Adapting a JD from a 10+ year Technical Lead role to a 4+ year Senior Developer role requires shifting the focus from "strategic architecture and team management" to "technical execution and feature ownership."

At 4+ years, the candidate is expected to be a high-level individual contributor who can work independently and begin mentoring juniors, but they aren't necessarily expected to juggle the entire project's roadmap.
