Senior Software Engineers operate as technical leaders within their teams — owning architecture for major features, mentoring junior engineers, leading design reviews, and being trusted to resolve ambiguous, cross-team problems independently. The role is the typical IC ceiling at companies without an explicit staff+ track, and the bridge for those that do.
