Many assume that leadership in software engineering starts only when you stop coding and become a manager. I once shared this belief, thinking technology would be simpler than working with people. That was an early misconception. While it is possible to focus your career on code, architecture, databases, and other technical areas, the challenges that shape your impact become less technical over time. Even the best architectural decision has little value if others do not trust, understand, or support it.This does not mean every experienced software engineer should become a manager. Leadership is equally important on the technical track. Senior individual contributors, such as staff engineers, architects, and principal engineers, are expected to influence decisions beyond their own code. As Will Larson discusses in Staff Engineer, advancing beyond senior engineering focuses on technical leadership rather than people management. To increase your technical impact, others must listen to your ideas, trust your judgment, include you in key discussions, and act on your recommendations. You may choose not to manage people, but avoiding leadership will eventually limit your growth as a software engineer.
