  • Statistical knowledge, especially in complex scenarios like estimations with censored data, non-random sampling or rare event sampling. We like to understand what’s happening under the framework.
  • Good Python: if you believe design and style is much more than aesthetics, this is your place
  • 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 recommendation systems with various sources, especially historical (Collaborative Filtering) and descriptions ( NLP + Content-Based)

  • Knowledge of MLOps lifecycles using Kubeflow, MLFlow…
  • Experience developing web services.

How does our team work?

  • 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.
  • Ownership: we don’t try to close users stories and forget the contest. We have a wide vision about where the pieces fit inside Aplazame’s machinery.

What we offer:

  • 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.

If you believe you’re the right person for this position, we’d love to hear from you. If your proposal sounds interesting, we’ll contact you to have an initial interview so we can get to know each other and will follow these steps:
