  • Must be a highly proficient Python coder capable of using libraries like pandas and boto3 to build scripts and connect to complex APIs.
  • Ability to write, debug, and optimize advanced SQL queries with ease.

• Cloud Expertise: Solid, hands-on experience operating within the AWS ecosystem (Redshift, S3, Glue, Lambda, Step Functions).

• Big Data Tools: Strong background in Apache Spark/PySpark for large-scale data transformations.

• Modern Data Stack: Practical experience with dbt (data build tool) for data transformation and testing.
