Why Promoting Top Engineers Into Management Often Backfires

A software engineering manager argues that the common career path of moving senior engineers into people management roles is fundamentally flawed. Unlike code, which behaves predictably given the same inputs, managing people involves inherent non-determinism that structured, process-driven thinking cannot resolve. Many tech companies fail to recognize a clear split between technical leadership tracks and people management tracks, instead assuming excellence in one transfers automatically to the other. Engineers wired for structure and predictability often struggle when they attempt to apply those same instincts to managing teams, sometimes resorting to excessive process or counterproductive behavior. The author contends that organizations must treat people leadership as a distinct skill set requiring deliberate evaluation and development, not a default promotion for high-performing engineers.
