  • Teamwork and ability to communicate: we’re not rockstars, we work with a lot of people, we understand them and we make ourselves understood.
  • Intellectual curiosity oriented to solving complex problems and not completely defined.

We’ll also considerate (though it’s not a mandatory requirement): 

  • Experience with risk scoring and fraud, knowledge about the financial industry.
  • Experience with bayesian modelling, sequential decision making and reinforcement learning. ,
  • A/B testing for online products.

  • Knowledge of MLOps lifecycles using Kubeflow, MLFlow…

  • Technical Excellence: we try to do everything fine. We tend to improve and try to reach excellence.
  • Intellectual curiosity and individual growth. We make science, we are restless, we ask ourselves questions. Learning is what motivates us.
  • Zero ego: Ego is the enemy. We separate author from results. We don’t fall in love with any idea and everything can be improved.
  • Teamwork: issues and success are shared. We collaborate and genuine interest for our colleagues.
  • Responsible autonomy: we are very flexible about how we work (asyncronous remote work allowing work-life balance and autonomy in the execution). We trust each other.

  • Competitive fixed salary plus 20% annual bonus based on individual and collective objectives.

  • The laptop and accesories of your choice to feel comfortable at work.
  • You’ll work with a team full of stars to learn from and have fun as you grow professionally. We’re humble but ambitious. We’ll love to help you develop. You’ll decide where your limits are.
  • An environment full of confidence and open communication. We are very horizontal. Everyone is welcome to contribute with ideas or experiences in any area.
  • Culture of feedback and learning. We try not to make mistakes, but they are an excellent learning source.
  • Flexible schedule. We pay attention to your results, not the time you come and go.
  • This position is Madrid-based but our culture is remote friendly. You’ll have the chance to work from home when you need to.
