  • 3+ years of relevant experience;
  • Proficiency with the Python programming language and SQL;
  • Strong understanding of data science concepts and techniques, including predictive modeling, machine learning, and statistical analysis;
  • A business-oriented mindset with the ability to translate technical findings into actionable insights;
  • A commitment to code quality and collaborative development, including code reviews, unit testing, and CI/CD practices.

  • Are experienced with cloud platforms such as GCP, AWS or Azure;
  • Are experienced with ML model deployment and management in production settings.


    • Here’s the deal:

  • Growth and learning opportunities: time dedicated to learning, conferences, online learning platforms, and books for your professional development;
  • Health and wellness: we want you to feel and be your best. That's why we offer various benefits, from online workouts, a physical coach and a gym to regular mental health checks;
