Build the tools that make Studio a video editor people want to live in, including transitions, color grading and elements libraries on top of an in-house engine, plus presets that spare users from tweaking many controls. The role mixes greenfield features with polish on the existing editor, such as one-step keyboard shortcut rebinding for editors coming from Premiere Pro or Final Cut Pro. You write proposals, get fast feedback, and own features through launch, including the marketing moment.
