What a data engineer does
- Builds pipelines that bring data from your product, tools and partners into one place.
- Designs the warehouse or lakehouse and the tables people query every day.
- Schedules and monitors jobs, and fixes them when a source changes.
- Adds tests and checks, so bad data is caught before anyone uses it.
- Prepares clean data for analytics and machine learning.
Skills to look for
- Strong SQL and Python.
- A cloud warehouse such as Snowflake, BigQuery, Redshift or Databricks.
- Orchestration with Airflow, Dagster or Prefect.
- Transformation with dbt or a similar tool.
- Streaming with Kafka or a managed alternative, if your data needs to arrive in real time.
- Data modeling: when to use a star schema, when to keep raw tables, and how to document both.
Interview questions that show real experience
- Walk me through a pipeline you built. What broke most often, and what did you change?
- A source system renames a column overnight. What happens in your pipeline, and who finds out?
- How do you decide between batch and streaming for a new data source?
- How do you keep warehouse cost under control as the data grows?
Data engineer, analytics engineer or data scientist?
A data engineer builds and runs the pipelines and the storage. An analytics engineer turns that data into clean, tested models for reporting, often with dbt. A data scientist uses the data to answer questions and build models. Many teams hire a data engineer first, because the other two roles depend on good data. If you also plan to run machine learning in production, see hiring MLOps engineers.
Why Latin America for data engineering
Data problems show up during your working day, when someone opens a dashboard and the numbers look wrong. Engineers in Mexico, Peru, Chile, Argentina and Brazil work within a few hours of US time, so the person who can fix it is online at the same time.

Questions companies ask
Does a data engineer need to know machine learning?
No. It helps if you plan ML work, and the core of the job is pipelines, storage and data quality.
Can the engineer work as a contractor?
Yes. We recruit for contractor and full-time roles.
Do I pay anything if I do not hire?
No. You pay only when you hire someone we introduced.
