About the Role
As a Data Scientist, you will join the AI Models team at VTEX CX Platform, a business unit of VTEX. You will be responsible for researching, developing, and improving machine learning models that power our conversational agents and multi-agent systems. You are driven by curiosity and impact, transforming complex data into tangible improvements in user experience and product performance.
What you will do
- Research, design, and implement machine learning models to improve the performance of conversational agents and multi-agent systems.
- Analyze large datasets to extract insights that guide model improvements and product decisions.
- Work closely with engineers and product managers to bring AI models from prototype to production.
- Continuously evaluate model performance and iterate based on real-world usage and feedback.
- Perform exploratory data analysis (EDA) to uncover hidden structures, anomalies, and relationships in data, informing hypothesis generation and experimental design for conversational AI systems.
Who you are
- Strong foundation in Statistics.
- Proficiency in Python.
- Experience using Git for code version control.
- Hands-on experience with scikit-learn, pandas, and other data-related frameworks.
- Knowledge of Deep Learning.
- Experience with cloud platforms (AWS) for storage, pipelines, and deployment.
- Monitoring performance, drift, and data quality in production.
- Critical thinking, curiosity, and proactive problem-solving.
- Clear communication (oral, written, and visual) and collaborative teamwork.
- Familiarity with GenAI/LLMs (prompt engineering, fine-tuning, hallucination evaluation).
- Bachelor’s degree in Computer Science, Engineering, Statistics, Mathematics, or related fields.
