- Work with data originating from data lakes, ETL processes, validation logic, and model outputs at the application layer.
- Work with PostgreSQL, including database migrations and performance-sensitive queries.
- Package and manage applications using Docker.
- Work within existing GraphQL environments and support migrations toward REST-based architectures when appropriate.
- Use AI-assisted development tools to accelerate implementation while critically evaluating generated solutions for maintainability and scalability.
- Collaborate directly with engineering stakeholders to clarify functional and non-functional requirements.
- Work effectively within terminal-centric Mac/Linux development environments.
- Contribute technical perspectives and challenge short-term solutions when a more scalable or maintainable approach is required.

- Exposure to Trino/Presto, BigQuery, Spark SQL, or similar data technologies.
- Familiarity with DAG-based orchestration tools such as Airflow, Dagster, Prefect, or AWS Step Functions.
- Data engineering exposure, including ETL pipelines, advanced SQL, data validation, or query optimization.
- Experience with Redis or DynamoDB.
