Croud is a highly successful, continually fast-growing agency with ambitious plans for the future. We have a unique agency operating model, which makes things different and exciting; and a brilliant, positive culture. It’s a fantastic place to work.

We are investing in Data Solutions (Within that Data Science & Tools) as a strategic priority. The team brings together a number of capabilities that sat within different parts of Croud, into one unit that will drive cutting edge development in a number of critical areas for the business.

We would like to bring in a Data Scientist with marketing experience to report into the "Head of Data Science & Tools”.

We’re building a team to keep Croud in its market-leading position. Data Science & Tools will invent solutions and deliver them in ways that no-one has thought of, yet. The team is one part of a wider Data Solutions division. It works closely with Digital Analytics, as well as Data Visualisation, Adtech and Ad Ops. The successful candidate in this role as Data Scientist will report to the Head of Data Science & Tools.

The right hire will share Croud’s values:

  • Passion: loving what you do and being driven to excel with each new project
  • Imagination: meeting challenges creatively and ready to try new ideas
  • Integrity: accountable and always excellent to one another


This role is focused on developing and delivering services the team provides for Croud’s clients, including:

  • Predicting the lifetime value of newly acquired customers and making this metric available in near real-time (so that it can drive advertising platform bidding algorithms)
  • Determining the propensity for a website user or new sales lead to purchase
  • Identifying clusters within a customer dataset in order to reveal marketing insight and define audiences for advertising targeting
  • Revealing how performance can be attributed to the visual and auditory characteristics of display and video advertising creative

The Data Science & Tools team also provides services in studying advertising Effectiveness, in integrating and managing data, and in developing tools and automation. We expect that the whole team will work in a fluid, collaborative and supportive manner. Nobody’s work is tied stringently to a spec. Every skill in the team might be applied to solve each problem in Effectiveness, Prediction and Tools Development.

  • Experience visualising and presenting data and the results of modelling, and this may include in interactive dashboards
  • Experience with cloud computing platforms and using them to train and test predictive models, and host them as web services
