Experience designing and maintaining object-oriented systems in a production codebase.
Experience working with JSON, parsing/serialization, and schema-driven data models.
Ability to debug complex workflows across UI, parsing, API integration, and backend generation logic.
Experience integrating software with REST or HTTP-based APIs.
Ability to work effectively in evolving codebases with mixed legacy and newer patterns.
Strong communication skills and ability to collaborate across software, systems engineering, and platform teams.
Ability to obtain and maintain required DoD Secret security clearance.
