About the team/company:

  • Feedzai develops fraud prevention solutions based on Machine Learning. One of our key differentiators is the ability to put in place such solutions at very large scales and at blazing fast speeds
  • As clients we have some of the largest payment processors in the world, which gives us access to really, really large datasets
  • This problem is complex because of the sheer amount of data involved, the very short time to make a decision, and the fact that as soon as you create a better solution, fraudsters start learning to work around it

As a Data Scientist, your main role is to do Data Science work on projects for our clients. Occasionally this can be done from our offices, but often this will be done at clients' premises for security reasons, so there is a significant travel component involved (in some cases more than 30%).

Responsibilities:

  • Understanding the data which our clients provide to us
  • Cleaning that data and validating that it is correct
  • Preprocessing the data, usually by using a mixture of shell scripts and a programming language such as Python, Java, Scala, etc
  • Iteratively computing features and tuning parameters to improve the quality of the model
  • Communicating your findings to the project manager and assisting him/her in decision making on the Data Science part of the project
  • Work together with the data scientists and engineers from our clients

Requirements:

  • Knowledge of Machine Learning basics such as training and testing, avoiding overfit, etc
  • Knowledge of Random Forests is a plus
  • Knowledge of Big Data technologies such as Spark, Hadoop and related
  • Proficiency in bash, Python and either Java or Scala
  • Knowledge of resource monitoring and runtime optimization (both at JVM and OS level) - knowledge of statistics or data visualization is a plus
  • Ability to communicate your findings in a clear way

Benefits:

  • Take part in one of the fastest-growing startups in the market;
  • High impact with a small but growing team;
  • Health insurance;
  • Free fruit;
  • International Free Coffee Selection;
  • Weekly workplace gymnastics.
