About Konfio

We are the financial technology company in Mexico that has helped more than 70k customers to make their plans come true.

Our purpose is to support small and medium enterprises in the country to fulfill their dreams, through our solutions (financing, credit card and payments) to help solve their main problems.

About the Data Science Team

We are a high-performance team committed to follow best practices, both in modeling and programming, to ensure we deliver the highest quality results.

Our mission at Konfio is to work intelligently, utilizing data, statistics, and models to innovate while simultaneously generating value. As part of the team, you will be able to leverage your knowledge to contribute to this mission, and at the same time, you will be learning, since we are independent professionals but share knowledge and collaborate with each other.

Currently we have robust processes, but that doesn't mean we can't improve them, so proactivity and experimentation are really encouraged.

About the Role

We are looking for a proactive, detail-oriented Data Scientist that can help us to enhance our risk models. The ideal candidate must possess a solid foundation in statistics, mathematics, and programming.

We are particularly interested in individuals who consistently seek improvements and generate innovative ideas. We expect them to be very independent, capable of proposing solutions and requiring little guidance from her or his leader. And we will also give particular emphasis in our selection process for those candidates who not only possess technical expertise but also stand out in effective communication and can transmit complex technical concepts with clarity.

Additionally, the ideal candidate should be an excellent team player and actively contribute to promote an inclusive and diverse work environment.
