Mid-Level Data Scientist

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Mid-Level Data Scientist based in Brazil.

As a Mid-Level Data Scientist, you will help transform digital and behavioral data into actionable insights that support product, marketing, and customer experience decisions. You will work across data integration, analytical modeling, experimentation, and machine learning in a collaborative environment. The role focuses on building reliable data pipelines, analytical layers, and well-governed datasets rather than large-scale streaming or traditional big-data workloads. You will explore user journeys, identify behavioral patterns and friction points, and develop models that enable personalization and better decision-making. Working closely with Product, Engineering, and Analytics teams, you will help strengthen data quality, measurement frameworks, and experimentation practices. This is an opportunity to contribute directly to data-driven initiatives while working with modern cloud, data platform, and development technologies.

• Strong knowledge of digital behavioral analytics, including front-end events, tracking, user journeys, and interaction data.

• Advanced proficiency in SQL, including query optimization, relational modeling, and analytical data modeling.

• Practical experience with Snowflake, including data warehousing, roles, tasks, performance optimization, and cost management.

• Hands-on experience with dbt, including models, tests, sources, and exposures.

• Experience building and maintaining data pipelines with Airflow, including DAGs, sensors, retries, and SLAs, as well as AWS Lambda.

• Knowledge of PostgreSQL, including ingestion, basic replication or CDC, maintenance, and database routines.

• Strong Python experience for data applications, particularly with Pandas, plus experience developing APIs with FastAPI.

• Practical knowledge of batch-oriented ELT/ETL, Git-based version control, and CI/CD practices for safely deploying data pipelines and dbt models.

• Understanding of data security and governance principles, including access control, data lineage, documentation, and sensitive data management.

• Familiarity with cloud and data platform technologies such as AWS, Snowflake, and Airflow.

• Experience with CI/CD tools such as GitHub Actions, GitLab CI, or AWS CodeBuild is a plus.

• Knowledge of Infrastructure as Code using CloudFormation or Terraform is an advantage.

• Familiarity with observability tools such as CloudWatch, Grafana, or Prometheus is a plus.

• Strong analytical thinking, attention to detail, problem-solving skills, and the ability to communicate technical insights clearly.

• Ability to collaborate effectively with multidisciplinary teams and translate complex data findings into understandable business recommendations.
