Strong scripting or Python skills; ability to run tests, analyze outputs, and automate iterations.
Background in journalism, research, or real-time systems is a major plus.
Ability to think creatively and analytically about language, logic, and information accuracy.
Passion for fast news, clear communication, and building something with meaningful impact.
