* Ownership - being able to handle increasingly large tasks on your own with little to no involvement from your manager or lead. * Search IQ - Nobody knows how to do everything in software development off the top of their head, but a major difference between a junior dev and a senior one is knowing what questions to ask and how to find the answers. I didn't used to have a name for this until one of my former mentees told me it's called "search IQ" in China. * Understanding the big picture - At a junior level, you are generally able to understand your small task in the context of what behavior it should be producing. Senior devs should be able to grok development tasks in the context of the business use cases and within the wider system.
