Requisitos
What you will do as an Data Scientist in Data Science at OLX:
- Work in the Data Science team, focusing on LLMs and GenAI, from a platform and marketplace perspective.

- Work with Product Analytics to track the KPIs of different ML use cases and measure the impact on our customers.
- Partner with the Experimentation team to integrate the KPIs and their proxies into the Experimentation (A/B testing) platform.
