About The Position
C. Mack Solutions is seeking a UI/UX Developer with strong full-stack development experience to join our team and support a complex program providing Agile development, operations, and maintenance for critical systems on a mission-critical Federal Government program.

This is a hands-on development role: strong coding ability, particularly with React, is the top priority, with UI/UX collaboration as a meaningful secondary responsibility. Experience with Agile development methodologies and the ability to work collaboratively with cross-functional teams, including developers, product owners, and stakeholders, is essential.
