Position Description

CGI Federal has an exciting opportunity for an Python Developer within our Intel sector advancing the national security mission through cutting edge technology. You must have a passion for keeping pace with rapidly evolving technology advancements and leveraging your knowledge on a highly collaborative team to deliver state of the art capabilities.

. Database Management: Work with various database systems (e.g., Postgres, NoSQL, and Graph) for data storage and retrieval.

. Collaboration: Collaborate with cross functional teams, including frontend developers, product managers to understand requirements, integrate components, and ensure seamless functionality.
