZSA to the next level and are now looking for a Data Scientist to join our Data Team. Do you want to take this challenge with us?

This exciting opportunity for a Data Scientist will have you helping to shape data, owning and presenting your own work demonstrating transformational insight to our business and our client’s businesses – and pushing the boundaries of data being at the core of our initiatives.

Our aim is to use the wealth of data that we have and that our clients have, to create predictions, insights and recommendations. This starts with an exciting project to predict opportunity in our base, and will include bespoke work for our clients based on their 1P data.

Ideal candidate

What You’ll Do

Build analytical products

You will be responsible, in collaboration with the Head of Insights and the Data Engineers, for building a range of products that will enable us to understand customers, prospects and the changing market; to predict next best actions and identify opportunities; to plan and optimize the customer journey, among others. This role will require a combination of creativity, analytical thinking, and pragmatism to make best use of the data we have access to.

Support our teams

Our callers and agents rely on quality data to optimize the conversations they have with clients, customers and prospects. You will help them by enhancing the data they already have, producing derived insights, and give them the information they need to encourage engagement and conversion.

Support our clients

Our clients hold a wealth of historic 1P data. You will be involved in unlocking the potential of their data, identifying cross-sell and up-sell opportunities among existing customers, and supporting them with insights about customer behavior, journeys and next best experiences.

Key Responsibilities

This role requires a good understanding of all phases of the analytic process including data collection, preparation, modelling, evaluation, and insight generation.

You will be working with data engineers, who will support you in shaping and manipulating the data for you to use. You must therefore be collaborative and clear in your instructions, and capable of producing briefs that will support these engineers in their work. You will also be expected to present your work to non-technical audiences, stressing the business benefits and recommendations.

You will demonstrate a high level of expertise in the use of machine learning and statistical techniques. Skills in deep learning, data mining, knowledge extraction and graph theory are also highly desirable.
